Critical Thinking and Decision-Making: What is Critical Thinking?

Lesson 1: what is critical thinking, what is critical thinking.

Critical thinking is a term that gets thrown around a lot. You've probably heard it used often throughout the years whether it was in school, at work, or in everyday conversation. But when you stop to think about it, what exactly is critical thinking and how do you do it ?

Watch the video below to learn more about critical thinking.

Simply put, critical thinking is the act of deliberately analyzing information so that you can make better judgements and decisions . It involves using things like logic, reasoning, and creativity, to draw conclusions and generally understand things better.

This may sound like a pretty broad definition, and that's because critical thinking is a broad skill that can be applied to so many different situations. You can use it to prepare for a job interview, manage your time better, make decisions about purchasing things, and so much more.

The process

As humans, we are constantly thinking . It's something we can't turn off. But not all of it is critical thinking. No one thinks critically 100% of the time... that would be pretty exhausting! Instead, it's an intentional process , something that we consciously use when we're presented with difficult problems or important decisions.

Improving your critical thinking

In order to become a better critical thinker, it's important to ask questions when you're presented with a problem or decision, before jumping to any conclusions. You can start with simple ones like What do I currently know? and How do I know this? These can help to give you a better idea of what you're working with and, in some cases, simplify more complex issues.  

Real-world applications

Let's take a look at how we can use critical thinking to evaluate online information . Say a friend of yours posts a news article on social media and you're drawn to its headline. If you were to use your everyday automatic thinking, you might accept it as fact and move on. But if you were thinking critically, you would first analyze the available information and ask some questions :

• What's the source of this article?
• Is the headline potentially misleading?
• What are my friend's general beliefs?
• Do their beliefs inform why they might have shared this?

After analyzing all of this information, you can draw a conclusion about whether or not you think the article is trustworthy.

Critical thinking has a wide range of real-world applications . It can help you to make better decisions, become more hireable, and generally better understand the world around you.

Critical Thinking

Developing the right mindset and skills.

By the Mind Tools Content Team

We make hundreds of decisions every day and, whether we realize it or not, we're all critical thinkers.

We use critical thinking each time we weigh up our options, prioritize our responsibilities, or think about the likely effects of our actions. It's a crucial skill that helps us to cut out misinformation and make wise decisions. The trouble is, we're not always very good at it!

In this article, we'll explore the key skills that you need to develop your critical thinking skills, and how to adopt a critical thinking mindset, so that you can make well-informed decisions.

What Is Critical Thinking?

Critical thinking is the discipline of rigorously and skillfully using information, experience, observation, and reasoning to guide your decisions, actions, and beliefs. You'll need to actively question every step of your thinking process to do it well.

Collecting, analyzing and evaluating information is an important skill in life, and a highly valued asset in the workplace. People who score highly in critical thinking assessments are also rated by their managers as having good problem-solving skills, creativity, strong decision-making skills, and good overall performance. [1]

Key Critical Thinking Skills

Critical thinkers possess a set of key characteristics which help them to question information and their own thinking. Focus on the following areas to develop your critical thinking skills:

Being willing and able to explore alternative approaches and experimental ideas is crucial. Can you think through "what if" scenarios, create plausible options, and test out your theories? If not, you'll tend to write off ideas and options too soon, so you may miss the best answer to your situation.

To nurture your curiosity, stay up to date with facts and trends. You'll overlook important information if you allow yourself to become "blinkered," so always be open to new information.

But don't stop there! Look for opposing views or evidence to challenge your information, and seek clarification when things are unclear. This will help you to reassess your beliefs and make a well-informed decision later. Read our article, Opening Closed Minds , for more ways to stay receptive.

Logical Thinking

You must be skilled at reasoning and extending logic to come up with plausible options or outcomes.

It's also important to emphasize logic over emotion. Emotion can be motivating but it can also lead you to take hasty and unwise action, so control your emotions and be cautious in your judgments. Know when a conclusion is "fact" and when it is not. "Could-be-true" conclusions are based on assumptions and must be tested further. Read our article, Logical Fallacies , for help with this.

Use creative problem solving to balance cold logic. By thinking outside of the box you can identify new possible outcomes by using pieces of information that you already have.

Self-Awareness

Many of the decisions we make in life are subtly informed by our values and beliefs. These influences are called cognitive biases and it can be difficult to identify them in ourselves because they're often subconscious.

Practicing self-awareness will allow you to reflect on the beliefs you have and the choices you make. You'll then be better equipped to challenge your own thinking and make improved, unbiased decisions.

One particularly useful tool for critical thinking is the Ladder of Inference . It allows you to test and validate your thinking process, rather than jumping to poorly supported conclusions.

Developing a Critical Thinking Mindset

Combine the above skills with the right mindset so that you can make better decisions and adopt more effective courses of action. You can develop your critical thinking mindset by following this process:

Gather Information

First, collect data, opinions and facts on the issue that you need to solve. Draw on what you already know, and turn to new sources of information to help inform your understanding. Consider what gaps there are in your knowledge and seek to fill them. And look for information that challenges your assumptions and beliefs.

Be sure to verify the authority and authenticity of your sources. Not everything you read is true! Use this checklist to ensure that your information is valid:

• Are your information sources trustworthy ? (For example, well-respected authors, trusted colleagues or peers, recognized industry publications, websites, blogs, etc.)
• Is the information you have gathered up to date ?
• Has the information received any direct criticism ?
• Does the information have any errors or inaccuracies ?
• Is there any evidence to support or corroborate the information you have gathered?
• Is the information you have gathered subjective or biased in any way? (For example, is it based on opinion, rather than fact? Is any of the information you have gathered designed to promote a particular service or organization?)

If any information appears to be irrelevant or invalid, don't include it in your decision making. But don't omit information just because you disagree with it, or your final decision will be flawed and bias.

Now observe the information you have gathered, and interpret it. What are the key findings and main takeaways? What does the evidence point to? Start to build one or two possible arguments based on what you have found.

You'll need to look for the details within the mass of information, so use your powers of observation to identify any patterns or similarities. You can then analyze and extend these trends to make sensible predictions about the future.

To help you to sift through the multiple ideas and theories, it can be useful to group and order items according to their characteristics. From here, you can compare and contrast the different items. And once you've determined how similar or different things are from one another, Paired Comparison Analysis can help you to analyze them.

The final step involves challenging the information and rationalizing its arguments.

Apply the laws of reason (induction, deduction, analogy) to judge an argument and determine its merits. To do this, it's essential that you can determine the significance and validity of an argument to put it in the correct perspective. Take a look at our article, Rational Thinking , for more information about how to do this.

Once you have considered all of the arguments and options rationally, you can finally make an informed decision.

Afterward, take time to reflect on what you have learned and what you found challenging. Step back from the detail of your decision or problem, and look at the bigger picture. Record what you've learned from your observations and experience.

Critical thinking involves rigorously and skilfully using information, experience, observation, and reasoning to guide your decisions, actions and beliefs. It's a useful skill in the workplace and in life.

You'll need to be curious and creative to explore alternative possibilities, but rational to apply logic, and self-aware to identify when your beliefs could affect your decisions or actions.

You can demonstrate a high level of critical thinking by validating your information, analyzing its meaning, and finally evaluating the argument.

What is Critical Thinking?

Critical Thinking Definition

September 2, 2005, by The Critical Thinking Co. Staff

The Critical Thinking Co.™ "Critical thinking is the identification and evaluation of evidence to guide decision making. A critical thinker uses broad in-depth analysis of evidence to make decisions and communicate their beliefs clearly and accurately."

Other Definitions of Critical Thinking: Robert H. Ennis , Author of The Cornell Critical Thinking Tests "Critical thinking is reasonable, reflective thinking that is focused on deciding what to believe and do."

A SUPER-STREAMLINED CONCEPTION OF CRITICAL THINKING Robert H. Ennis, 6/20/02

Assuming that critical thinking is reasonable reflective thinking focused on deciding what to believe or do, a critical thinker:

1. Is open-minded and mindful of alternatives 2. Tries to be well-informed 3. Judges well the credibility of sources 4. Identifies conclusions, reasons, and assumptions 5. Judges well the quality of an argument, including the acceptability of its reasons, assumptions, and evidence 6. Can well develop and defend a reasonable position 7. Asks appropriate clarifying questions 8. Formulates plausible hypotheses; plans experiments well 9. Defines terms in a way appropriate for the context 10. Draws conclusions when warranted, but with caution 11. Integrates all items in this list when deciding what to believe or do

Critical Thinkers are disposed to:

1. Care that their beliefs be true, and that their decisions be justified; that is, care to "get it right" to the extent possible. This includes the dispositions to

a. Seek alternative hypotheses, explanations, conclusions, plans, sources, etc., and be open to them b. Endorse a position to the extent that, but only to the extent that, it is justified by the information that is available c. Be well informed d. Consider seriously other points of view than their own

2. Care to present a position honestly and clearly, theirs as well as others'. This includes the dispositions to

a. Be clear about the intended meaning of what is said, written, or otherwise communicated, seeking as much precision as the situation requires b. Determine, and maintain focus on, the conclusion or question c. Seek and offer reasons d. Take into account the total situation e. Be reflectively aware of their own basic beliefs

3. Care about the dignity and worth of every person (a correlative disposition). This includes the dispositions to

a. Discover and listen to others' view and reasons b. Avoid intimidating or confusing others with their critical thinking prowess, taking into account others' feelings and level of understanding c. Be concerned about others' welfare

Critical Thinking Abilities:

Ideal critical thinkers have the ability to (The first three items involve elementary clarification.)

1. Focus on a question

a. Identify or formulate a question b. Identify or formulate criteria for judging possible answers c. Keep the situation in mind

2. Analyze arguments

a. Identify conclusions b. Identify stated reasons c. Identify unstated reasons d. Identify and handle irrelevance e. See the structure of an argument f. Summarize

3. Ask and answer questions of clarification and/or challenge, such as,

a. Why? b. What is your main point? c. What do you mean by…? d. What would be an example? e. What would not be an example (though close to being one)? f. How does that apply to this case (describe a case, which might well appear to be a counter example)? g. What difference does it make? h. What are the facts? i. Is this what you are saying: ____________? j. Would you say some more about that?

