Thesis Statements Examples For Speeches For Student

Have you ever watched a great film trailer and thought, “I have to see that movie!”? A good trailer gives you the basic premise of the movie, shows you the highlights, and encourages you to want to see more.

A good thesis statement will accomplish the same thing. It gives readers an idea of the most important points of an essay, shows the highlights, and makes them want to read more.

A well-constructed thesis serves as a lighthouse for your readers, offering them a guiding light in the stormy sea of claims and evidence that make up your argumentative essay.

It will also help keep you, the writer, from getting lost in a convoluted and directionless argument.

Most importantly, a good thesis statement makes a statement. After all, it’s called a thesis statement for a reason!

“This is an interesting statement!” you want your reader to think, “Let’s see if this author can convince me.”

This blog post will dissect the components of a good thesis statement and will give you 10 thesis statement examples that you can use to inspire your next argumentative essay.

The Thesis Statement Dissected

Before I give you a blanket list of thesis statement examples, let’s run through what makes for a good thesis statement. I’ve distilled it down to four main components.

1. A good argumentative thesis is focused and not too broad.

It’s important to stay focused! Don’t try to argue an overly broad topic in your essay, or you’re going to feel confused and unsure about your direction and purpose.


Don’t write, “Eating fast food is bad and should be avoided.”

This statement is too general and would be nearly impossible for you to defend. It leaves a lot of big questions to answer. Is all fast food bad? Why is it bad? Who should avoid it? Why should anyone care?

Do write, “Americans should eliminate the regular consumption of fast food because the fast food diet leads to preventable and expensive health issues, such as diabetes, obesity, and heart disease.”

In this example, I’ve narrowed my argument to the health consequences related to a diet of fast food. I’ve also chosen to focus on Americans rather than everyone in the universe. (Because, as we all know, inhabitants of the faraway planet Doublepatty 5 require the starches and fats inherent in fast food to survive).

2. A good argumentative thesis is centered on a debatable topic.

Back in the ‘80s, teens loved to say “that’s debatable” about claims they didn’t agree with (such as “you should clean your room” and “you shouldn’t go to that movie”). This age-old, neon-colored, bangle-wearing, peg-legged wisdom holds true today—in your thesis statement.

Don’t write, “There are high numbers of homeless people living in Berkeley, California.”

No one can argue for or against this statement. It’s not debatable. It’s just a fact.

An argument over this non-debatable statement would go something like this:

“There are lots of homeless people in Berkeley.”

“Yes, there sure are a bunch of them out there.”

“Yup.”

As you can see, that’s not much of an argument.

Do write, “Homeless people in Berkeley should be given access to services, such as regular food donations, public restrooms, and camping facilities, because it would improve life for all inhabitants of the city.”

Now that’sdebatable.

Opponents could easily argue that homeless people in Berkeley already receive adequate services (“just look at all those luxurious sidewalks!”), or perhaps that they shouldn’t be entitled to services at all (“get a job, ya lazy loafers!”).

3. A good argumentative thesis picks a side.

I went into a lot of detail about the importance of picking sides in my post The Secrets of a Strong Argumentative Essay. Picking a side is pretty much the whole entire point of an argumentative essay.

Just as you can’t root for both the Yankees and the Mets, you can’t argue both sides of a topic in your thesis statement.

Don’t write, “Secondhand smoke is bad and can cause heart disease and cancer; therefore, smoking should be outlawed in public places, but outlawing smoking is unfair to smokers so maybe non-smokers can just hold their breath or wear masks around smokers instead.”

A wishy-washy statement like this will make your reader scratch his head in puzzlement. Are you for smoking laws or against them? Yankees or Mets? Mets or Yankees?

Pick a side, and stick with it!

Then stick up for it.

Do write, “Secondhand smoke is just as harmful as smoking and leads to a higher prevalence of cancer and heart disease. What’s worse, people who inhale secondhand smoke are doing so without consent. For this reason, smoking in any public place should be banned.”

