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:
Pollution is bad for the environment.
This thesis statement is not debatable. First, the word pollution means that something is bad or negative in some way. Further, 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 good.
Example of a debatable thesis statement:
At least 25 percent of the federal budget should be spent on limiting pollution.
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:
America's anti-pollution efforts should focus on privately owned cars.
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:
Drug use is detrimental to society.
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:
Illegal drug use is detrimental because it encourages gang violence.
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:
At least 25 percent of the federal budget should be spent on helping upgrade business to clean technologies, researching renewable energy sources, and planting more trees in order to control or eliminate pollution.
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:
America's anti-pollution efforts should focus on privately owned cars because it would allow most citizens to contribute to national efforts and care about the outcome.
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, 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:
What some people refer to as global warming is actually nothing more than normal, long-term cycles of climate change.
Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:
The popularity of SUVs in America has caused pollution to increase.
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:
Global warming is the most pressing challenge facing the world today.
Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:
Instead of drilling for oil in Alaska we should be focusing on ways to reduce oil consumption, such as researching renewable energy sources.
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.
What does a good thesis statement look like?
There is one big tip on writing a good essay almost every article on the web gives you. It’s to come up with a clear and specific thesis statement.
But how one does it? You need to understand what is the main idea of your paper and how to communicate it in a comprehensive and concise way. Here are some of the thesis statement examples to help you make this task less problematic.
Thesis statement formula
As you can see, there is no universal thesis statement formula as every type of a writing assignment requires a different approach. In some cases, you will have to include counterarguments, and in others presenting solely your point of view will suffice. Here are a couple of examples:
While there is a common belief that ……., a closer examination proves that …….
Despite the ……., the recent facts show that ……
The reason for is …… and as a result …….
- Endorsement of child labor by international companies should not be supported.
Consumers should not buy items from the countries that endorse child labor because this kind of financial approval encourages big corporations to increase the production, the exhaustion of a child’s body can lead to severe health problems, and the hard work deprives children of their childhood.
- The morality of atheists and theists.
Even though atheists do not have an instruction of good behavior provided by the superior beings, they are not less moral than theists. They have their own moral compass and laws established by society to differentiate good deeds from the bad ones.
- Testing drugs on animals is the sacrifice we have to make.
The greatest value we have is a human life. If testing a new drug on a cute little rabbit could result in saving your mother or father from a terminal illness, then this is the sacrifice we need to make. Animal testing can lead to our healthier future, less incurable diseases, and more saved lives.
- Getting a university diploma is necessary.
Even though there are some examples of successful people without a college degree, everybody should go through this stage of self-development. The years in college give you knowledge, improve your soft skills, and connect you with other bright people who can help you get to the top in the future.
- Personal information on the web should have a legislative basis.
Even though we can’t imagine our life without social media, we have to be careful about the information we provide as it can be used for research reasons. There should be specific laws about the availability of big data and who can use it because it will be easy to manipulate people’s minds, gather the personal information without permission and use it for someone’s benefits.
- Landing on the Moon is a fake.
Despite the presence of a documentary video of landing on the Moon, it should be recognized as the biggest fraud. The details of the video and the fact that we still have not made a come back there after more than 40 years indicate that it could not be filmed on the Moon surface.
- Parents monitoring their children internet use is the right thing.
While there is a lot of useful and educational information on the internet, parents should regulate the internet use of their children. Children get distracted, spend more time on harmful web sites, and avoid social interaction.
- Money as a motivation for good grades is an option.
The approach of encouraging the children to get good grades by paying them can be a model of the real world situation. If you work hard and get good results, you will get paid accordingly. This way of encouragement is acceptable and can be used by parents.
- The line between exaggeration and lies in advertising.
There are not enough regulatory norms to make the modern advertisement less deceiving. The line between exaggeration and lies is not clear and the products advertised turn often don’t meet the customers’ expectations. If we introduce more rigid rules to advertising, there will be less disappointed customers.
- Space missions should not be a priority.
