Developing Strong Thesis Statements

Welcome to the Purdue OWL

These OWL resources will help you develop and refine the arguments in your writing.

The thesis statement or main claim must be debatable

An argumentative or persuasive piece of writing must begin with a debatable thesis or claim. In other words, the thesis must be something that people could reasonably have differing opinions on. If your thesis is something that is generally agreed upon or accepted as fact then there is no reason to try to persuade people.

Example of a non-debatable thesis statement:

This thesis statement is not debatable. First, the word pollution implies that something is bad or negative in some way. Furthermore, all studies agree that pollution is a problem; they simply disagree on the impact it will have or the scope of the problem. No one could reasonably argue that pollution is unambiguously good.

Example of a debatable thesis statement:

This is an example of a debatable thesis because reasonable people could disagree with it. Some people might think that this is how we should spend the nation's money. Others might feel that we should be spending more money on education. Still others could argue that corporations, not the government, should be paying to limit pollution.

Another example of a debatable thesis statement:

In this example there is also room for disagreement between rational individuals. Some citizens might think focusing on recycling programs rather than private automobiles is the most effective strategy.

The thesis needs to be narrow

Although the scope of your paper might seem overwhelming at the start, generally the narrower the thesis the more effective your argument will be. Your thesis or claim must be supported by evidence. The broader your claim is, the more evidence you will need to convince readers that your position is right.

Example of a thesis that is too broad:

There are several reasons this statement is too broad to argue. First, what is included in the category "drugs"? Is the author talking about illegal drug use, recreational drug use (which might include alcohol and cigarettes), or all uses of medication in general? Second, in what ways are drugs detrimental? Is drug use causing deaths (and is the author equating deaths from overdoses and deaths from drug related violence)? Is drug use changing the moral climate or causing the economy to decline? Finally, what does the author mean by "society"? Is the author referring only to America or to the global population? Does the author make any distinction between the effects on children and adults? There are just too many questions that the claim leaves open. The author could not cover all of the topics listed above, yet the generality of the claim leaves all of these possibilities open to debate.

Example of a narrow or focused thesis:

In this example the topic of drugs has been narrowed down to illegal drugs and the detriment has been narrowed down to gang violence. This is a much more manageable topic.

We could narrow each debatable thesis from the previous examples in the following way:

Narrowed debatable thesis 1:

This thesis narrows the scope of the argument by specifying not just the amount of money used but also how the money could actually help to control pollution.

Narrowed debatable thesis 2:

This thesis narrows the scope of the argument by specifying not just what the focus of a national anti-pollution campaign should be but also why this is the appropriate focus.

Qualifiers such as " typically ," " generally ," " usually ," or " on average " also help to limit the scope of your claim by allowing for the almost inevitable exception to the rule.

Types of claims

Claims typically fall into one of four categories. Thinking about how you want to approach your topic, or, in other words, what type of claim you want to make, is one way to focus your thesis on one particular aspect of your broader topic.

Claims of fact or definition: These claims argue about what the definition of something is or whether something is a settled fact. Example:

Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:

Claims about value: These are claims made of what something is worth, whether we value it or not, how we would rate or categorize something. Example:

Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:

Which type of claim is right for your argument? Which type of thesis or claim you use for your argument will depend on your position and knowledge of the topic, your audience, and the context of your paper. You might want to think about where you imagine your audience to be on this topic and pinpoint where you think the biggest difference in viewpoints might be. Even if you start with one type of claim you probably will be using several within the paper. Regardless of the type of claim you choose to utilize it is key to identify the controversy or debate you are addressing and to define your position early on in the paper.

Argument and Persuasion: Structuring and Writing an Argument Essay

• Find Articles
• Structuring and Writing an Argument Essay

Page Overview

This page deals with the process of writing the argument: planning, structuring, strategies, writing, revision.