4. A good thesis makes claims that will be supported later in the paper.

As I explained in my blog post How to Create a Powerful Argumentative Essay Outline, Your claims make up a critical part of building the roadmap to your argument.

It’s important to first include a summary of your claims in your thesis statement. During the course of your essay, you will back each of your claims with well-researched evidence.

Don’t write, “Humans should relocate to Mars.”

This statement doesn’t include any supporting claims. Why should humans move to Mars? What are the benefits of moving to a planet without oxygen or trees?

Do write, “It is too late to save earth; therefore, humans should immediately set a date for their relocation to Mars where, with proper planning, they can avoid issues of famine, war, and global warming.”

This statement includes some thought-provoking claims. The reader will wonder how the author plans to defend them. (“Famine, war, and global warming can be easily avoided on Mars? Go on…”)

Now that you understand the four main components of a good thesis statement, let me give you more thesis statement examples.

10 Thesis Statement Examples

Finally, I’ve come up with 10 debatable, supportable, and focused thesis statements for you to learn from. Feel free to copy these and customize them for use in your own argumentative essays.

There are a couple of things to be aware of about the following examples:

  1. I have not done the research needed to support these claims. So some of the claims may not be useable once you dig into them.
  2. Be careful not to use these thesis statements word-for-word; I wouldn’t want you to get in trouble if your teacher did a copy/find Google maneuver on you!

#1. Why Vaccinations Should Be Mandatory

Inspired by this sample essay on vaccinations.

Today, nearly 40% of American parents refuse to vaccinate their children due to a variety of unfounded fears. Vaccinations against diseases such as polio, rubella, and mumps, should be mandatory, without exception, for all children of the U.S. who wish to attend school. These vaccinations are critical to the control and eradication of deadly infectious diseases.

#2. Government Surveillance Is Harmful

Inspired by this sample essay on government surveillance.

Government surveillance programs do more harm than good because they invade civil liberties, lead innocent people to suffer unfair punishments, and ultimately fail to protect the citizens that they are designed to safeguard. For these reasons, programs such as PRISM operated by the NSA should be discontinued.

#3 Financial Compensation for Organ Donors

Inspired by this sample essay on organ donation.

People who sign up for organ donation freely give their hearts and other organs, but this free system limits the number of available donors and makes it difficult for recipients to access lifesaving transplants. Thus, organ donors should be financially compensated to produce more available organs and, at the same time, to decrease profitable, illegal organ harvesting activities in the black market.

#4. Our School Is Too Dependent on Technology

Inspired by this sample essay on technology dependence.

Our school’s dependence on technology has caused students to lose the ability to think independently. This dependence has caused a greater prevalence of mood disorders, memory loss, and loneliness. Educators should combat these issues by requiring students to participate in regular technology detoxes.

#5 School Officials’ Should Fight Cyberbullying

Inspired by this sample essay on cyberbullying.

Bullying has extended far beyond school and into cyberspace. Even though these acts of aggression take place outside of school boundaries, school officials should have the authority to discipline students who engage in cyberbullying without fear of reprisal. Doing so will help improve the online behavior of students and decrease incidences of cyberbully-related suicide attempts.

#6 The U.S. Media Should Update the Depiction of Traditional Families

Inspired by this sample essay on families.

The U.S. media depicts the traditional family as being comprised of a mother, father, and children; however, this notion of the traditional family is outdated and can be harmful to children who look to this as the gold standard. The U.S. media should, therefore, expand and redefine the definition of the traditional American family to include divorced and remarried parents, extended families living together, and families with same-gender parents. This will increase the overall sense of happiness and well-being among children whose families don’t necessarily fit the mold.

#7 Student Loans Should Be Forgiven

Inspired by this sample essay on student loans.

Crippling student debt is stifling the growth of the U.S. economy because it inhibits graduates from being able to spend money on consumer goods and home purchases. To alleviate this, lenders should be required to forgive student loans in cases where students are unable to repay their debts. Doing so would benefit the growth of the economy by increasing tax revenues, unfreezing credit markets, and creating jobs.