(The next two involve the basis for the decision.)

4. Judge the credibility of a source. Major criteria (but not necessary conditions):

a. Expertise b. Lack of conflict of interest c. Agreement among sources d. Reputation e. Use of established procedures f. Known risk to reputation g. Ability to give reasons h. Careful habits

5. Observe, and judge observation reports. Major criteria (but not necessary conditions, except for the first):

a. Minimal inferring involved b. Short time interval between observation and report c. Report by the observer, rather than someone else (that is, the report is not hearsay) d. Provision of records. e. Corroboration f. Possibility of corroboration g. Good access h. Competent employment of technology, if technology is useful i. Satisfaction by observer (and reporter, if a different person) of the credibility criteria in Ability # 4 above.

(The next three involve inference.)

6. Deduce, and judge deduction

a. Class logic b. Conditional logic c. Interpretation of logical terminology in statements, including (1) Negation and double negation (2) Necessary and sufficient condition language (3) Such words as "only", "if and only if", "or", "some", "unless", "not both".

7. Induce, and judge induction

a. To generalizations. Broad considerations: (1) Typicality of data, including sampling where appropriate (2) Breadth of coverage (3) Acceptability of evidence b. To explanatory conclusions (including hypotheses) (1) Major types of explanatory conclusions and hypotheses: (a) Causal claims (b) Claims about the beliefs and attitudes of people (c) Interpretation of authors’ intended meanings (d) Historical claims that certain things happened (including criminal accusations) (e) Reported definitions (f) Claims that some proposition is an unstated reason that the person actually used (2) Characteristic investigative activities (a) Designing experiments, including planning to control variables (b) Seeking evidence and counter-evidence (c) Seeking other possible explanations (3) Criteria, the first five being essential, the sixth being desirable (a) The proposed conclusion would explain the evidence (b) The proposed conclusion is consistent with all known facts (c) Competitive alternative explanations are inconsistent with facts (d) The evidence on which the hypothesis depends is acceptable. (e) A legitimate effort should have been made to uncover counter-evidence (f) The proposed conclusion seems plausible

8. Make and judge value judgments: Important factors:

a. Background facts b. Consequences of accepting or rejecting the judgment c. Prima facie application of acceptable principles d. Alternatives e. Balancing, weighing, deciding

(The next two abilities involve advanced clarification.)

9. Define terms and judge definitions. Three dimensions are form, strategy, and content.

a. Form. Some useful forms are: (1) Synonym (2) Classification (3) Range (4) Equivalent expression (5) Operational (6) Example and non-example b. Definitional strategy (1) Acts (a) Report a meaning (b) Stipulate a meaning (c) Express a position on an issue (including "programmatic" and "persuasive" definitions) (2) Identifying and handling equivocation c. Content of the definition

10. Attribute unstated assumptions (an ability that belongs under both clarification and, in a way, inference)

(The next two abilities involve supposition and integration.)

11. Consider and reason from premises, reasons, assumptions, positions, and other propositions with which they disagree or about which they are in doubt -- without letting the disagreement or doubt interfere with their thinking ("suppositional thinking")

12. Integrate the other abilities and dispositions in making and defending a decision

(The first twelve abilities are constitutive abilities. The next three are auxiliary critical thinking abilities: Having them, though very helpful in various ways, is not constitutive of being a critical thinker.)

13. Proceed in an orderly manner appropriate to the situation. For example:

a. Follow problem solving steps b. Monitor one's own thinking (that is, engage in metacognition) c. Employ a reasonable critical thinking checklist

14. Be sensitive to the feelings, level of knowledge, and degree of sophistication of others

15. Employ appropriate rhetorical strategies in discussion and presentation (orally and in writing), including employing and reacting to "fallacy" labels in an appropriate manner.

Examples of fallacy labels are "circularity," "bandwagon," "post hoc," "equivocation," "non sequitur," and "straw person."

Dewey, John Critical thinking is "active, persistent, and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends (Dewey 1933: 118)."

Glaser (1) an attitude of being disposed to consider in a thoughtful way the problems and subjects that come within the range of one's experiences, (2) knowledge of the methods of logical inquiry and reasoning, and (3) some skill in applying those methods. Critical thinking calls for a persistent effort to examine any belief or supposed form of knowledge in the light of the evidence that supports it and the further conclusions to which it tends. (Glaser 1941, pp. 5-6).

Abilities include: "(a) to recognize problems, (b) to find workable means for meeting those problems, (c) to gather and marshal pertinent information, (d) to recognize unstated assumptions and values, (e) to comprehend and use language with accuracy, clarity and discrimination, (f) to interpret data, (g) to appraise evidence and evaluate statements, (h) to recognize the existence of logical relationships between propositions, (i) to draw warranted conclusions and generalizations, (j) to put to test the generalizations and conclusions at which one arrives, (k) to reconstruct one's patterns of beliefs on the basis of wider experience; and (l) to render accurate judgments about specific things and qualities in everyday life." (p.6)

MCC General Education Initiatives "Critical thinking includes the ability to respond to material by distinguishing between facts and opinions or personal feelings, judgments and inferences, inductive and deductive arguments, and the objective and subjective. It also includes the ability to generate questions, construct, and recognize the structure of arguments, and adequately support arguments; define, analyze, and devise solutions for problems and issues; sort, organize, classify, correlate, and analyze materials and data; integrate information and see relationships; evaluate information, materials, and data by drawing inferences, arriving at reasonable and informed conclusions, applying understanding and knowledge to new and different problems, developing rational and reasonable interpretations, suspending beliefs and remaining open to new information, methods, cultural systems, values and beliefs and by assimilating information."

Nickerson, Perkins and Smith (1985) "The ability to judge the plausibility of specific assertions, to weigh evidence, to assess the logical soundness of inferences, to construct counter-arguments and alternative hypotheses."

Moore and Parker , Critical Thinking Critical Thinking is "the careful, deliberate determination of whether we should accept, reject, or suspend judgment about a claim, and the degree of confidence with which we accept or reject it."

Delphi Report "We understand critical thinking to be purposeful, self-regulatory judgment which results in interpretation, analysis, evaluation, and inference, as well as explanation of the evidential, conceptual, methodological, criteriological, or contextual considerations upon which that judgment is based. CT is essential as a tool of inquiry. As such, CT is a liberating force in education and a powerful resource in one's personal and civic life. While not synonymous with good thinking, CT is a pervasive and self-rectifying human phenomenon. The ideal critical thinker is habitually inquisitive, well-informed, trustful of reason, open-minded, flexible, fair-minded in evaluation, honest in facing personal biases, prudent in making judgments, willing to reconsider, clear about issues, orderly in complex matters, diligent in seeking relevant information, reasonable in the selection of criteria, focused in inquiry, and persistent in seeking results which are as precise as the subject and the circumstances of inquiry permit. Thus, educating good critical thinkers means working toward this ideal. It combines developing CT skills with nurturing those dispositions which consistently yield useful insights and which are the basis of a rational and democratic society."

A little reformatting helps make this definition more comprehensible:

We understand critical thinking to be purposeful, self-regulatory judgment which results in

• interpretation

as well as explanation of the

• methodological
• criteriological

considerations upon which that judgment is based.

Francis Bacon (1605) "For myself, I found that I was fitted for nothing so well as for the study of Truth; as having a mind nimble and versatile enough to catch the resemblances of things … and at the same time steady enough to fix and distinguish their subtler differences; as being gifted by nature with desire to seek, patience to doubt, fondness to meditate, slowness to assert, readiness to consider, carefulness to dispose and set in order; and as being a man that neither affects what is new nor admires what is old, and that hates every kind of imposture."

A shorter version is "the art of being right."

Or, more prosaically: critical thinking is "the skillful application of a repertoire of validated general techniques for deciding the level of confidence you should have in a proposition in the light of the available evidence."

Critical Thinking

Critical thinking is a term used by educators to describe forms of learning, thought, and analysis that go beyond the memorization and recall of information and facts. In common usage, critical thinking is an umbrella term that may be applied to many different forms of learning acquisition or to a wide variety of thought processes. In its most basic expression, critical thinking occurs when students are analyzing, evaluating, interpreting, or synthesizing information and applying creative thought to form an argument, solve a problem, or reach a conclusion.

Critical thinking entails many kinds of intellectual skills, including the following representative examples:

• Developing well-reasoned, persuasive arguments and evaluating and responding to counterarguments
• Examining concepts or situations from multiple perspectives, including different cultural perspectives
• Questioning evidence and assumptions to reach novel conclusions
• Devising imaginative ways to solve problems, especially unfamiliar or complex problems
• Formulating and articulating thoughtful, penetrating questions
• Identifying themes or patterns and making abstract connections across subjects

Critical thinking is a central concept in educational reforms that call for schools to place a greater emphasis on skills that are used in all subject areas and that students can apply in all educational, career, and civic settings throughout their lives. It’s also a central concept in reforms that question how teachers have traditionally taught and what students should be learning—notably, the 21st century skills movement, which broadly calls on schools to create academic programs and learning experiences that equip students with the most essential and in-demand knowledge, skills, and dispositions they will need to be successful in higher-education programs and modern workplaces. As higher education and job requirements become competitive, complex, and technical, proponents argue, students will need skills such as critical thinking to successfully navigate the modern world, excel in challenging careers, and process increasingly complex information.

Critical thinking also intersects with debates about assessment and how schools should measure learning acquisition. For example, multiple-choice testing formats have been common in standardized testing for decades, yet the heavy use of such testing formats emphasizes—and may reinforce the importance of—factual retention and recall over other skills. If schools largely test and award grades for factual recall, teachers will therefore stress memorization and recall in their teaching, possibly at the expense of skills such as critical thinking that are vitally important for students to possess but far more challenging to measure accurately.

What Is Critical Thinking? | Definition & Examples

Published on 25 September 2022 by Eoghan Ryan .

Critical thinking is the ability to effectively analyse information and form a judgement.

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

• Identify credible sources
• Evaluate and respond to arguments
• Assess alternative viewpoints
• Test hypotheses against relevant criteria

Why is critical thinking important, critical thinking examples, how to think critically, frequently asked questions.