Pre-Writing Considerations

There are things that should be given some attention before you begin writing your argument.  Thoughtful planning in the pre-writing stage increases the chances of your argument successfully convincing your audience.  A well-executed piece of writing should be unified, coherent, and complete.

unified = the paper presents only a single idea or, if more than one idea, one point is made the principal one and the others are subordinated to it 

coherent = the discussion flows smoothly and logically and is easy for the reader to follow; trying to make sense of the writing does not become an ordeal

complete = everything that should be said, has been said; no questions are left in the mind of the reader

Achieving a coherent, complete, unified piece of Argumentative Writing 

1.  Clearly state the argument/proposition of your essay.

2.  Analyze the proposition.  First, jot down points of conflict between your view and the opposing view.  Second, think over your jottings and try to decide which points are the issues on which your argument should hinge.  Third, arrange your jottings in order to give unity and coherence to your essay.

3.  Write a paragraph (or more if necessary) on each point of conflict.  (This step will have some variation, depending on whether you are using the block or point pattern of organization.)

4.  Analyze and evaluate what you have written to see whether (a) the evidence seems reliable and (b) the reasoning free of fallacies.

5.  Establish effective transitions between the discussions of the various points ( coherence ), keeping in mind that your objective is to connect each point to the main contention of your theme, the main proposition.

6.  Think of your introduction.  What makes the topic worth arguing about now (purpose)?  (NOTE:  Your topic should be broad enough to interest a large number of people, yet narrow enough that you can focus and manage the discussion.)  What kind of people are you writing for (audience)?  Can you depend on an interested and sympathetic hearing, or must you strive to gain attention and win people over?  If you have to gain attention, how will you go about it?  After you have thought about these things and written a first draft of your introduction, do you think it necessary to go back and revise the discussion in the body of your essay to make it better adapted to your audience?

7.  Treat your conclusion as the last impression you will leave on your readers.  Do you return here to your key point (your thesis), showing how your whole argument essay bears on and supports it?  Do you leave your readers with a positive impression of your effort, even if you cannot be sure of having totally convinced them by reason?

Pattern Outlines for an Argument Essay

(Based on https://apps.spokane.edu/.../Summary%20Response%20Essay%20Assignment.pdf

     In the context of argument, "pro" means agree/support, and "con" means disagree/oppose.   Whether you structure your argument to follow the block style or point-by-point pattern, the three principal components of presentation, support, and refutation must be included.  A point-by-point structure probably will be easier to follow, as the block style creates some separation between the "pro" and "con" sides of an argument which may require readers to do some up-and-down "scrolling" of the text.

Purdue Owl - Organizing Your Expository/Persuasive Essay

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue (http://owl.english.purdue.edu/). When printing this page, you must include the entire legal notice at bottom.

Organizing You Expository/Persuasive Essay

How can I effectively present my argument?

Use an organizational structure that arranges the argument in a way that will make sense to the reader. The Toulmin Method of logic is a common and easy to use formula for organizing an argument.

The basic format for the Toulmin Method is as follows:

Claim: The overall thesis the writer will argue for.

Data: Evidence gathered to support the claim.

Warrant (also referred to as a bridge): Explanation of why or how the data supports the claim, the underlying assumption that connects your data to your claim.

Backing (also referred to as the foundation): Additional logic or reasoning that may be necessary to support the warrant.

Counterclaim: A claim that negates or disagrees with the thesis/claim.

Rebuttal: Evidence that negates or disagrees with the counterclaim.

Including a well thought out warrant or bridge is essential to writing a good argumentative essay or paper. If you present data to your audience without explaining how it supports your thesis they may not make a connection between the two or they may draw different conclusions.

Don't avoid the opposing side of an argument. Instead, include the opposing side as a counterclaim. Find out what the other side is saying and respond to it within your own argument. This is important so that the audience is not swayed by weak, but unrefuted, arguments. Including counterclaims allows you to find common ground with more of your readers. It also makes you look more credible because you appear to be knowledgeable about the entirety of the debate rather than just being biased or uniformed. You may want to include several counterclaims to show that you have thoroughly researched the topic.

Claim: Hybrid cars are an effective strategy to fight pollution.

Data1: Driving a private car is a typical citizen's most air polluting activity.