#8 Marijuana Should Be Legalized

Inspired by this sample essay on legalizing marijuana.

Marijuana has numerous medical applications, such as treating symptoms of epilepsy, cancer, and glaucoma. Legalizing the use of marijuana in the U.S. will greatly benefit the medical sector by giving physicians access to this lifesaving drug.

#9 Foreign Aid to Africa Does Not Work

Inspired by this sample essay on foreign aid to Africa.

Sending foreign aid to African countries is doing more harm than good, and it should be discontinued; the practice has caused African countries to become vulnerable to inflation, currency fluctuations, corruption, and civil unrest.

#10 China’s One-Child Policy Should Be Reversed

Inspired by this sample essay on China’s one-child policy.

China’s one-child policy was intended to help control population growth. Instead, it has led to unintended and negative consequences, such as a diminishing labor force, an aging population, the neglect of basic human rights, and an unbalanced gender population. To improve China’s situation, the policy should be reversed.

Writing a Thesis Sentence: An Introduction

Few sentences in your paper will vex you as much as the thesis sentence. And with good reason: the thesis sentence is typically that one sentence in the paper with the potential to assert, control, and structure the entire argument. Without a strong, thoughtful thesis or claim, a paper might seem unfocused.

Complicating the matter further is that different disciplines have different notions of what constitutes a good thesis sentence. Sometimes you'll encounter differences not only from discipline to discipline, but also from course to course.  One of your professors might frown on a thesis sentence that announces your process:  "This paper will argue X by asserting A, B, and C." Another professor might prefer this approach. 

So what makes a good thesis sentence?

Despite the differences from discipline to discipline and from course to course, a good thesis will generally have the following characteristics:

A good thesis sentence will make a claim.

A good thesis rarely turns an intellectual problem into a black & white, "either/or" proposition that the writer will then defend. Rather, a good thesis offers a nuanced and interesting perspective that the writer can develop via careful analysis. This perspective must be more than an observation.  For example, "America is violent" is an observation. "Americans are violent because they are fearful" (the position that Michael Moore takes in Bowling for Columbine) is an argument. Why? Because it posits a perspective. It makes a claim.

Put another way, a good thesis sentence will inspire (rather than quiet) other points of view. One might argue that America is violent because of its violent entertainment industry. Or because of the proliferation of guns. Or because of the disintegration of the family. In short, if your thesis is positing something that no one can (or would wish to) argue with, then it's not a good thesis.

A good thesis sentence will define the scope of your argument.

Your thesis sentence determines what you will discuss in your paper. It also determines what you won't discuss. Every paragraph in your paper exists in order to support your thesis and its claim. Accordingly, if one of your paragraphs seems irrelevant, you have two choices: get rid of the paragraph, or rewrite your thesis so that it is complex enough to embrace the whole of your argument. 

A good thesis will shape your argument.

A good thesis not only signals to the reader what claim you're making, but also suggests how your argument will be presented. In other words, your thesis sentence should suggest the structure or shape of your argument to your reader.

Say, for example, that you are going to argue that "American fearfulness expresses itself in two curious ways: A and B." In this case, the reader understands that you are going to have two important points to cover, and that these points will appear in a certain order. If you suggest a particular ordering principle in your thesis and then abandon it, the reader could become confused.

Developing A Thesis:  Sample Methods

Professors employ a variety of methods to teach students how to compose good thesis sentences.  Your professor has likely demonstrated several methods to you.  Here we offer sample methods employed by three instructors from the Institute for Writing and Rhetoric:  John Donaghy, Sara Biggs Chaney, and Karen Gocsik.  Please note that these methods do not represent a program-wide sense of the thesis and how it should be taught or practiced.  In fact, no such program-wide method exists.  Instructors in the Institute for Writing and Rhetoric believe that there are many approaches which can help students compose a good thesis.  We offer you these examples with the hope that you will think about their underlying principles and consider how these principles might transfer to the work that you're doing in your classrooms. 