Critical thinking is important for making judgements about sources of information and forming your own arguments. It emphasises a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In an academic context, critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyse the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words ‘sponsored content’ appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarise it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it a blog? A newspaper article?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Critical thinking refers to the ability to analyze information objectively and make a reasoned judgment. It involves the evaluation of sources, such as data, facts, observable phenomena, and research findings.

Good critical thinkers can draw reasonable conclusions from a set of information, and discriminate between useful and less useful details to solve problems or make decisions. Employers prioritize the ability to think critically—find out why, plus see how you can demonstrate that you have this ability throughout the job application process. 

Why Do Employers Value Critical Thinking Skills?

Employers want job candidates who can evaluate a situation using logical thought and offer the best solution.

 Someone with critical thinking skills can be trusted to make decisions independently, and will not need constant handholding.

Hiring a critical thinker means that micromanaging won't be required. Critical thinking abilities are among the most sought-after skills in almost every industry and workplace. You can demonstrate critical thinking by using related keywords in your resume and cover letter, and during your interview.

Examples of Critical Thinking

The circumstances that demand critical thinking vary from industry to industry. Some examples include:

• A triage nurse analyzes the cases at hand and decides the order by which the patients should be treated.
• A plumber evaluates the materials that would best suit a particular job.
• An attorney reviews evidence and devises a strategy to win a case or to decide whether to settle out of court.
• A manager analyzes customer feedback forms and uses this information to develop a customer service training session for employees.

Promote Your Skills in Your Job Search

If critical thinking is a key phrase in the job listings you are applying for, be sure to emphasize your critical thinking skills throughout your job search.

Add Keywords to Your Resume

You can use critical thinking keywords (analytical, problem solving, creativity, etc.) in your resume. When describing your  work history , include top critical thinking skills that accurately describe you. You can also include them in your  resume summary , if you have one.

For example, your summary might read, “Marketing Associate with five years of experience in project management. Skilled in conducting thorough market research and competitor analysis to assess market trends and client needs, and to develop appropriate acquisition tactics.”

Mention Skills in Your Cover Letter

Include these critical thinking skills in your cover letter. In the body of your letter, mention one or two of these skills, and give specific examples of times when you have demonstrated them at work. Think about times when you had to analyze or evaluate materials to solve a problem.

Show the Interviewer Your Skills

You can use these skill words in an interview. Discuss a time when you were faced with a particular problem or challenge at work and explain how you applied critical thinking to solve it.

Some interviewers will give you a hypothetical scenario or problem, and ask you to use critical thinking skills to solve it. In this case, explain your thought process thoroughly to the interviewer. He or she is typically more focused on how you arrive at your solution rather than the solution itself. The interviewer wants to see you analyze and evaluate (key parts of critical thinking) the given scenario or problem.

Of course, each job will require different skills and experiences, so make sure you read the job description carefully and focus on the skills listed by the employer.

Top Critical Thinking Skills

Keep these in-demand critical thinking skills in mind as you update your resume and write your cover letter. As you've seen, you can also emphasize them at other points throughout the application process, such as your interview. 

Part of critical thinking is the ability to carefully examine something, whether it is a problem, a set of data, or a text. People with  analytical skills  can examine information, understand what it means, and properly explain to others the implications of that information.

• Asking Thoughtful Questions
• Data Analysis
• Interpretation
• Questioning Evidence
• Recognizing Patterns

Communication

Often, you will need to share your conclusions with your employers or with a group of colleagues. You need to be able to  communicate with others  to share your ideas effectively. You might also need to engage in critical thinking in a group. In this case, you will need to work with others and communicate effectively to figure out solutions to complex problems.

• Active Listening
• Collaboration
• Explanation
• Interpersonal
• Presentation
• Verbal Communication
• Written Communication

Critical thinking often involves creativity and innovation. You might need to spot patterns in the information you are looking at or come up with a solution that no one else has thought of before. All of this involves a creative eye that can take a different approach from all other approaches.

• Flexibility
• Conceptualization
• Imagination
• Drawing Connections
• Synthesizing

Open-Mindedness

To think critically, you need to be able to put aside any assumptions or judgments and merely analyze the information you receive. You need to be objective, evaluating ideas without bias.

• Objectivity
• Observation

Problem Solving

Problem-solving is another critical thinking skill that involves analyzing a problem, generating and implementing a solution, and assessing the success of the plan. Employers don’t simply want employees who can think about information critically. They also need to be able to come up with practical solutions.

• Attention to Detail
• Clarification
• Decision Making
• Groundedness
• Identifying Patterns

Ideas to Action (i2a)

• Paul-Elder Critical Thinking Framework

Critical thinking is that mode of thinking – about any subject, content, or problem — in which the thinker improves the quality of his or her thinking by skillfully taking charge of the structures inherent in thinking and imposing intellectual standards upon them. (Paul and Elder, 2001). The Paul-Elder framework has three components:

• The elements of thought (reasoning)
• The  intellectual standards that should be applied to the elements of reasoning
• The intellectual traits associated with a cultivated critical thinker that result from the consistent and disciplined application of the intellectual standards to the elements of thought

According to Paul and Elder (1997), there are two essential dimensions of thinking that students need to master in order to learn how to upgrade their thinking. They need to be able to identify the "parts" of their thinking, and they need to be able to assess their use of these parts of thinking.

Elements of Thought (reasoning)

The "parts" or elements of thinking are as follows:

• All reasoning has a purpose
• All reasoning is an attempt to figure something out, to settle some question, to solve some problem
• All reasoning is based on assumptions
• All reasoning is done from some point of view
• All reasoning is based on data, information and evidence
• All reasoning is expressed through, and shaped by, concepts and ideas
• All reasoning contains inferences or interpretations by which we draw conclusions and give meaning to data
• All reasoning leads somewhere or has implications and consequences

Universal Intellectual Standards

The intellectual standards that are to these elements are used to determine the quality of reasoning. Good critical thinking requires having a command of these standards. According to Paul and Elder (1997 ,2006), the ultimate goal is for the standards of reasoning to become infused in all thinking so as to become the guide to better and better reasoning. The intellectual standards include:

Intellectual Traits

Consistent application of the standards of thinking to the elements of thinking result in the development of intellectual traits of:

• Intellectual Humility
• Intellectual Courage
• Intellectual Empathy
• Intellectual Autonomy
• Intellectual Integrity
• Intellectual Perseverance
• Confidence in Reason
• Fair-mindedness

Characteristics of a Well-Cultivated Critical Thinker

Habitual utilization of the intellectual traits produce a well-cultivated critical thinker who is able to:

• Raise vital questions and problems, formulating them clearly and precisely
• Gather and assess relevant information, using abstract ideas to interpret it effectively
• Come to well-reasoned conclusions and solutions, testing them against relevant criteria and standards;
• Think open-mindedly within alternative systems of thought, recognizing and assessing, as need be, their assumptions, implications, and practical consequences; and
• Communicate effectively with others in figuring out solutions to complex problems

Each year it sponsors an annual International Conference on Critical Thinking and Educational Reform. It has worked with the College Board, the National Education Association, the U.S. Department of Education, as well as numerous colleges, universities, and school districts to facilitate the implementation of critical thinking instruction focused on intellectual standards. The following studies demonstrate:

• the fact that, as a rule, critical thinking is not presently being effectively taught at the high school, college and university level, and yet
• it is possible to do so.

To assess students' understanding of critical thinking, we recommend use of the International Critical Thinking Test as well as the Critical Thinking Interview Profile for College Students . To assess faculty understanding of critical thinking and its importance to instruction, we recommend the Critical Thinking Interview Profile For Teachers and Faculty . By registering as a member of the community, you will have access to streaming video, which includes a sample student interview with Dr. Richard Paul and Rush Cosgrove.

Executive Summary

(Complete Study is available for purchase.)  On September 29, 1994 Governor Wilson signed legislation authored by Senator Leroy Greene (SB1849) directing the Commission on Teacher Credentialing to conduct a study of teacher preparation programs to assess the extent to which these programs prepare candidates for teaching credentials to teach critical thinking and problem-solving skills in elementary and secondary schools. During the spring of 1995, Commission staff began to conceptualize a study design that would yield descriptive information on course content and teaching practices being employed by postsecondary faculty to train teacher candidates. With assistance from the Center for Critical Thinking at Sonoma State University, an interview protocol was designed for use in telephone interviews with a cross-section of education and subject matter faculty in both public and private colleges and universities in California. During the study planning process, a decision was made to design respondent selection procedures in such a way as to assure that information collected would be generalizable to all faculty preparing teachers across the state. To accomplish this objective, two statewide probability samples were designed: a sample of teacher education faculty, and a separate sample of Arts and Sciences faculty teaching courses in Commission-approved subject matter programs. There were three major objectives in this study. The first was to assess current teaching practices and knowledge of critical thinking among faculty teaching in teacher preparation programs in California. The second was to identify exemplary teaching practices that enhance critical thinking. The third was to develop policy recommendations based on the results of the study. The study included 38 public colleges and universities and 28 private ones.

The Concept of Critical Thinking and Problem Solving Used in the Study

The concept of critical thinking and problem solving used in this study is "minimalist," that is, one which captures the essential dimensions of the concept reflected in the following: its etymology and dictionary definition, major definitions and explanations in the literature, a brief history of the idea, major tests of critical thinking, and the basic values it presupposes. This minimalist concept of critical thinking is embedded not only in a core body of research over the last 30 to 50 years but is also derived from roots in ancient Greek. The word ’’critical’’ derives etymologically from two Greek roots: "kriticos" (meaning discerning judgment) and "kriterion" (meaning standards). Etymologically, then, the word implies the development of "discerning judgment based on standards." In Webster's New World Dictionary, the relevant entry reads "characterized by careful analysis and judgment" and is followed by the gloss: "critical, in its strictest sense, implies an attempt at objective judgment so as to determine both merits and faults." Applied to thinking, then, we might provisionally define critical thinking as thinking that explicitly aims at well-founded judgment and hence utilizes appropriate evaluative standards in the attempt to determine the true worth, merit, or value of something. The tradition of research into critical thinking reflects the common perception that human thinking left to itself often gravitates toward prejudice, over-generalization, common fallacies, self-deception, rigidity, and narrowness. The critical thinking tradition seeks ways of understanding the mind and then training the intellect so that such "errors", "blunders", and "distortions" of thought are minimized. It assumes that the capacity of humans for good reasoning can be nurtured and developed by an educational process aimed directly at that end. It assumes that sound critical thinking maximizes our ability to solve problems of importance to us by helping us both to avoid common mistakes and to proceed in the most rational and logical fashion. For example, those who think critically typically engage in intellectual practices of the following sort, monitoring, reviewing, and assessing: goals and purposes; the way issues and problems are formulated; the information, data, or evidence presented for acceptance, interpretations of such information, data, or evidence; the quality of reasoning presented or developed, basic concepts or ideas inherent in thinking, assumptions made, implications and consequences that may or may not follow; points of view and frames of reference. In monitoring, reviewing and assessing these intellectual constructs, those who think critically characteristically strive, for such intellectual ends as clarity, precision, accuracy, relevance, depth, breadth, and logicalness. Each of these modes of thinking help us to accomplish the ends for which we are thinking and hence to solve the problems inherent in pursuing those ends.