Warrant 1: Because cars are the largest source of private, as opposed to industry produced, air pollution switching to hybrid cars should have an impact on fighting pollution.

Data 2: Each vehicle produced is going to stay on the road for roughly 12 to 15 years.

Warrant 2: Cars generally have a long lifespan, meaning that a decision to switch to a hybrid car will make a long-term impact on pollution levels.

Data 3: Hybrid cars combine a gasoline engine with a battery-powered electric motor.

Warrant 3: This combination of technologies means that less pollution is produced. According to ineedtoknow.org "the hybrid engine of the Prius, made by Toyota, produces 90 percent fewer harmful emissions than a comparable gasoline engine."

Counterclaim: Instead of focusing on cars, which still encourages a culture of driving even if it cuts down on pollution, the nation should focus on building and encouraging use of mass transit systems.

Rebuttal: While mass transit is an environmentally sound idea that should be encouraged, it is not feasible in many rural and suburban areas, or for people who must commute to work; thus hybrid cars

Additional Information on Organization and Content of the Expository/Persuasive Essay from Other Areas of Purdue OWL

The structure of the argumentative/expository/persuasive essay is held together by the following:

A clear, concise, and defined thesis statement that occurs in the first paragraph of the essay.

In the first paragraph of an argument essay, students should set the context by reviewing the topic in a general way. Next the author should explain why the topic is important (exigence) or why readers should care about the issue. Lastly, students should present the thesis statement. It is essential that this thesis statement be appropriately narrowed to follow the guidelines set forth in the assignment. If the student does not master this portion of the essay, it will be quite difficult to compose an effective or persuasive essay.

Clear and logical transitions between the introduction, body, and conclusion.

Transitions are the mortar that holds the foundation of the essay together. Without logical progression of thought, the reader is unable to follow the essay’s argument, and the structure will collapse. Transitions should wrap up the idea from the previous section and introduce the idea that is to follow in the next section.

Body paragraphs that include evidential support.

Each paragraph should be limited to the discussion of one general idea. This will allow for clarity and direction throughout the essay. In addition, such conciseness creates an ease of readability for one’s audience. It is important to note that each paragraph in the body of the essay must have some logical connection to the thesis statement in the opening paragraph. Some paragraphs will directly support the thesis statement with evidence collected during research. It is also important to explain how and why the evidence supports the thesis (warrant).

However, argumentative/expository/persuasive essays should also consider and explain differing points of view regarding the topic. Depending on the length of the assignment, students should dedicate one or two paragraphs of the essay to discussing conflicting opinions on the topic. Rather than explaining how these differing opinions are wrong outright, students should note how opinions that do not align with their thesis might not be well informed or how they might be out of date.

A conclusion that does not simply restate the thesis, but readdresses it in light of the evidence provided.

It is at this point of the essay that students may begin to struggle. This is the portion of the essay that will leave the most immediate impression on the mind of the reader. Therefore, it must be effective and logical. Do not introduce any new information into the conclusion; rather, synthesize the information presented in the body of the essay. Restate why the topic is important, review the main points, and review your thesis.

A Complete Argument

Perhaps it is helpful to think of an essay in terms of a conversation or debate with a classmate. If I were to discuss the cause of World War II and its current effect on those who lived through the tumultuous time, there would be a beginning, middle, and end to the conversation. In fact, if I were to end the argument in the middle of my second point, questions would arise concerning the current effects on those who lived through the conflict. Therefore, the argumentative essay must be complete, and logically so, leaving no doubt as to its intent or argument.

Composition Writing Studio

Argumentative essay/commentary.

From the University of Purdue’s Online Writing Lab (http://owl.english.purdue.edu/owl/resource/685/05/):

The argumentative essay is a genre of writing that requires the student to investigate a topic, collect, generate, and evaluate evidence, and establish a position on the topic in a concise manner.

Argumentative essay assignments generally call for extensive research of literature or previously published material. Argumentative assignments may also require empirical research where the student collects data through interviews, surveys, observations, or experiments. Detailed research allows the student to learn about the topic and to understand different points of view regarding the topic so that s/he may choose a position and support it with the evidence collected during research. Regardless of the amount or type of research involved, argumentative essays must establish a clear thesis and follow sound reasoning.

