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.

How to Write a Thesis Statement | 4 Steps & Examples
Published on January 11, 2019 by Shona McCombes . Revised on August 15, 2023 by Eoghan Ryan.
A thesis statement is a sentence that sums up the central point of your paper or essay . It usually comes near the end of your introduction .
Your thesis will look a bit different depending on the type of essay you’re writing. But the thesis statement should always clearly state the main idea you want to get across. Everything else in your essay should relate back to this idea.
You can write your thesis statement by following four simple steps:
- Start with a question
- Write your initial answer
- Develop your answer
- Refine your thesis statement

A thesis statement summarizes the central points of your essay. It is a signpost telling the reader what the essay will argue and why.
The best thesis statements are:
- Concise: A good thesis statement is short and sweet—don’t use more words than necessary. State your point clearly and directly in one or two sentences.
- Contentious: Your thesis shouldn’t be a simple statement of fact that everyone already knows. A good thesis statement is a claim that requires further evidence or analysis to back it up.
- Coherent: Everything mentioned in your thesis statement must be supported and explained in the rest of your paper.

The thesis statement generally appears at the end of your essay introduction or research paper introduction .
The spread of the internet has had a world-changing effect, not least on the world of education. The use of the internet in academic contexts and among young people more generally is hotly debated. For many who did not grow up with this technology, its effects seem alarming and potentially harmful. This concern, while understandable, is misguided. The negatives of internet use are outweighed by its many benefits for education: the internet facilitates easier access to information, exposure to different perspectives, and a flexible learning environment for both students and teachers.
You should come up with an initial thesis, sometimes called a working thesis , early in the writing process . As soon as you’ve decided on your essay topic , you need to work out what you want to say about it—a clear thesis will give your essay direction and structure.
You might already have a question in your assignment, but if not, try to come up with your own. What would you like to find out or decide about your topic?
For example, you might ask:
After some initial research, you can formulate a tentative answer to this question. At this stage it can be simple, and it should guide the research process and writing process .

Now you need to consider why this is your answer and how you will convince your reader to agree with you. As you read more about your topic and begin writing, your answer should get more detailed.
In your essay about the internet and education, the thesis states your position and sketches out the key arguments you’ll use to support it.
The negatives of internet use are outweighed by its many benefits for education because it facilitates easier access to information.
In your essay about braille, the thesis statement summarizes the key historical development that you’ll explain.
The invention of braille in the 19th century transformed the lives of blind people, allowing them to participate more actively in public life.
A strong thesis statement should tell the reader:
- Why you hold this position
- What they’ll learn from your essay
- The key points of your argument or narrative
The final thesis statement doesn’t just state your position, but summarizes your overall argument or the entire topic you’re going to explain. To strengthen a weak thesis statement, it can help to consider the broader context of your topic.
These examples are more specific and show that you’ll explore your topic in depth.
Your thesis statement should match the goals of your essay, which vary depending on the type of essay you’re writing:
- In an argumentative essay , your thesis statement should take a strong position. Your aim in the essay is to convince your reader of this thesis based on evidence and logical reasoning.
- In an expository essay , you’ll aim to explain the facts of a topic or process. Your thesis statement doesn’t have to include a strong opinion in this case, but it should clearly state the central point you want to make, and mention the key elements you’ll explain.

A thesis statement is a sentence that sums up the central point of your paper or essay . Everything else you write should relate to this key idea.
The thesis statement is essential in any academic essay or research paper for two main reasons:
- It gives your writing direction and focus.
- It gives the reader a concise summary of your main point.
Without a clear thesis statement, an essay can end up rambling and unfocused, leaving your reader unsure of exactly what you want to say.
Follow these four steps to come up with a thesis statement :
- Ask a question about your topic .
- Write your initial answer.
- Develop your answer by including reasons.
- Refine your answer, adding more detail and nuance.
The thesis statement should be placed at the end of your essay introduction .

Thesis Statements
What this handout is about.
This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.
Introduction
Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.
What is a thesis statement?
A thesis statement:
- tells the reader how you will interpret the significance of the subject matter under discussion.
- is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
- directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
- makes a claim that others might dispute.
- is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.
If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)
How do I create a thesis?
A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.
Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .
How do I know if my thesis is strong?
If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :
- Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
- Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
- Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
- Does my thesis pass the “So what?” test? If a reader’s first response is likely to be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
- Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
- Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.
Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:
Social media impacts public awareness in both positive and negative ways.
You can use the questions above to help you revise this general statement into a stronger thesis.
- Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
- Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
- Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
- Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
- Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?
After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:
Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.
This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.
Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:
Mark Twain’s Huckleberry Finn is a great American novel.
You begin to analyze your thesis:
- Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.
Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:
In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.
- Do I answer the question? Yes!
- Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
- Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
- Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
- Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”
After examining the evidence and considering your own insights, you write:
Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.
This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