Current Teaching Practices and Knowledge of Critical Thinking

In-depth interviews were utilized to provide information on how faculty tend to think about critical thinking and the manner in which that thinking influences the design of their classes. Questions were designed to shed light on the extent to which students in teacher preparation programs in California are being taught in ways that facilitate skill in critical thinking and the ability to teach it to others. There were three goals of this component of the study. The first was to ensure that any faculty who had a developed notion of critical thinking (of any kind) would have a full opportunity and much encouragement to spell out that notion. We wanted to make sure that everyone interviewed was encouraged to express their actual views and to express them in detail. The second goal was to examine the views expressed to see: a) how many faculty actually had a developed view and b) how much internal coherence there was in any given faculty view. In other words, we sought to determine how many faculty had seriously thought through the concept of critical thinking--irrespective of how they defined it, and then, once we had a full expression of any given person's views, we examined what was said, not only for clarity but also for coherence. The third goal was to determine the extent to which the views expressed demonstrated an internalization of traditional "minimalist" elements of critical thinking. We sought to determine, in other words, how much of the common core of meaning now attached to the traditional concept by those working in the field of critical thinking research (and reflected in its semantics and history) has been internalized by faculty teaching in teacher preparation programs. Data collection included both closed-ended and open-ended questions. In addition, the coders of responses made judgments about some important global features of the responses made (using minimalist components of critical thinking as criteria). The open-ended questions, and the follow-up questions, were designed, as indicated above, to provide maximum opportunity for individuals to articulate virtually any concept of critical thinking that they favored. The follow-up questions’’ main function was that of ensuring that the most specific and precise views that could be obtained were obtained. Since the interviews lasted 45 minutes on average, the interviewees had ample opportunity to express their views. The same interview protocol was utilized for both education faculty and subject matter faculty. A total of 140 interviews were completed, representing a 78% response rate among those contacted for an interview. Since the samples were constructed so as to be representative in a statistical sense of all faculty involved in teacher preparation in California, the results can in fact be generalized to teacher preparation faculty in the state as a whole. The results of the analysis were as follows: 1) Though the overwhelming majority (89%) claimed critical thinking to be a primary objective of their instruction, only a small minority (19%) could give a clear explanation of what critical thinking is. Furthermore, according to their answers, only 9% of the respondents were clearly teaching for critical thinking on a typical day in class. 2) Though the overwhelming majority (78%) claimed that their students lacked appropriate intellectual standards (to use in assessing their thinking), and 73% considered that students learning to assess their own work was of primary importance, only a very small minority (8%) could enumerate any intellectual criteria or standards they required of students or could give an intelligible explanation of what those criteria and standards were. 3) While 50% of those interviewed said that they explicitly distinguish critical thinking skills from traits, only 8% were able to provide a clear conception of the critical thinking skills they thought were most important for their students to develop. Furthermore the overwhelming majority (75%) provided either minimal or vague allusion (33%) or no allusion at all (42%) to intellectual traits of mind. 4) When asked how they conceptualized truth, a surprising 41% of those who responded to the question said that knowledge, truth and sound judgment are fundamentally a matter of personal preference or subjective taste. 5) Although the majority (67%) said that their concept of critical thinking is largely explicit in their thinking, only 19% could elaborate on their concept of thinking. 6) Although the vast majority (89%) stated that critical thinking was of primary importance to their instruction, 77% of the respondents had little, limited or no conception of how to reconcile content coverage with the fostering of critical thinking. 7) Although the overwhelming majority (81%) felt that their department’s graduates develop a good or high level of critical thinking ability while in their program, only 20% said that their departments had a shared approach to critical thinking, and only 9% were able to clearly articulate how they would assess the extent to which a faculty member was or was not fostering critical thinking. The remaining respondents had a limited conception or no conception at all of how to do this. 8) Although the vast majority (89%) stated that critical thinking was of primary importance to their instruction, only `a very small minority could clearly explain the meanings of basic terms in critical thinking. For example, only 8% could clearly differentiate between an assumption and an inference, and only 4% could differentiate between an inference and an implication. 9) Only a very small minority (9%) mentioned the special and/or growing need for critical thinking today in virtue of the pace of change and the complexities inherent in human life. Not a single respondent elaborated on the issue. 10) In explaining their views of critical thinking, the overwhelming majority (69%) made either no allusion at all, or a minimal allusion, to the need for greater emphasis on peer and student self-assessment in instruction. 11) From either the quantitative data directly, or from minimal inference from those data, it is clear that a significant percentage of faculty interviewed (and, if representative, most faculty):

• do not understand the connection of critical thinking to intellectual standards.
• are not able to clarify major intellectual criteria and standards.
• inadvertently confuse the active involvement of students in classroom activities with critical thinking in those activities. 
• are unable to give an elaborated articulation of their concept of critical thinking. 
• cannot provide plausible examples of how they foster critical thinking in the classroom.
• are not able to name specific critical thinking skills they think are important for students to learn.
• are not able to plausibly explain how to reconcile covering content with fostering critical thinking.
• do not consider reasoning as a significant focus of critical thinking.
• do not think of reasoning within disciplines as a major focus of instruction.
• cannot specify basic structures essential to the analysis of reasoning.
• cannot give an intelligible explanation of basic abilities either in critical thinking or in reasoning .
• do not distinguish the psychological dimension of thought from the intellectual dimension.
• have had no involvement in research into critical thinking and have not attended any conferences on the subject.
• are unable to name a particular theory or theorist that has shaped their concept of critical thinking.

Some Policy Recommendations

If it is essential for teachers to foster critical thinking, then it is essential for those who teach the teachers to have at least baseline knowledge of the concept of critical thinking. Those who teach prospective teachers must be sufficiently well-informed about critical thinking not only to be able to explain it in a general way to their students, they must also regularly model instruction for critical thinking in their own classroom procedures and policies. The design of their classes must reflect an explicit critical thinking orientation, so that students not only systematically think through the content of their courses, but also come to see how the design of a course can require and cultivate critical thinking and thoughtfulness — or fail to do so. On our view, four interventions are requisite for substantive change to occur. First, we must disseminate the information faculty need to change their perceptions. Second, we must provide for faculty skill-building through appropriate professional development. Third, we must establish a mandate to systematically teach critical thinking (and how to teach for it) in all programs of teacher education. And fourth, we must develop an exit examination in critical thinking for all prospective teachers. Let us look at each of these proposed interventions in turn. 1) Information Dissemination: Sufficient awareness, grounded in intellectual humility, must be generated in those communities of faculty teaching in teacher preparation programs leading to the recognition a) that there is a general lack of knowledge on the part of the teaching faculty of the baseline concept of critical thinking, and b) that most students in teacher preparation programs are now graduating without knowledge of critical thinking or how to teach for it. There are seven forms of information that need wide dissemination. At present none of these categories of information are widely disseminated in the teaching community. The categories are as follows:

• We need to disseminate information that documents the problem at the k-12 teaching level. 
• We need to disseminate information on teaching for critical thinking within particular disciplines (such as math). 
• We need to disseminate information about the process that faculty go through as they initially develop their ability to bring critical thinking successfully into the classroom (especially regarding those who display intellectual humility). 
• We need to disseminate information about exemplary teaching practices of individuals, as they reach high levels of success.

Qualitative Generalizations: Interpreting Responses to Open-Ended Questions

A close look at the open-ended responses obtained in the interviews provides a realistic sense of the empirical foundation for generalizations that go beyond purely quantitative data. Many of the samples from the interviews are vivid and deeply revealing. A full airing of these samples, with commentary, is contained in Appendix A. The data collected enabled us to present illustrative profiles of faculty who had a vague and or internally incoherent conception of critical thinking in contrast to those who had a developed notion of critical thinking (irrespective of their orientation toward it). If we assume that those who had a vague or internally contradictory concept of critical thinking simply haven't thought much on the subject, and those who had a clear, well-elaborated, and internally coherent concept had thought seriously about the subject, then we can infer that comparatively few faculty members have thought seriously about critical thinking. In other words, we were able to get a strong sense of how many faculty members had seriously thought through the concept of critical thinking--irrespective of how they defined it, and then, we were able to separate out those whose views were not only highly elaborated but coherent. From delving into the rich details of the open-ended responses, one finds not only confirmation of the quantitative data, but also powerful support for significant qualitative generalizations. What is more, a close look at individual cases reveals that there is significant contrast between those faculty members who have a developed concept of critical thinking and those who do not. The profiles of individual faculty that are summarized below illustrate clearly the kind of differences which existed between those who were articulate in explaining how they approach critical thinking and those who were not. It also confirmed what the quantitative data showed, namely, that many faculty members, without knowing it, are confused about the basic concepts and skills of critical thinking. Let us now look at some illustrative faculty profiles from the study Each profile represents one person from the study. Each profile is anonymous--in keeping with the commitment made to all of those who agreed to be interviewed.