3 Purdue University Essay Examples

Home of the Boilermakers, Purdue University was established in 1869 and is steeped in history and tradition. From the first 39 students to attend in 1874, to over 33,000 in attendance today, Purdue is matched in tradition only by innovation. Known for its world-class faculty, curricula, and facilities, Purdue attracts many future engineers.

As it is a selective university, you will need a strong application to stand out. A crucial aspect lies in your essays. To get some inspiration for your Purdue essays, we will be sharing three essays by real students who applied to Purdue in this post. We will also go over what they did well and where they could’ve improved. 

Please note: Looking at examples of real essays students have submitted to colleges can be very beneficial to get inspiration for your essays. You should never copy or plagiarize from these examples when writing your own essays. Colleges can tell when an essay isn’t genuine and will not view students favorably if they plagiarized. 

Read our Purdue essay breakdown to get a comprehensive overview of this year’s supplemental prompts. 

Essay Example #1

Prompt: Briefly discuss your reasons for pursuing the major you have selected (100 words)

To most Gen Z, life without computers and smartphones is like life without food: it’s impossible. However, I only started to appreciate the work behind the scenes (and screens) in the summer of 9th grade, when I created a small chatting program to exchange jokes with my sister in the next room. Through programming, I have found a clear and compelling way to reach the world beyond my fingertips. By majoring in computer science, I hope to build a solid foundation in AI, algorithms, UX design and more, with which I’ll help bring society a new generation of digital food.

What the Essay Did Well

This essay is short and sweet; every sentence is intentional and conveys a new idea clearly and concisely. Comparing their generation’s reliance on technology to “ life without food ” speaks volumes more than the three words it takes up. They simply explain what they did and why without any extraneous fluff or flowery language: “ I created a small chatting program to exchange jokes with my sister in the next room. ” Getting creative with your prose is great for a longer essay, but this is not the time or place, and this student understood that. They also get straight to the point when discussing what they hope to gain and achieve from a degree in computer science—another plus.

Despite the limited space, this student still manages to work in some of their personality. The analogy of smartphones being as crucial as food is a humorous example of hyperbole that helps humanize the student.  The phrase “ behind the scenes (and screens) ” is another way of them expressing their playful side while also adding a rhyme to make the essay more interesting. Including these little crumbs with humor, coupled with the knowledge they learned to program to share jokes, makes the student come across as a fun person admissions officers would want on their campus.

What Could Be Improved

Although the opening line about Gen Z is a chance for the student to inject some of their personality, in reality it is not the best use of space. As we said above, every word counts in an essay this short, and although the observation about Gen Z did contribute to the essay, it’s not as crucial to include as additional details about the student.

They could have kept the analogy to food, but instead of generalizing to all of Gen Z, this student should have made themselves the focus of the sentence. For example, they could say something like this: “ At this point my phone is a permanent appendage of my hand; life without it is like life without food. ” This sentence focuses the attention on the student right from the beginning, telling us about their phone addiction rather than everyone else’s.

Essay Example #2

How much duct tape would my boat need to stay afloat?

I will never forget my first Do-It-Yourself Project of building a boat with cardboard. While the outcome of the project was bitter-sweet as my boat sank, my passion for engineering surfaced. Subsequently, I voyaged across countless pursuits until I reached an epiphany while developing a customized voice assistant for an enterprise; I was fascinated by the multifaceted applicability of technology. Hence, I intend to pursue Computer Engineering because the skills from this major will enable me to pursue my widespread goals of lobbying for technological advancements in under-developed societies.

Starting the essay with a question is a great way to catch the reader’s attention in a short amount of space. Right off the bat, we are asking ourselves why are they using duct tape, what’s the boat for, how much duct tape do they need,  all of which get us engaged and excited for what is to come.

The student also does a nice job of incorporating sailing-related language with lines like “ my passion for engineering surfaced ” and “ I voyaged across countless pursuits. ” This is a creative way of linking the main points of their essay with their anecdote.