We spend billions of dollars on developing the strategies of Mars colonization while there are millions of people suffering from famine here, on our planet. It would be more beneficial to spend more on saving people in Africa from starvation and water shortages than sending someone to a distant planet.
- Unfair salary rates of doctors.
In the world where human life is the biggest value, doctors should get the highest salary rates, not actors and singers. They save lives, deprive us of physical pain, and have to spend years of studying and practicing to be able to do that.
- Euthanasia should be legalized.
Euthanasia should be recognized as one of the possible ways of ending a person’s life. The right of life is given to every person and we are free to take decisions we consider to be right.
- Homeschooling is effective.
Homeschooling is an effective way of educating children as it gives an opportunity to focus on personal strength and weaknesses, make emphasis on the particular subjects a child has an interest in, and adapt the studying approach to the most convenient for a child.
- Diets are just waste of time.
Multiple cases show that all the diets have a short-term effect on the body. Diets are ineffective because people start gaining weight once they stop and the organism goes through an unnecessary stress.
- The production of cigarettes should decrease by 90%.
The production of cigarettes should decrease by 90% so that with time, the harmful habit could disappear. A significant decrease in the production of tobacco products will lead to the minimization of demand on it as the price will get higher, the supply will decrease and people will not be able to buy it.
- Reverse discrimination at the workplace is a problem.
The fear of being punished for the discrimination of ethnical minorities at the workplace leads to the discrimination of the rest of the population. There should be a law that balances out this inequality.
- Redistribution of money spent on the space programs is needed.
The government should not spend money on the search for new exoplanets as it has no practical value for people on Earth. Instead, they should focus on asteroid mining projects to be able to get the vital resources after they are all used on our planet and survive.
- Plastic surgeries should not be allowed to everyone.
Even though plastic surgeries are aesthetically justified, they do not solve the psychological problems of desire to change one’s appearance. They should be allowed only in severe cases because they give people the fake satisfaction, can cause an addiction, and support the objectification of one’s image.
- Video games advocating violence should be banned.
Video games featuring violent episodes should be banned as they lead to violence at schools, damage the mentality of minds, and create the perverted image of reality.
- Abortions should be legal.
The legalization of abortions should be legalized as women should have the freedom to make decisions regarding their bodies and there are cases when there could be no other solution to the problem.
- Endorsement of child labor by international companies should not be supported.
- Studying abroad.
Although the idea of studying abroad might sound costly, the experience one will get from the interaction with another culture and different approach to teaching is worth it.
- Marriage at a young age.
There is nothing good about getting married at a young age except for it being romantic. People’s personalities change dramatically between 20 and 30 years old and young marriages are almost never a good idea.
- Getting a degree.
Higher education is no longer a requirement for getting the dream job. Online short-term courses can give you the necessary theoretical information.
- Women choosing not to have children.
There is nothing scandalous about a woman who chooses not to have children and our society has to understand that. It is her time and body that are at stake but not someone’s beliefs.
- Modern art.
Modern art becomes more and more meaningless as almost every creative project has a goal of provoking negative emotions.

There is an urgent need of educating people about AIDS as there are many countries even in Europe where the information about this disease is inaccurate and unspecific.
- Protecting animals.
Every civilized country should ban circuses that use animals for their shows. This kind of entertainment is not worth the sufferings those animals go through.
Becoming a vegetarian is a new stage of the human development as you stop being an animal and make a conscious choice of not eating meat for the sake of other animals just like you.
Choosing death instead of life is a selfish deed by which you take the joy of your life not from yourself but from the people who love you.
- Studying abroad.
- Plants in the developing countries.
International companies having their factories in the developing countries provide thousands of people with work and stable income. The question of ethics should not stand in the way of helping those people to survive.
- 6 hour work day
The U.S. should introduce a 6 hour work day for office workers to reduce sick-leave and increase the motivation.

- Personal information.
The federal government should not have access to the personal information we state online and should not be able to use it.
- Food at school cafeterias
The food at school cafeterias is one of the main reason of children’s obesity in the U.S. the government should introduce legal regulations regarding this issue.