Some Illustrative Profiles

The Basic Pattern What follows is a series of "profiles" which suggest some of the basic patterns of thinking found in particular faculty members who participated in the interviews. Most faculty answered open-ended questions with vague answers, rather than clear and precise answers. In many of their answers there were internal "tensions" and in some cases outright contradictions. The magic talisman were phrases like "constructivism", "Bloom's Taxonomy", "process-based", "inquiry-based", "beyond recall", "active learning", "meaning-centered" and such like — phrases that under probing questions the majority of interviewees were unable to intelligibly explain in terms of critical thinking. The most common confusion, perhaps, was confusion between what is necessary (for critical thinking) and what is sufficient (for it). For example, active engagement is necessary to critical thinking, but one can be actively engaged and NOT THINK CRITICALLY. To illustrate, many gang members are actively engaged in gang activities, but that does not make them critical thinkers. It is not THAT you are engaged but HOW you are engaged that matters. Virtually all of those interviewed identified critical thinking and the learning of intellectual standards as primary objectives in instruction, yet few could give a clear explanation of what their concept of either was. Virtually all said that students lacked intellectual standards when they entered their classes, yet implied, at the same time, that they left with those intellectual standards in place. They also overwhelmingly stated or implied that their students left them with a good level of critical thinking as well as a good level of ability to foster critical thinking in their future students. By direct statement or by implication, most claimed that they permeated their instruction with an emphasis on critical thinking and that the students internalized the concepts in their courses as a result. Yet only the rare interviewee mentioned the importance of students thinking clearly, accurately, precisely, relevantly, or logically, etc.  Very few mentioned any of the basic skills of thought, such as the ability to clarify questions, gather relevant data, reason to logical or valid conclusions, identify key assumptions, trace significant implications, or enter without distortion into alternative points of view. Intellectual traits of mind, such as intellectual humility, intellectual perseverance, intellectual responsibility, and so on, are virtually unheard of by the interviewees. After listening to the interviews it becomes obvious that irrespective of the diversity of language used, the central problem is that most faculty have not carefully thought through any concept of critical thinking, have no sense of intellectual standards they can put into words, and are, therefore, by any reasonable interpretation, in no position to foster critical thinking in their own students or to help them to foster it in their future students--except to inculcate into their students the same vague views that they have. Now let's look at some specific profiles.

Weak Profiles

Profile A (8) Professor A thinks of critical thinking as of primary importance in his instructional objectives. He identifies his concept of critical thinking as intuitive and a product of his own thinking. He does not distinguish critical thinking skills, traits, and values. According to him, his students come to class with well-developed intellectual standards and graduate with a good level of critical thinking ability and a high level of ability to foster critical thinking in their future students. His responses to the open-ended questions, however, are quite vague in general and suggest that he hasn't in fact thought much about critical thinking. His explanation of critical thinking, for example, is vague and possibly self-contradictory: "Critical thinking means to think analytically and be aware that everyone thinks for himself. All thinking is critical to some extent. Anyone who thinks intelligently. Reflectiveness." When asked what critical thinking skills are most important for students to develop, he says, "I can't answer this. I can't identify skills." When asked how he would assess the extent to which another faculty member was or was not fostering critical thinking in their classes, the vagueness of his thinking about critical thinking is again apparent when he says "You look at their publishing. And I'd hear from students. They'd be complaining. It takes time." When asked for his personal conception of intellectual standards, it is clear that he does not have one: "That’s a hard question to answer. I don't think I see an answer to it." In addition to his general lack of clear thinking about critical thinking, it is apparent that he is also confused about the basic concepts in critical thinking. When asked to explain the difference between an assumption and an inference, he says, "An inference is something based on information. An assumption is based on feeling and a lack of thinking." (Ignoring the fact that we can make empirically well-founded assumptions and infer something based on prejudices or stereotypes.)

Profile B (10) Professor B thinks of critical thinking as of primary importance in her instructional objectives. She says her concept of critical thinking is explicit and a product of her own thinking. She does not distinguish critical thinking skills, traits, and values. According to her, students come to class with well-developed intellectual standards and graduate with a good level of critical thinking ability and a high level of ability to foster critical thinking in their future students. Her responses to the open-ended questions, however, are quite vague in general and suggest that she hasn't clarified the difference between "constructing beliefs" and "constructing knowledge." She in general assumes that if students are actively engaged and "thinking for themselves", they are ipso facto thinking critically. Nowhere does she mention that students actively construct prejudice as well as knowledge, poor thinking as well as sound thinking. Nowhere does she mention the importance of students thinking clearly, accurately, precisely, relevantly, logically, etc... When asked to explain her concept of critical thinking, she says: "Critical thinking consists in the active construction of knowledge and valuing social justice, a continuing examining of things as they are and might be..." When asked what critical thinking skills are most important for students to develop, she says, "I don't think in terms of critical thinking skills. To think critically is to be a competent observer of events and to have a disposition to ask questions about them, to classify and find patterns...". (Note that a person can have the disposition to ask superficial or loaded questions and that all persons, poor reasoners as well as good reasoners, classify and find patterns--merely in virtue of being language users). When asked how she would assess the extent to which another faculty member was or was not fostering critical thinking in their classes, she equates critical thinking with active learning, saying: "Critical thinking is built into an active learning model. How are we supporting students in becoming active, autonomous learners. Active participation, reflection, a personal experience and the ability to make connection between their own views and others. Lively dialogue." When asked for her personal conception of intellectual standards, she looks to find a way to equate intellectual standards with active processing, saying: "A process conception. There is no finite set of standards to achieve but the learner engages in active dialogue with self and others with increasingly insightful learning..." Profile C (14) Professor C thinks of critical thinking as of primary importance in his instructional objectives. He identifies his concept of critical thinking as explicit and a product of one or more theories of critical thinking to which he explicitly subscribes. He claims to distinguish critical thinking skills, traits, and values. According to him, his students do not come to class with well-developed intellectual standards, but graduate with a good level of critical thinking ability and good ability to foster critical thinking in their future students. His responses to the open-ended questions, however, are quite vague in general and suggest that he assumes that critical thinking is an automatic by-product of the use of discipline-based procedures. It is evident, however, that he has not thought through what the differences are between, say, the "scientific method" and "Bloom's taxonomy." He nowhere discusses the standards and criteria implicit in sound scientific work. His explanation of critical thinking is: "Critical thinking is investigative inquiry, to observe, interpret, and predict." When asked what critical thinking skills are most important for students to develop, he says, "To analyze, predict, compare, observe... all of those listed by Bloom...all the science processes." When asked how he would assess the extent to which another faculty member was or was not fostering critical thinking in their classes, he says "Ask them to compare a lecture approach with an investigative inquiry approach. Have them do a self-assessment after they did an inquiry unit." Though the above answer suggests that Professor C understands the importance of having students engage in self- and peer-assessment, it is also clear that he has not thought through the intellectual criteria or standards that students need to effectively do such self-assessment. To some extent, he appears to equate intellectual standards with intellectual autonomy (forgetting that I can think for myself and yet do a poor job of it). For example, when asked for his personal conception of intellectual standards, he says: "All thoughts should be tentative. Are we using the processes and holding thoughts tentatively. In all cases, we should let the students develop their own level of understanding." In addition to his vague thinking about critical thinking, it is apparent that he is also confused about the basic concepts in critical thinking. When asked to explain the difference between an assumption and an inference, and says, "Assumptions don't have data behind them. Inferences do." In saying this, he of course fails to remember that assumptions can be well or poorly grounded and inferences are sometimes based on stereotypes or imagined facts. Nowhere in the interview does Professor C mention any of the basic skills of thought such as clarifying the question; gathering relevant data, reasoning to logical or valid conclusions; identifying key assumptions; tracing significant implications, or entering without distortion into alternative points of view, neither does he mention important intellectual traits of mind, such as intellectual humility, intellectual perseverance, intellectual responsibility, etc... Profile D (15) Professor D illustrates a person who seems torn between negating critical thinking and its importance while simultaneously claiming to permeate her teaching with it (as something vitally important). On the one hand, she says that critical thinking is of primary importance in her instructional objectives, but on the other hand, says that "it is not so much critical thinking (that students need) but information." On the one hand she says that critical thinking is explicit in her thinking and that it is a product of one or more theories of critical thinking to which she explicitly subscribes, but she goes on to say that "I never read critical thinking books." She says that critical thinking "is embedded in everything I do," but cannot articulate any critical thinking skills or standards that she emphasizes. Profile E Professor E (16) illustrates a person who seems torn between a view in which critical thinking is based on objective standards and skills, on the one hand, and a subjective view, on the other (in which whatever satisfies the individual as an autonomous thinker is the only ultimate basis for critical thought). This tension is suggested in Professor E's explanation of his concept of critical thinking: "Information must be processed. To analyze and synthesize a viewpoint that is your own is critical thinking. Values come into it. We should have the capacity to look at things objectively." When he delineates skills that are important for students to develop, he names values and process, but does not clearly state any skill as such: "(They need to learn) objectivity, (to) weigh through information, balance views, accept new information and process it" When Professor E explains his conception of intellectual standards we see again him oscillating between the objective and subjective. He says that "...accuracy and truth are both relative. ... What is the truth at that moment? (But) be available to find that one is not accurate and that the truth is not comfortable," At the same time Professor E is one of the rare individuals who ranks program graduates as low both in critical thinking abilities and in knowledge of how to teach for critical thinking. Profile F (19) Professor F thinks of critical thinking as of primary importance in her instructional objectives. She says her concept of critical thinking is explicit and a product of one or more theories to which she explicitly subscribes (though unable to cite any theory when asked). She says she does distinguish critical thinking skills, traits, and values. According to her, students come to class without well-developed intellectual standards but graduate with a good level of critical thinking ability and in fostering critical thinking in their future students. Her responses to the open-ended questions, however, are peppered with a diversity of responses (and it is not quite clear whether they add up to a coherent notion or represent confusion of thought). Nowhere does she mention that students actively construct prejudice as well as knowledge, poor thinking as well as sound thinking. Nowhere does she mention the importance of students thinking clearly, accurately, precisely, relevantly, logically, etc... When asked to explain her concept of critical thinking, she says: "Everyone has a different view of critical thinking. I think of it as thinking skills. I think of words like analytical, evaluative, judgmental and I think of my field and activities I would do with my students. Logic and patterns. For example, classifying skills. Looking at a set of buttons--which one is different. I'm thinking of open-endedness, unifying ideas, and problem-solving." She provides a similar answer when asked for her personal conception of intellectual standards: "Open-endedness, trying something new, analyze situations and problem solve, making estimates to see if your answers are reasonable, consider the viewpoint, judge the data, check their work." She is unable to give a coherent explanation of the difference between an assumption and an inference or between an inference and an implication. Profile G (76) Professor G is a good example of one who equates critical thinking with thinking for oneself and, beyond that, applies no discernible intellectual standards. She says critical thinking is of primary importance in her instructional objectives, that her concept of critical thinking is explicit and a product of her own thinking. She does not distinguish critical thinking skills, traits, and values. On the other hand, she says that knowledge, truth, and sound judgment are not fundamentally a matter of one's personal preference or subjective taste. She says that it is of primary importance for students to acquire sound intellectual criteria or standards and to learn how to assess their own work. According to her, students come to class without well-developed intellectual standards but graduate with a good level of critical thinking ability and a high level of ability to foster critical thinking in their future students. When asked to explain her concept of critical thinking she says: "Critical thinking is being able to look at a situation and analyze what is going on and ask questions that enable you to get at alternatives. To be able to make up your mind by getting beyond the rhetoric." Her responses to the open-ended questions, however, are quite vague and suggest that she hasn't clarified, for example, the difference between "constructing beliefs" and "constructing knowledge." She in general assumes that if students are actively engaged and "thinking for themselves", they are ipso facto thinking critically. Nowhere does she mention that students can actively construct prejudice as well as knowledge, poor thinking as well as sound thinking. Nowhere does she mention the importance of students thinking clearly, accurately, precisely, relevantly, logically, etc... When asked to describe a typical day in class that fosters critical thinking she says: "I use a holistic, constructivist basis. Students construct their own meaning, working together, dynamic, in living and breathing class discussions and debates." When asked what critical thinking skills are most important for students to develop, she is quite vague. She says, "Being able to assess validity, to look at and assess their own work, what the next step ought to be, to be able to choose issues that are important." When asked how she would assess the extent to which another faculty member was or was not fostering critical thinking in their classes, she equates critical thinking with active learning, saying: . "I would look at students' products. Look for originality. Going beyond the task." When asked for her personal conception of intellectual standards, she says: "(I would look for them to) take their own positions. I don't know that I would apply general standards." She is unclear about the differences between assumptions, inferences, and implications. Profile H Professor H (79) is representative of the many faculty members who equate the fact of students actively "processing" information with their thinking critically about it. Most of those who think this way tend to think in terms of Bloom's taxonomy. Hence, critical thinking then is viewed as going beyond "knowledge" acquisition. Knowledge acquisition is viewed essentially as lower order memorization and recall, while "processing" is viewed as going beyond recall to "internalization". Professor H thinks of critical thinking as of primary importance in his instructional objectives. He identifies his concept of critical thinking as explicit and a product of his own thinking (as well as theory). He says he distinguishes critical thinking skills, traits, and values (though his subsequent answers do not support this claim). According to him, his students do not come to class with well-developed intellectual standards, but that it is "of primary importance" that they acquire such standards and learn thereby to assess their own work. He claims that students in the program graduate with a good level of critical thinking ability as well as a good level of ability to foster critical thinking in their future students. His responses to the open-ended questions, however, are vague and suggest that he hasn't in fact thought much about critical thinking. He explains his concept of critical thinking as follows: "Critical thinking is analyzing an event before a decision is made." He says that "almost all" of his instruction is based on critical thinking because "as long as it is not knowledge acquisition, it is critical thinking. Students analyze and draw their own conclusions." When asked what critical thinking skills are most important for students to develop, he says, "The skills of analysis and recognition of multiple perspectives and then picking out the appropriate action." When asked how he would assess the extent to which another faculty member was or was not fostering critical thinking in their classes, he says "Do they go beyond recall to have the students analyzing and putting it back together to make a decision on their own?" When asked for his personal conception of intellectual standards, he says "Are they using all the information? (Are they considering) multiple viewpoints?" His understanding of basic critical thinking terms is vague. He explains the difference between an assumption and an inference as follows: "An assumption is something that takes place automatically. In an inference you are going in some direction." Concerning the difference between an inference and an implication, he says: "An inference is more biased. An implication is sounder judgments, something that would follow a chain of events." (Note, he is unaware that inferences can be valid or invalid, well or poorly supported, and an implication to thought follows whether or not we ever act upon it--and hence need not be related to any chain of events).