The student’s realizations are a bit underdeveloped. They don’t explain how they realized the “ multifaceted applicability of technology ” or why exactly they want to lobby “ for technological advancements in under-developed countries. ” They could’ve perhaps been better-served by eliminating the boat anecdote and beginning with the voice assistant story, which would allow them to explain their realization and goals. 

A common mistake students make with this prompt is that they think they have to include the very moment they got interested in the major. You certainly can use this technique, but it may not always be the best way to approach this essay, especially when there is such limited space. Instead of starting with the introduction, students should first focus on writing the reasons they like the major and what they hope to accomplish with it, and find a story or moment that flows with these points.

Essay Example #3

Prompt: How will opportunities at Purdue support your interests, both in and out of the classroom? (100 words)

The Computer Engineering course at Purdue has a dynamic combination of fundamental courses and enthralling electives such as ‘Engineering Environmental Sustainability’, allowing me to apply my engineering proficiency to resolve complex global issues such as technological disparity. Furthermore, by joining the Engineers Without Borders – Purdue organization, I will gain first-hand experience in tackling real-world humanitarian problems and push my intellectual ability to higher stakes. Having followed EWB- Purdue’s pioneering Bolivia project, I aspire to contribute in both the Technical and the Leadership team. Hence, Purdue is the best institution for me to grow as an enthusiastic humanitarian engineer. 

Right off the bat, the student is specifically noting courses the school offers that they are eager to take. This is great! They show that they’ve been following a specific organization within the school, and already have ideas as to how they could contribute. They really specified why they wanted to attend the school, and personalized the essay accordingly. 

This student also chose two opportunities at Purdue that seamlessly fit into their future career. They want to be a humanitarian engineer, so discussing a class about environmental sustainability and an organization that creates solutions to humanitarian issues around the world is a great way to demonstrate their affinity to their career throughout the essay. When they tell us their career aspirations at the very end of the essay, it makes perfect sense to the reader based on the 100 preceding words we just read.

The main issues in this essay come from minor grammatical mistakes that could confuse the reader. For example, the first sentence covers too much ground: The Computer Engineering course at Purdue has a dynamic combination of fundamental courses and enthralling electives such as ‘Engineering Environmental Sustainability’, allowing me to apply my engineering proficiency to resolve complex global issues such as technological disparity. Instead, the reader should separate these ideas into two sentences. In the first sentence, the student can explain the courses they are interested in, and the second can give reasons why and explain what the student’s career goals are. Overall, it very clearly addresses the prompt, shows the student has done their research, and shows their ambitions after graduation. It is very well done.

Writing an Informative Essay

Informative essays engage readers with new, interesting, and often surprising facts and details about a subject. Informative essays are educational; readers expect to learn something new from them. In fact, much of the reading and writing done in college and the workplace is informative. From textbooks to reports to tutorials like this one, informative writing imparts important and useful information about a topic.

This tutorial refers to the sample informative outline and final essay written by fictional student Paige Turner.

Reasons to Write Informatively

Your purpose for writing and the audience for whom you are writing will impact the depth and breadth of information you provide, but all informative writing aims to present a subject without opinions or bias. Some common reasons to write informatively are to

• report findings that an audience would find interesting,
• present facts that an audience would find useful, and
• communicate information about a person, place, event, issue, or change that would improve an audience’s understanding.

Characteristics of Informative Essays

Informative essays present factual information and do not attempt to sway readers’ opinions about it. Other types of academic and workplace writing do try to influence readers’ opinions:

• Expository essays aim to expose a truth about an issue in order to influence how readers view the issue.
• Persuasive essays aim to influence readers’ opinions, so they will adopt a particular position or take a certain course of action.

Expository and persuasive essays make “arguments.” The only argument an informative essay makes is that something exists, did exist, is happening, or has happened, and the point of the essay is not to convince readers of this but to tell them about it.

• Informative essays seek to enlighten and educate readers, so they can make their own educated opinions and decisions about what to think and how to act.