JOHN DONAGHY: FINDING PATTERNS, SOLVING PROBLEMS

Professor John Donaghy's method is founded on the understanding that a good thesis comes from good analysis. In his view, analysis is a complicated process that requires readers to break down a text (event, object, or phenomenon) into parts, discovering patterns among the parts, and coming up with a theory for why these patterns exist. Professor Donaghy believes that students are initially afraid of analysis. He's puzzled by this fear. In fact, Professor Donaghy argues, we are analyzing all the time: life presents us with data that we are continually sorting by finding patterns, creating categories, and making meaning. Analysis is necessary for something as simple as crossing the street. Students can be encouraged to see that they already possess analytical skills that can be transferred to writing papers.

To illustrate how analysis brings us to the development of a thesis, Professor Donaghy suggests three steps regarding a simple reading of the following Gary Snyder poem, "Pine tree tops:"

In the blue night
frost haze, the sky glows
with the moon
pine tree tops
bend snow-blue, fade
into sky, frost, starlight.
The creak of boots. Rabbit tracks, deer tracks,
what do we know.

First, when analyzing, students need to be conscious of examining parts of a text, looking for patterns (or repeating elements). In a short poem, students can make a number of simple observations, including:

  • Number of words (34)
  • Number of syllables in words (mostly single syllable)
  • Parts of speech: mostly nouns; adjectives are scarce; surprisingly few verbs

Second, students need to try to determine how these parts and patterns are speaking to each other. Do these parts and patterns illustrate a similarity? Draw a contrast? Create an emphasis? Together form a new observation or idea? In terms of the poem:

  • Nouns: so many nouns emphasizes the "thing-ness" of the poem
  • Adjectives: very few; one (blue) is attached to a noun
  • Verbs: the verbs (glows, bend, fade) are gentle, yielding verbs

Finally, students can put forward a proposition. For instance: Snyder builds his poem on nouns to give power to the "things" in his scene. Or Snyder chooses verbs that seem to yield to the nouns in order to tell us how to behave in the presence of nature. This proposition, with some tweaking, can become a working thesis.

SARA BIGGS CHANEY: EVOLVING THE THESIS BY UNPACKING THE ASSUMPTIONS & MAKING COUNTER-CLAIMS

Professor Sara Chaney uses various methods to help her students arrive at a thesis. One that has proven successful is requiring students to examine their assumptions. Professor Chaney begins this instruction by introducing the student to the enthymeme. Like the syllogism (All men are mortal; Socrates is a man; therefore, Socrates is mortal), the enthymeme has three parts: the major premise, the minor premise, and the conclusion. The difference is that in the case of the syllogism, the major premise is based on fact (All men are mortal), while in the enthymeme it's based on a commonly held belief (cheating is unethical, smoking around children is a danger to their health, etc.). As Professor Chaney notes, in many cases the enthymeme is presented with the major premise left unstated: She smokes around her daughter; she endangers her daughter's health. Professor Chaney illustrates the importance in finding the "missing" major premise, arguing that unpacking an argument's unstated assumptions can help students to better analyze the texts they're writing about, and to create better texts of their own.

The key question to ask is: What must be true about the world in order for this statement to be true? Students are asked to put forth all hidden assumptions, large and small. This forces the students to dig beneath the surface of the text, to explore the structure and the nuance of the argument. In the process, ideas for a thesis will present themselves.

Once the students have drafted a thesis, Professor Chaney has a strategy (borrowed from David Rossenwasser and Jill Stephen's Writing Analytically) for evolving the thesis by putting forward counter-claims. Students sometimes make the mistake of forcing evidence to fit an overly rigid claim, or of presenting their claim in the form of a list, with few connections between the points. To evolve the thesis, Professor Chaney asks students to begin with their basic claim and then to methodically increase the complexity of that claim through the introduction of complicating evidence. This new evidence forces students to redefine their initial claims and to determine how the counter-claim might or might not be accommodated by their thesis.