Strong Profiles

Profile J (26) Professor J thinks of critical thinking as of primary importance in his instructional objectives. He identifies his concept of critical thinking as a product of one or more theories of critical thinking to which he explicitly subscribes. He does not distinguish critical thinking skills, traits, and values. According to him, his students graduate with a good level of critical thinking ability and a good level of ability to foster critical thinking in their future students. His responses to the open-ended questions, however, are relatively clear and elaborated. He cites Paulo Friere and John Dewey as fundamental influences in his thinking about critical thinking. He says his main goal is the "empowerment" of students. He says he strives to model critical thinking with his students in a variety of ways, including evaluating various aspects of the course with the students (e.g., what structures being used are working and which are not having their designed effect). He is especially concerned with the intellectual and linguistic development of students and in encouraging students to begin to take charge of their minds and their lives. He develops special strategies to use in helping students to read critically and he challenges the students continually to examine their own presuppositions, as well as the presuppositions of the status quo, of society, of schooling--not excepting his own instructional design. Rather than focus on covering information, professor J helps students to learn skills of finding and assessing information. He concentrates his effort on key concepts which help students assimilate new information. He wants students to discover different modes of thinking that enable them to question dominant sources of information. He wants students to develop a critical understanding of the social context of education and often has students discuss the ultimate purpose of education. Gaining perspective, learning new frames of reference, questioning assumptions, evaluating information for its relevance to their values, involving students in more "authentic" modes of assessment--these are central goals and emphases. Professor J has a well-elaborated conception of intellectual standards. He emphasizes students clarifying their views, evaluating relevance, identifying implications, accurately recognizing presuppositions, determining the coherence of views presented, adhering to the rigors of the scientific method with its goals of accuracy and precision, evaluating reasoning for its validity, and striving for soundness in judgment. Profile K (25) Professor K thinks of critical thinking as of primary importance in her instructional objectives. She says her concept of critical thinking is explicit and a product of one of more theories of critical thinking to which she explicitly subscribes. She cites Matthew Lipman as a fundamental source of theory. She does distinguish critical thinking skills, traits, and values. According to her, students do not come to class with well-developed intellectual standards but he thinks they do graduate with a good level of critical thinking ability and a high good of ability to foster critical thinking in their future students. Her responses to the open-ended questions are relatively clear and well-elaborated. She defines critical thinking as effective problem solving. She fosters it by systematically confronting students, contradicting them to get them to think. She models alternative views, plays devil's advocate, and holds students responsible for their thinking. Hence, though she is a "constructivist" she does not assume that students will automatically construct knowledge simply because they are actively engaged. She believes they must experience careful cultivation within an environment in which they are systematically challenged. She believes in "whole-hearted responsibility." Students must own their decisions and be accountable. She designs her classes so that students must evaluate each other's work. She uses a case study approach, but one in which students critique other students on their cases studies. She uses lecture to present theory, but then students are forced to critique their own understanding of the theories and apply them to their cases. She focuses 40% to 50% of class time on interactive activities, but she holds students responsible for a level of performance in those activities. She designs ways to hold students responsible to do their assigned reading so that they are prepared for the in-class work. She argues that students must continually go back and forth between experience and theory, and between thinking and reflecting on where that thinking is coming from. She argues that students must become conscious of their own theories and what they are based on. Theories must be considered with their objections. Professor K's conception of intellectual standards is framed in the context of the above remarks. Students must express and defend their views, hear objections and answer the objections, hear other views and learn from those views. They must consider alternatives and check their reasoning to make sure it is logical. They must also check their information sources. Professor L (18) Professor L is important as a rare example of a professor whose answers regarding critical thinking reflect intellectual humility. She explicitly admits that her knowledge of critical thinking is limited. She tries to make critical thinking primary in her classes, but she freely admits that she has only her only critical thinking intuitions to go on. In her view critical thinking is the ability to define a problem and develop a solution to it. It includes recognizing strategies that are effective, using criteria for "correct" performance, and then assessing their own performance. Concerning reconciling content coverage with fostering critical thinking, she says that if you give students the material so fast that they are not able to learn it, then coverage makes no sense. She gives a good example from volleyball. She says it would do you no good to hear lectures on volleyball if you are not able to use them effectively in performance of the game. Concerning the component skills of critical thinking, she freely admits that she has never studied critical thinking intellectually, and so "I'm not sure how to explain it." Concerning her personal conception of intellectual standards, her refreshing answer is "This is something I haven't thought about." (The strength of this profile is in the intellectual humility that it displays. This is a professor who is clearly ready to learn.) Professor M (92) Professor M thinks of critical thinking as of primary importance to his instructional objectives. He thinks of knowledge, truth and sound judgment as not fundamentally a matter of his own personal preference or subjective taste. He does not distinguish between critical thinking skills and traits. He was one of the few faculty members in the study to state that the students in his department develop only a low level ability to think critically. Professor M's responses to the open ended questions were relatively clear and elaborated. He sees critical thinking as "being able to reach the sensible conclusions on the basic of logic and evidence, the ability to perceive contradictions...to attempt to resolve them." He says that on a typical class day he focuses on "presenting problems to students as opposed to conclusions." In terms of the critical thinking skills he thinks are the most important for students to develop, he says they most need to develop the ability to seek and evaluate evidence, to use logic to reach defensible conclusions. Furthermore he says that they must be able to evaluate positions of their own and others, "to go beyond superficial understandings of reality." Professor M says that he places strong emphasis on helping students develop philosophical underpinnings of their eventual teaching procedures through a critical thinking approach. He goes on to say that he wants to students to "approach teaching as an intellectual task as opposed to a technical one. One of his primary objectives is to help students develop their ability to gather relevant points of view when dealing with broad, complex issues. Furthermore, he expresses the view that teachers should not present students with "finished answers." Rather they should help students construct their own meanings by teaching them to think through issues in a critical manner. In focusing on the philosophy of education, he presents the key concept as "a logically consistent interrelated set of principles about the nature of knowledge, learning, and teaching that generates practical solutions for the everyday problems of teaching." He makes it clear to students that they are responsible for forming their own philosophy, for determining the principles they think are important which will guide what they do in the classroom. Some questions he uses to guide their thinking are:

• What are the proper aims of education? (Not what works, but what purposes are worth working for?)
• What knowledge is worth knowing (teaching)?
• Who should decide what knowledge is worth knowing?
• What is an educated person?
• What kind of relationships should teachers establish with students?
• To what extent should teachers prepare students to be agents for change?
• To what extent should they prepare them to 'fit it'?" 