Strategies for Writing Informatively

Informative essays provide useful information such as facts, examples, and evidence from research in order to help readers understand a topic or see it more clearly. While informative writing does not aim to appeal emotionally to readers in order to change their opinions or behaviors, informative writing should still be engaging to read. Factual information is not necessarily dry or boring. Sometimes facts can be more alarming than fiction!

Writers use various strategies to engage and educate readers. Some strategies include

• introducing the topic with an alarming fact or arresting image;
• asserting what is true or so about the subject in a clear thesis statement;
• organizing the paragraphs logically by grouping related information;
• unifying each paragraph with a topic sentence and controlling idea;
• developing cohesive paragraphs with transition sentences;
• using precise language and terminology appropriate for the topic, purpose, and audience; and
• concluding with a final idea or example that captures the essay’s purpose and leaves a lasting impression.

Five Steps for Getting Started

1. Brainstorm and choose a topic.

• Sample topic : The opioid epidemic in the United States.
• The opiod epidemic or even opiod addiction would would be considered too broad for a single essay, so the next steps aim to narrow this topic down.

2. Next, write a question about the topic that you would like to answer through research.

• Sample question : What major events caused the opioid crisis in the United States?
• This question aims to narrow the topic down to causes of the epidemic in the US.

3. Now go to the Purdue Global Library to find the answers to your research question.

As you begin reading and collecting sources, write down the themes that emerge as common answers. Later, in step four, use the most common answers (or the ones you are most interested in writing and discussing) to construct a thesis statement.

• Sample answers: aggressive marketing, loopholes in prescription drug provider programs, and economic downturn.

4. Next, provide purpose to your paper by creating a thesis statement.

The thesis attempts to frame your research question. The sample thesis below incorporates three of the more common answers for the research question from step two: What caused the opioid crisis in the United States?

• Thesis Statement : Aggressive marketing, loopholes in prescription drug provider programs, and economic downturn contributed to the current opioid crisis in the United States.
• Writing Tip : For additional help with thesis statements, please visit our Writing a Thesis Statement article. For help with writing in 3rd person, see our article on Formal Vs. Informal Writing .

5. Now follow each numbered step in the “Suggested Outline Format and Sample” below.

Sample answers have been provided for “I. Introduction” and “II. First Cause.” A complete sample outline can be seen here. A complete sample informative essay can be seen here.

Suggested Outline Format and Sample

I. INTRODUCTION

A. First provide a topic sentence that introduces the main topic: Sample topic sentence : There is a current prescription pain medication addiction and abuse epidemic possibly caused by an excessive over prescription of these medications.

B. Now provide a couple sentences with evidence to support the main topic: Sample sentence one with evidence to support the main topic : According to Dr. Nora Volkow, Director of National Institute on Drug Abuse (NIDA), in testimony before the 115th Congress, “In 2016, over 11 million Americans misused prescription opioids … and 2.1 million had an opioid use disorder due to prescription opioids” (Federal Efforts to Combat the Opioid Crisis, 2017, p. 2).

C. Sample sentence two with evidence to support the main topic : Volkow indicated “more than 300,000 Americans have died of an opioid overdose” since 2013 (Federal Efforts to Combat the Opioid Crisis, 2017, p.2).

D. Sample sentence three with evidence to support the main topic : According to Perez-Pena (2017), the Center for Disease Control and Prevention reported more than 25,000 people in the United States died in 2015 from overdosing on opioids Fentanyl, Oxycodone, and Hydrocodone.

E. Toward the end of the introduction, include your thesis statement written in the 3rd-person point-of-view: Sample thesis statement : Potential solutions to the growing opioid epidemic may be illuminated by examining how opioid addiction is triggered through aggressive pharmaceutical marketing, how opioid addiction manifests among prescribed patients, and how economic downturns play a role in the increase of opioid addiction.

F. Write down the library sources you can use in this introductory paragraph to help support the main topic.

• Federal Efforts to Combat the Opioid Crisis, 2017
• Perez-Pena, 2017
• Writing Tip : For more help writing an introduction, please refer to this article on introductions and conclusions .

II. FIRST CAUSE
