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.
To begin with, you need to define what kind of paper are you writing and which thesis statement do you need. The main four types include expository, analytical, argumentative and persuasive.
Expository essay requires only writer’s explanation of an idea and issue, possibly with his/her own response, thoughts, perception or attitude to it. Nevertheless, a well-defined thesis statement as well as evidence to back up your saying is required. If you are thinking who will write my thesis, than at least these points should be considered.
In analytical paper you are asked to examine and evaluate particular issue, idea or work, interpret and present the results to the audience. The idea or issue you want to examine should be reflected in the thesis statement.
In persuasive essay you are trying to win your readers over and convince them to adopt your point of view. At this point having a strong argument is the most important.
The point of an argumentative paper is to prove that your opinion or hypothesis is more precise or accurate that the others. It is different from the persuasive essay since here you oppose your opinion to the others and not just convince your reader to adopt yours.
Depending on the type of paper you are writing the thesis statement will be different as well. However, in any case the thesis statement should be arguable. For example: “Global warming is bad for the environment”. This is rather a fact than an opinion, someone would reasonably argue with. Another example is “Global warming is largely attributed to human activities and connected with massive industrialization”. Basically, someone could argue about the causes of rising temperature.
Make sure your thesis statement isn’t too general like here: “Deforestation has not caused as much global warming as gas emissions from fossil fuels”. This statement is difficult to argue and it will require too much evidence to be proven. An example of more focused and narrowed thesis is the following:”Deforestation over he last 20 years has not caused as much global warming as gas emissions from fossil fuels in Eastern Europe”.
Your thesis might also change depending on the claim you want to make. Generally there are four main types:
- Claim of fact. Example: “Among many people, global warming is believed to be a stage in a normal cycle of climate”. You may try to prove this opinion to be a fact.
- Claim of cause and effect. Example: “Frequency and intensity of tropical storms is increasing dramatically because of the global warming”. You may argue if the rising frequency of tropical storms can be put down to the global warming effects.
- Claim of value. Example: “Global warming is perceived as the reason for new diseases emergence”.
- Claim of solution. Example: “A rational financial analysis has shown that it will be cheaper to adapt to a warmer climate rather than try to prevent global warming”. You may offer some solution to a particular problem and back up it with appropriate evidence.
Your thesis statement will mostly depend on a particular issue you want to discuss as well as your point of view. Remember to represent in your paper both signs of agreement and disagreement, it will make your paper more objective.