Before students write answers to these questions, Prof. M leads a discussion which explores all points of view relevant to the issues embedded in them. In these discussions, he tries to persuade them of each of the varying points of view. Then after exposure to these differing views, they write their philosophy of teaching, pointing out principles they believe are important in good teaching, and supporting their positions through reasoned judgment. Professor N (104) Professor N thinks of critical thinking as of primary importance to his instructional objectives. He says that his concept of critical thinking is largely explicit in his thinking. Furthermore, in his concept of critical thinking he explicitly distinguishes critical thinking skills from traits. His responses to the open ended questions are relatively well elaborated. He describes his concept of critical thinking as gathering evidence, evaluating evidence, evaluating the sources of evidence, defining and dissecting the argument or thesis of any given piece of writing for its logic, identifying the points of view and question at issue, evaluating the strengths and weaknesses of an argument. Professor N says that critical thinking involves being aware of one's value judgments and having the willingness to evaluate the evidence before coming to a conclusion. Professor N argues that "content without critical thinking is empty content." He believes that "content without the ability to evaluate it is content that will be mastered only for the length of the course." On the contrary, he says that teachers must organize content so that it is presented logically and so that students some to understand the connections between ideas. In his world history class, he encourages students to think critically about evidence, and what evidence reveals. In this class he uses multiple "primary sources" of information, dating from the time under investigation (e.g. Epic literature, pyramid tombs, Plato's Republic). He provides students with questions they should think through as they read and investigate the information, questions such as "What was the purpose of the author, or what was the purpose of a particular practice? What can this fragment from the past reveal about the culture under investigation? What pieces of information are relevant and why? For his exams, students are asked to develop and then compare arguments on both sides of an issue. They are to determine why certain arguments are more persuasive than others. He says that through his exams, students must demonstrate their ability to consider all points of view which are relevant to an issue, and to document their positions through reasoning. Professor O (45) Professor O considers critical thinking as having primary importance to her instructional objectives. She says that critical thinking is explicit in her thinking, and that it is largely a product of one or more theories of critical thinking. She distinguishes critical thinking skills and traits in her concept of critical thinking. Her responses to the open ended questions, and to follow-up interview questions, were clear and relatively well-elaborated. She understands critical thinking as learning how to think at an in-depth level, to be able to identify and think about problems, situations, and resolutions in a precise and focused manner. She also says that critical thinking means carefully assessing alternatives, figuring out the pros and cons of each. She adds to her definition that critical thinking involves applying reasoning and logic to problems and circumstances in a critical, disciplined and thorough manner. To develop the critical thinking abilities of her students, she has them select a topic to analyze related to a complex problem in education. She then has them critically analyze the different sides to the issue, think through the implications of the possible solutions to the problem, and then come up with recommendations. They are then to turn in the final product (paper) as well as make a presentation to the class which focuses on the process they went through in reaching their final conclusions or recommendations. Furthermore, she says that she tries to combine informal lecture with group discussions, where there is "a lot of give and take." She says that she believes strongly in using Socratic questioning to "draw students out." Professor O requires students to develop their own philosophies of education throughout the course, by focusing on questions such as "What is the ultimate purpose of education? Who is to be educated? Is everyone to be educated? Or are only a privileged few to be educated? She asks students to answer these questions, providing their reasoning for each answer. She asks them to consider alternative ways of answering the question. In preparation for writing their philosophies of education, Professor O asks students to take on roles with respect to particular complex questions related to education, and then debate the issues with one another. She often asks them to take a point of view which differs from their own and to debate from that position. In her classes, professor O requires students to routinely critique each other's work. She does this by having them exchange papers and review one another's papers. She provides guidelines for the standards they are to focus on. Students are to use standards such as: What are the key questions in the paper? How well organized is the paper? How specific are the details? How in-depth are the ideas explored? To what extent are the ideas well thought through? How understandable are the ideas?

Overall Conclusions and Implications

Critical thinking is clearly an honorific phrase in the minds of most teacher educators such that they feel obliged to claim both familiarity with it and commitment to it in their teaching, despite the fact that few have had any in-depth exposure to the research on the concept and most have only a vague understanding of what it is and what is involved in bringing it successfully into instruction. Critical thinking is commonly confused with active involvement in learning (forgetting that active involvement alone is quite compatible with active "mis-learning"). A vague appeal to words from Bloom's Taxonomy (analysis, synthesis, evaluation) is often taken to be demonstrative of knowledge of critical thinking. Even faculty in the CSU, which has a formal policy on critical thinking instruction, is apparently largely unfamiliar with the "definition of critical thinking" and specifications of what minimal conditions for instruction in it are inherent in the policy. It is clear that virtually all departments represented in the study uncritically assume that instruction in critical thinking takes place--without any effort to verify this assumption. In fact, we found no evidence in these interviews of any systematic efforts that have been made to assess instruction for critical thinking within any of the schools of education studied. What is more, there is little understanding of how to assess it--should schools of education desire to do it. Most disturbingly, since the overwhelming majority assumes that the faculty already understand and emphasize critical thinking in their classes, any "in-house" assessment would doubtless be perceived as a pointless "political" process to be carried out with a minimum of effort (but with a clear sense of how to achieve the politically correct answer). In other words, since professors in schools of education assume that they understand critical thinking and how to teach for it, and that they are already successful in teaching their students both, it follows that it will be exceedingly difficult to produce substantial changes in teacher certification programs in these areas. It is clear from the results of the study that we are very far from a state of affairs in which critical thinking is a hallmark of instruction in teacher preparation programs. Present instruction is likely to produce teachers who, on the one hand, are confident that they not only understand critical thinking but also know how to teach for it, but who, in point of fact, understand neither. Many will equate critical thinking with mere active involvement or "cooperative learning." Others will believe that some acquaintance with the terms of Bloom's Taxonomy or Howard Gardner's theory of multiple intellegences is equivalent to understanding critical thinking. Some will equate it with an emphasis on learning styles or with concept maps or some other tool or facet or dimension of learning. Others will equate the whole of critical thinking with some component part of it. Some will therefore emphasize multiple points of view (and take that to be the whole of it). Some will emphasize recognizing one's assumptions. Some will emphasize questioning information sources. Some will emphasize analyzing concepts. But very few will have a comprehensive sense of the whole or a realistic idea of how to cultivate it while teaching the content of a subject or discipline. Using the criteria of the California State Universities and Colleges as an alternative reference point, it is clear that, based on the information we have gathered, the overwhelming number of those certified to teach have little understanding of how to teach so that students will understand "the relationship of language to logic,... (or have) the ability to analyze, criticize, and advocate ideas, to reason inductively and deductively, and to reach factual or judgmental conclusions based on sound inferences drawn from unambiguous statements of knowledge or belief....(or acquire) the ability to distinguish fact from judgment, belief from knowledge, and skills in elementary inductive and deductive processes, including an understanding of the formal and informal fallacies of language and thought." Finally, given the information gathered in this study, it is highly likely that most of those certified to teach have, given present instruction, little understanding of what reasoning is, what assumptions are, what inferences are, what implications are, or what it is to reason with intellectual discipline within a subject field (historically, biologically, psychologically, ...). It appears likely that we are now certifying teachers who not only have little understanding of critical thinking, or how to teach it, but also wrongly and confidently think they do. The end result is that California classrooms are places in which both teachers and students lack explicit knowledge of how to reason in a disciplined way about serious subjects and questions. In the absence of that understanding, one can expect a drifting toward intellectual relativism (i.e., toward the view that all answers sincerely believed and defended are equally good since, as far as they can see, there is no final way to intellectually assess competing answers other than by degree of active involvement in their defense). Subjectivity of response, subjectivity of grading, intellectual undisciplined answers will in all likelihood be unconsciously encouraged. Open-mindedness will be confused with the willingness to accept everyone's answer to a complex question as equally "right" (for them). Given the facts revealed in this study, it is unlikely that students preparing to teach are being instructed in the basic structures of reasoning. Students studying history, biology, and mathematics will not recognize that historians, biologists, and mathematicians equally make assumptions, develop specialized concepts, reason to conclusions, make interpretations of data, trace implications and consequences, define problems, concerns, and issues, and think within a disciplinary frame of reference or point of view. Students studying English, Physics, and Chemistry will not recognize that thinking clearly, accurately, and precisely; thinking deeply, broadly, and logically; are equally important intellectual criteria in every subject. Students will continue to lack any insight into the fact that moral issues and problems require as much disciplined reasoning and clarity of definition as does reasoning in any other domain. Students will graduate, in short, without any plausible semblance of intellectual perspective and discipline. If we are interested in teachers certified in California having a reasonable grounding in the rudiments of critical thinking based on a rich, substantive concept of it, or at least a minimalist, baseline concept, then we have a major task facing us, not the least of which is persuading the majority of the faculty that they do not already know what they confidently assume that they do know.

Limitations of the Study

There were numerous limitations of our study. Some were limitations of time and resources. We were limited in the quantity of people we could interview. We were limited as to the length of the interview. We were limited in the time we had to collect exemplary practices, as well as in the time designated to assembling the report as a whole. There are therefore limitations in the richness of the data collected. With more time and financial support we could have conducted interviews in yet greater depth. We could have engaged in greater study of exemplary practices including, for example, classroom visitations. We could have broadened the net in soliciting exemplary practices and thereby obtained examples from even more disciplines. We could have interviewed teachers in the field, new graduates from teacher education programs, even students at the K-12 level. Very much more might have been done, had there been the time and dollars to do it. 