For instance, a student may have written the following thesis: "Reported cases of autism in children have increased by almost 200% in the last twenty years because autism has been redefined to include less severe forms of the disorder." Professor Chaney presents students with this complicating evidence: "Some research also suggests that autism may be linked to mercury exposure in childhood vaccines." Students may weigh the evidence to see which has more merit; they might expand their thesis to point to two reasons for rising autism; they might acknowledge the truth in both statements but want to subordinate one argument to the other; they might point out a causal relationship between the two sentences (i.e., has the frequent levels of mercury exposures led to a new definition of autism in the DSM-IV, which in turn has increased the numbers of reported cases of autism?). Using any of these methods, students will have improved their thesis sentences.

KAREN GOCSIK: FINDING THE UMBRELLA IDEA

Professor Karen Gocsik advises that developing a good thesis is often the result of finding the "umbrella idea." Finding this idea requires that students move back and forth between a text's particularities and its big ideas in order to find a suitable "fit" between the two that the students can write about. This fit is then summed up in the "umbrella idea," or the big idea that all of their observations can stand under.

For instance, in an exploration of the Gospels as rhetoric, a student makes the specific observation that, in three of the four gospels, Jesus is reported as saying dramatically different things during his crucifixion.  This observation by itself won't produce a paper - it's simply a statement of fact, with which no one will disagree.  Nevertheless, this observation provokes a broader question:  do these differences constitute a contradiction in the text?  And if so, how do we understand this contradiction?  What are the conditions of religious truth?  Is there room for a contradiction as important as this?

Of course, these questions are too big to be addressed in an academic paper.  And so the student returns to the text, still with these too-big questions haunting him.  Reviewing the specific contradictions of the text, he crafts another set of questions:  How should we understand the differences we see across the four gospels?  What might have inspired these writers to craft this important crucifixion scene differently - particularly when, as is true of the authors of Matthew and Luke, they were using the same sources?  The student posits that these differences arise from a difference in audience, historical moment, and rhetorical purpose.  He turns to scholarship and finds his interpretation confirmed.

But the bigger questions persist.  If the gospels are constructed to serve the earthly purposes of converting or supporting the beliefs of specific audiences, how can they also be considered as true?  After doing a great deal of sketching, the student posits that perhaps the differences and contradictions are precisely what communicates the texts' truth to its audience of believers.  After all, if the truth of a supreme being is beyond human grasp, then perhaps it requires a many-voiced or polyglossic narrative.  With this idea in mind, the student produces a paper that not only details the variances across the texts, but offers a claim about why an audience of believers are not deterred by the differences. It is this claim that serves as the umbrella idea, synthesizing the student writer's various observations and ideas.

To sum up, successful employment of the umbrella method depends on four steps:

  1. Students must move fluidly back and forth between the text and their abstractions/generalizations, ready to adjust their ideas to the new evidence and new abstractions that they encounter.
  2. Students must sketch their ideas. Drawing their ideas helps students pull their thinking out of linear, two-dimensional modes, enabling them to see multiple possibilities for their essays.
  3. Students must seek an umbrella idea, under which their ideas can stand. To get to this umbrella idea, they need not only to analyze but to synthesize: they need to bring disparate ideas together, to see if they fit.
  4. They further need to create this synthesis by playing with language, creating an umbrella sentence that can embrace their ideas. This requires that students write and revise their thesis sentence several times as they write their paper. It also requires that students have a basic understanding of the principles of style, so that they can understand how to place their ideas in appropriate clauses, create the proper emphasis, and so on.

Alternatives to the Thesis Sentence

Sometimes, the purpose of a piece of writing is not to make a claim but to raise questions. Other times, a writer wants to leave a matter unresolved, inspiring the reader to create his or her own position. In these cases, the thesis sentence might take other forms: the thesis question or the implied thesis.

The Thesis Question

As we've said, not every piece of writing sets out to make a claim. If your purpose as a writer is to explore, for instance, the reasons for the 9/11 attacks (a topic for which you are not prepared to make a claim), your thesis might read: "What forces conspired to bring these men to crash four jetliners into American soil?"