How to Write a Persuasive Essay in 6 Steps
A persuasive essay is defined by two purposes: to convince the audience to agree with the speaker’s position on a debatable issue and to inspire listeners to take action. In order to succeed, the speaker must forge a relationship with the audience, while appealing to their intellect and emotions. Let’s look at six steps to writing an excellent persuasive essay.
1. Choose a debatable issue about which you have strong feelings and a definite position.
A debatable issue is one that generates conflicting opinions and points of view; it also may generate strong personal or professional feelings as to how it should be addressed. A persuasive essay is likely to be more effective if you invest your time and effort in writing about an issue that is important to you, perhaps one that you relate to personally.
2. Research all sides of the issue and take notes.
Once you have chosen an issue for your essay, research conflicting views about it. Take notes over information that supports your position on the issue: facts, examples, statistics, anecdotes, and quotations from experts and/or reliable studies. Record the sources of the information to establish its reliability. Also, take notes over information that supports the strongest argument against your position on the issue.
3. Draft a thesis statement for your essay.
Like most essays, a persuasive essay needs a thesis statement: a sentence that clearly states what you will explain and support in the essay. Write a thesis that clearly states your position on the issue.
4. Create a working outline.
A working outline is not detailed. Referring to your notes, create a 3-part working outline that lists 2 of the strongest arguments in favor of your position and the strongest argument against it.
5. Draft the introduction, main body, and conclusion of your essay.
In drafting your essay, keep in mind the objectives to achieve in each part. Also, incorporate rhetorical devices, imagery, and figurative language throughout the text.
Introduction: To arouse the interest of the audience, use one or more of these methods.
- Begin with an anecdote that relates to the subject of the essay; it can be an anecdote from your personal experience or one you have heard or read from another source.
- Begin with historical or factual information of interest regarding the subject.
- Begin with a quotation that relates to the subject. Quotations from history, literature, or contemporary figures can all be effective; identify the source of the quotation.
Develop the introduction by identifying the general subject of your essay and the specific issue at hand; acknowledge that the issue generates disagreement, as views regarding it often conflict.
Conclude the introduction with your thesis, stating your position on the issue clearly and concisely.
Main Body: Refer to your working outline while writing the main body of your essay. Draft a main body paragraph to address each of the three parts of the outline. Since the working outline includes two arguments supporting your position and one opposing it, the main body may consist of three paragraphs; however, if more than one paragraph is required to thoroughly address a part of your outline, by all means, write it. Refer to your research notes and the list of rhetorical devices while developing each paragraph.
Conclusion: The final paragraph should indicate to listeners that your essay is reaching an end.
- Restate the issue and your position regarding it.
- Briefly sum up your two arguments in favor of your position.
- Explain what will happen if your position is not adopted and why the resulting consequences are important to the audience.
- Point out actions that should be taken in addressing the issue to avoid serious consequences.
The final sentence of the conclusion should leave listeners with something to think about. A powerful, thought-provoking quotation, a vivid image, or a final rhetorical question—asked and answered—will provide a sense of closure, while emphasizing the validity of your essay.
6. Review the structure and content of the essay, and revise the text to make it more effective and convincing.
After reviewing and revising the text of your essay, you should be able to answer “yes” to these questions:
Is there a paragraph of introduction?
- Have you engaged the interest of the audience in some way?
- Have you established your own voice in the essay and created a bond between you and your listeners?
- Have you identified the topic and the specific issue of your essay?
- Does the paragraph end with a thesis statement that clearly states your position on the issue?
Does the main body consist of at least 3 paragraphs?
- In the first main body paragraph, have you stated the strongest argument against your position on the issue? Have you refuted the argument with various types of specific evidence?
- In the second main body paragraph, have you presented your first argument in favor of your position? Have you supported your argument with various types of specific evidence?
- In the third main body paragraph, have you presented a stronger argument in favor of your position, the best argument you can present? Have you supported it with various types of specific evidence?
- Throughout the main body paragraphs, have you included appeals to ethos, pathos, and logos?
Is there a paragraph of conclusion?
- Have you restated the issue and your position on it?
- Have you summed up your two arguments in favor of your position?
- Have you explained what will happen if your position is not adopted and why the resulting consequences are important to the audience?
- Have you pointed out actions that should be taken in addressing the issue to avoid serious consequences?
- Does the conclusion give listeners a sense of closure and leave them with something to think about?
Does the text of your essay employ numerous rhetorical devices?
As you read your essay aloud, have you provided transition words and phrases to move smoothly from one part of a paragraph to another and from one paragraph to the next?
Do you think your essay is persuasive and will hold the attention of the audience? (If not, why not? What would make it more persuasive and engaging?)

One of the most important elements of your persuasive essay is your thesis statement, which should tell readers exactly what your stance encompasses. Without a forceful thesis, you won’t be able to deliver an effective argument.
Persuasive writing begins with a writer forming their own opinion on a topic, which they then attempt to convince their reader of this opinion by walking them through a number of logical and ethical arguments.