Nevertheless, despite the obvious limitations of the study, certain patterns in the data we did collect were so consistent across a wide variety of faculty that we believe the study unequivocally establishes some things beyond question, perhaps the main one being that most faculty teaching in teacher education programs have not thought systematically or deeply enough about critical thinking to express a clear, elaborated, and coherent conception of it. It is also beyond question, given the data of the study, that a high percentage of faculty members simply assume that they and their colleagues do understand critical thinking and do effectively teach it. It is also beyond question, from the data we gathered, that it is possible to identify college and university faculty who have devoted some significant portion of their time to developing a clear, well-elaborated, and coherent conception of critical thinking and are actively engaged in developing a variety of effective ways to cultivate critical thinking in their students. What remains to be seen is whether or not we develop the academic and political motivation to pursue a realistic, long-range solution to these problems. It is difficult to predict at this time the degree of resistance and denial that will emerge from education faculty, and the broader education community, to the results of this study. No professional group likes to hear that it has significantly failed to act effectively in fostering a basic value and in furthering an end importantly connected both to its prestige and mission. We can only point to the fact that there are a growing number of faculty nationally who are recognizing the failure of colleges and universities to effectively teach students to think critically and become effective problem solvers. Unfortunately, the history of education does not provide us with a similarly large problem that was solved in the education community by some set of strategies which we could now appropriate, which could be used in developing strategies to rectify the problems clearly documented in the study.

Critical Thinking Advisory Task Force

An Advisory Task Force was appointed consisting of teacher educators, subject matter faculty, and K-12 teachers and administrators to guide the study design, interpretation of data, and policy recommendations.

Why is critical thinking important?

What do lawyers, accountants, teachers, and doctors all have in common?

What is critical thinking?

The Oxford English Dictionary defines critical thinking as “The objective, systematic, and rational analysis and evaluation of factual evidence in order to form a judgment on a subject, issue, etc.” Critical thinking involves the use of logic and reasoning to evaluate available facts and/or evidence to come to a conclusion about a certain subject or topic. We use critical thinking every day, from decision-making to problem-solving, in addition to thinking critically in an academic context!

Why is critical thinking important for academic success?

You may be asking “why is critical thinking important for students?” Critical thinking appears in a diverse set of disciplines and impacts students’ learning every day, regardless of major.

Critical thinking skills are often associated with the value of studying the humanities. In majors such as English, students will be presented with a certain text—whether it’s a novel, short story, essay, or even film—and will have to use textual evidence to make an argument and then defend their argument about what they’ve read. However, the importance of critical thinking does not only apply to the humanities. In the social sciences, an economics major , for example, will use what they’ve learned to figure out solutions to issues as varied as land and other natural resource use, to how much people should work, to how to develop human capital through education. Problem-solving and critical thinking go hand in hand. Biology is a popular major within LAS, and graduates of the biology program often pursue careers in the medical sciences. Doctors use critical thinking every day, tapping into the knowledge they acquired from studying the biological sciences to diagnose and treat different diseases and ailments.

Students in the College of LAS take many courses that require critical thinking before they graduate. You may be asked in an Economics class to use statistical data analysis to evaluate the impact on home improvement spending when the Fed increases interest rates (read more about real-world experience with Datathon ). If you’ve ever been asked “How often do you think about the Roman Empire?”, you may find yourself thinking about the Roman Empire more than you thought—maybe in an English course, where you’ll use text from Shakespeare’s Antony and Cleopatra to make an argument about Roman imperial desire.  No matter what the context is, critical thinking will be involved in your academic life and can take form in many different ways.

The benefits of critical thinking in everyday life

Building better communication.

One of the most important life skills that students learn as early as elementary school is how to give a presentation. Many classes require students to give presentations, because being well-spoken is a key skill in effective communication. This is where critical thinking benefits come into play: using the skills you’ve learned, you’ll be able to gather the information needed for your presentation, narrow down what information is most relevant, and communicate it in an engaging way. 

Typically, the first step in creating a presentation is choosing a topic. For example, your professor might assign a presentation on the Gilded Age and provide a list of figures from the 1870s—1890s to choose from. You’ll use your critical thinking skills to narrow down your choices. You may ask yourself:

• What figure am I most familiar with?
• Who am I most interested in? 
• Will I have to do additional research? 

After choosing your topic, your professor will usually ask a guiding question to help you form a thesis: an argument that is backed up with evidence. Critical thinking benefits this process by allowing you to focus on the information that is most relevant in support of your argument. By focusing on the strongest evidence, you will communicate your thesis clearly.

Finally, once you’ve finished gathering information, you will begin putting your presentation together. Creating a presentation requires a balance of text and visuals. Graphs and tables are popular visuals in STEM-based projects, but digital images and graphics are effective as well. Critical thinking benefits this process because the right images and visuals create a more dynamic experience for the audience, giving them the opportunity to engage with the material.

Presentation skills go beyond the classroom. Students at the University of Illinois will often participate in summer internships to get professional experience before graduation. Many summer interns are required to present about their experience and what they learned at the end of the internship. Jobs frequently also require employees to create presentations of some kind—whether it’s an advertising pitch to win an account from a potential client, or quarterly reporting, giving a presentation is a life skill that directly relates to critical thinking. 

Fostering independence and confidence

An important life skill many people start learning as college students and then finessing once they enter the “adult world” is how to budget. There will be many different expenses to keep track of, including rent, bills, car payments, and groceries, just to name a few! After developing your critical thinking skills, you’ll put them to use to consider your salary and budget your expenses accordingly. Here’s an example:

• You earn a salary of $75,000 a year. Assume all amounts are before taxes.
• 1,800 x 12 = 21,600
• 75,000 – 21,600 = 53,400
• This leaves you with $53,400
• 320 x 12 = 3,840 a year
• 53,400-3,840= 49,560
• 726 x 12 = 8,712
• 49,560 – 8,712= 40,848
• You’re left with $40,848 for miscellaneous expenses. You use your critical thinking skills to decide what to do with your $40,848. You think ahead towards your retirement and decide to put $500 a month into a Roth IRA, leaving $34,848. Since you love coffee, you try to figure out if you can afford a daily coffee run. On average, a cup of coffee will cost you $7. 7 x 365 = $2,555 a year for coffee. 34,848 – 2,555 = 32,293
• You have $32,293 left. You will use your critical thinking skills to figure out how much you would want to put into savings, how much you want to save to treat yourself from time to time, and how much you want to put aside for emergency funds. With the benefits of critical thinking, you will be well-equipped to budget your lifestyle once you enter the working world.

Enhancing decision-making skills

Choosing the right university for you.

One of the biggest decisions you’ll make in your life is what college or university to go to. There are many factors to consider when making this decision, and critical thinking importance will come into play when determining these factors.

Many high school seniors apply to colleges with the hope of being accepted into a certain program, whether it’s biology, psychology, political science, English, or something else entirely. Some students apply with certain schools in mind due to overall rankings. Students also consider the campus a school is set in. While some universities such as the University of Illinois are nestled within college towns, New York University is right in Manhattan, in a big city setting. Some students dream of going to large universities, and other students prefer smaller schools. The diversity of a university’s student body is also a key consideration. For many 17- and 18-year-olds, college is a time to meet peers from diverse racial and socio-economic backgrounds and learn about life experiences different than one’s own.

With all these factors in mind, you’ll use critical thinking to decide which are most important to you—and which school is the right fit for you.

Develop your critical thinking skills at the University of Illinois

At the University of Illinois, not only will you learn how to think critically, but you will put critical thinking into practice. In the College of LAS, you can choose from 70+ majors where you will learn the importance and benefits of critical thinking skills. The College of Liberal Arts & Sciences at U of I offers a wide range of undergraduate and graduate programs in life, physical, and mathematical sciences; humanities; and social and behavioral sciences. No matter which program you choose, you will develop critical thinking skills as you go through your courses in the major of your choice. And in those courses, the first question your professors may ask you is, “What is the goal of critical thinking?” You will be able to respond with confidence that the goal of critical thinking is to help shape people into more informed, more thoughtful members of society.

With such a vast representation of disciplines, an education in the College of LAS will prepare you for a career where you will apply critical thinking skills to real life, both in and outside of the classroom, from your undergraduate experience to your professional career. If you’re interested in becoming a part of a diverse set of students and developing skills for lifelong success, apply to LAS today!

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment. Political and business leaders endorse its importance.

For details on this history, see the Supplement on History .

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o'clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68-69; 1933: 91-92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot's position, it must appear to project far out in front of the boat. Morevoer, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69-70; 1933: 92-93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond line from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009), others on the resulting judgment (Facione 1990a), and still others on the subsequent emotive response (Siegel 1988).

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in frequency in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the frequency of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Critical thinking dispositions can usefully be divided into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started) (Facione 1990a: 25). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), and Black (2012).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work.

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? Abrami et al. (2015) found that in the experimental and quasi-experimental studies that they analyzed dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), and Bailin et al. (1999b).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.

Critical thinking definition

Critical thinking, as described by Oxford Languages, is the objective analysis and evaluation of an issue in order to form a judgement.

Active and skillful approach, evaluation, assessment, synthesis, and/or evaluation of information obtained from, or made by, observation, knowledge, reflection, acumen or conversation, as a guide to belief and action, requires the critical thinking process, which is why it's often used in education and academics.

Some even may view it as a backbone of modern thought.

However, it's a skill, and skills must be trained and encouraged to be used at its full potential.

People turn up to various approaches in improving their critical thinking, like:

• Developing technical and problem-solving skills
• Engaging in more active listening
• Actively questioning their assumptions and beliefs
• Seeking out more diversity of thought
• Opening up their curiosity in an intellectual way etc.

Is critical thinking useful in writing?

Critical thinking can help in planning your paper and making it more concise, but it's not obvious at first. We carefully pinpointed some the questions you should ask yourself when boosting critical thinking in writing:

• What information should be included?
• Which information resources should the author look to?
• What degree of technical knowledge should the report assume its audience has?
• What is the most effective way to show information?
• How should the report be organized?
• How should it be designed?
• What tone and level of language difficulty should the document have?

Usage of critical thinking comes down not only to the outline of your paper, it also begs the question: How can we use critical thinking solving problems in our writing's topic?

Let's say, you have a Powerpoint on how critical thinking can reduce poverty in the United States. You'll primarily have to define critical thinking for the viewers, as well as use a lot of critical thinking questions and synonyms to get them to be familiar with your methods and start the thinking process behind it.
