Argumentative Essay

The thesis statement

Your thesis statement expresses the main position of your essay. It should be clear enough for the reader to understand exactly what you are arguing.

Weak: Social media has both advantages and disadvantages.

Stronger: Social media companies should be required to verify the age of users under 18.

The second version takes a position that can be defended with arguments.

Arguments need development

An argument is more than a statement. A strong argument normally contains:

• a clear claim
• an explanation
• evidence or an example
• a connection back to the thesis

Instead of writing:

School uniforms are good because they create equality.

develop the idea:

School uniforms can reduce visible differences between students from different economic backgrounds. When clothing is less connected to status and expensive brands, students may experience less pressure to compete through appearance.

Evidence and examples

Evidence makes an argument more convincing. Depending on the task, you might use:

• facts and statistics
• research
• expert opinions
• real-world examples
• relevant comparisons
• logical reasoning

Evidence should support the argument rather than replace your own explanation.

Counterarguments

A strong argumentative essay recognises that other perspectives exist.

You can introduce a counterargument:

Critics may argue that…

Then respond to it:

However,…

A counterargument should not simply be mentioned. Explain why your position remains stronger.

• Topic: Should the voting age be lowered to 16?
• Thesis: The voting age should be lowered to 16 because political decisions affect teenagers directly and earlier participation could strengthen democratic engagement.
• Argument: Young people are directly affected by decisions about education, climate policy and public transport.
• Development: Giving 16- and 17-year-olds the right to vote would allow them to influence political decisions that already shape their everyday lives and future.
• Counterargument: Critics may argue that sixteen-year-olds lack the experience required to make informed political decisions.
• Response: However, political knowledge differs greatly among adults as well, and age alone does not guarantee that a voter is well informed.

1. Decide exactly what position you want to defend.
2. Write your thesis in one clear sentence.
3. Choose two or three strong arguments.
4. Develop each argument with reasoning, evidence or examples.
5. Include a relevant counterargument and respond to it.
6. End by bringing the argument together rather than introducing a completely new point.

Weak: “Everyone knows that social media is bad for teenagers.”

Better: “Frequent social media use has been linked to several concerns about teenagers’ wellbeing.”

Why: Avoid sweeping claims such as everyone knows, always and obviously.

Weak: Three arguments are mentioned in three sentences.

Better: Each main argument is given its own paragraph and developed with explanation and evidence.

Why: Depth is usually more persuasive than a long list of undeveloped claims.

Weak: “Some people disagree with this.”

Better: Explain what the opposing argument actually is and respond to it.

Why: A vague counterargument does not show that you understand the opposing perspective.

Weak: Evidence is inserted without explanation.

Better: Explain what the evidence shows and why it supports your thesis.

Why: The reader should never have to work out the connection for you.

Which is the strongest thesis statement?

• A. Artificial intelligence is becoming increasingly common in schools.
• B. Is artificial intelligence good or bad for students?
• C. Schools should teach students how to use artificial intelligence responsibly rather than banning it completely.
• D. There are many opinions about artificial intelligence.

Answer: C. It expresses a clear position that can be defended with arguments. The other alternatives introduce the topic without taking a position.

• Your thesis states the position you are defending.
• Each argument needs explanation and support.
• Evidence should be connected to your reasoning.
• A counterargument can strengthen your credibility when you respond to it.
• The whole essay should contribute to the same central argument.