You'll note that this question, while provocative, does not offer a sense of the argument's structure. It permits the writer to pursue all ideas, without committing to any. While this freedom might seem appealing, in fact you will find that the lack of a declarative thesis statement requires more work: you need to tighten your internal structure and your transitions from paragraph to paragraph so that the essay is clear and the reader can easily follow your line of inquiry.

The Implied Thesis

One of the most fascinating things about a thesis sentence is that it is the most important sentence in a paper - even when it's not there.

Some of our best writers never explicitly declare their theses. In some essays, you'll find it difficult to point to a single sentence that declares the argument. Still, the essay is coherent and makes a point. In these cases, the writers have used an implied thesis.

Writers use an implied thesis when they want to maintain a light hand. However, just because the writer doesn't delcare the thesis doesn't mean that she was working without one. Good writers will have their thesis clearly stated - either in their own minds, or in their notes for the paper. They may elect not to put the thesis in the paper, but every paragraph, every sentence that they write is controlled by the thesis all the same.

If you decide to write a paper with an implied thesis, be sure that you have a strong grasp of your argument and its structure. Also be sure that you supply adequate transitions, so that the reader can follow your argument with ease.

Will This Thesis Sentence Make the Grade? (A Check List)

In the end, you may have spent a good deal of time writing your thesis and still not know if it's a good one. Here are some questions to ask yourself.

  • Does my thesis sentence attempt to answer (or at least to explore) a challenging intellectual question?
  • Is the point I'm making one that would generate discussion and argument, or is it one that would leave people asking, "So what?"
  • Is my thesis too vague? Too general? Should I focus on some more specific aspect of my topic?
  • Does my thesis deal directly with the topic at hand, or is it a declaration of my personal feelings?
  • Does my thesis indicate the direction of my argument? Does it suggest a structure for my paper?
  • Does my introductory paragraph define terms important to my thesis? If I am writing a research paper, does my introduction "place" my thesis within the larger, ongoing scholarly discussion about my topic?
  • Is the language in my thesis vivid and clear? Have I structured my sentence so that the important information is in the main clause? Have I used subordinate clauses to house less important information? Have I used parallelism to show the relationship between parts of my thesis? In short, is this thesis the very best sentence that it can be?

What else do you need to know about thesis sentences?

A good thesis usually relies on a strong introduction, sharing the work.

As your writing becomes more sophisticated, you will find that a one-sentence thesis statement cannot bear the burden of your entire argument. Therefore, you will find yourself relying increasingly on your introduction to lay the groundwork. Use your introduction to explain some of your argument's points and/or to define its terms. Save the "punch" for your thesis. For more information about creating good introductions that can support your thesis sentences, see Introductions and Conclusions elsewhere in this website.

The structure of your thesis, along with its introduction, should in some way reflect the logic that brought you to your argument.

It's helpful when structuring your thesis sentence to consider for a moment how it was that you came to your argument in the first place. No matter what discipline you are working in, you came to your idea by way of certain observations. For example, perhaps you have noticed in a History of Education course that female college students around the turn of the century seem very often to write about the idea of service to the community. How did you come to that observation? What did you observe first? And, more importantly, how did you go about exploring the significance of this observation? Did you investigate other college documents to see if the value of service was explicitly stated there? Or was this value implied in course descriptions, extra curricular possibilities, and so forth? Reconstruct for yourself how you came to your observations, and use this to help you to create a coherent introduction and thesis.

A good working thesis is your best friend.

Those writers who understand the concept of "working thesis" are way ahead of the game. A "working thesis" is a thesis that works for you, helping you to see where your ideas are going. Many students keep their working thesis in front of them at all times to help them to control the direction of their argument. But what happens when you stumble onto an idea that your thesis isn't prepared for? Or, more important, what happens when you think everything is going well in your paper and suddenly you arrive at a block? Always return to your working thesis, and give it a critical once-over. You may find that the block in your writing process is related to some limitation in your thesis. Or you may find that hidden somewhere in that working thesis is the germ of an even better idea. Stay in conversation with your thesis throughout the writing process. You'll be surprised at what you can learn from it.
