What is an argument?
In everyday life, an argument might mean a disagreement. In reading and writing, an argument is a reasoned attempt to persuade an audience to accept a claim. Arguments appear in editorials, speeches, advertisements, reviews, essays and debates.
Learning to analyze arguments helps you think critically about what you read, hear and watch. You become harder to fool.
The parts of an argument
| Part | Function | Example |
|---|---|---|
| Claim | the main position | Schools should start later in the morning. |
| Reasons | why the claim is true | Teens need more sleep to learn effectively. |
| Evidence | support for each reason | A study of 9,000 students found later start times improved grades and attendance. |
| Counterclaim | the opposing view | Some argue later starts disrupt after-school activities and parents’ schedules. |
| Rebuttal | response to the counterclaim | However, schools that shifted schedules found ways to adjust activities, and the academic benefits outweighed the inconvenience. |
| Conclusion | restates claim, calls to action | School boards should adopt later start times to support student health and success. |
Types of claims
- Claim of fact: argues something is true. Social media use is linked to increased anxiety among teens.
- Claim of value: argues something is good or bad. Volunteering is the most rewarding way to spend free time.
- Claim of policy: argues something should be done. Our city should ban single-use plastic bags.
Types of evidence
| Type | Example | Strength | Caution |
|---|---|---|---|
| Statistics | 70 percent of teens… | precise, measurable | check source and context |
| Expert testimony | According to a pediatrician… | authority | expert must be relevant |
| Research findings | A study published in… | rigorous | consider sample and date |
| Examples | In Seattle, schools that… | concrete | may not represent all cases |
| Anecdotes | My cousin… | emotional, relatable | not proof alone |
| Facts | The law took effect in 2019. | verifiable | must be accurate |
Evaluating an argument
To evaluate, ask three big questions.
1. Is the evidence relevant?
Does it directly support the reason? A statistic about adult sleep may not support a claim about teens.
2. Is the evidence sufficient?
Is there enough? One anecdote is rarely sufficient to prove a general claim.
3. Is the reasoning sound?
Sound reasoning clearly connects evidence to the claim without logical gaps.
Credibility
Is the evidence from a credible source? Consider the author’s expertise, the publication’s reputation, the date, and possible bias or conflicts of interest. A study funded by a soda company about sugar’s health effects deserves extra scrutiny.
Counterclaims and rebuttals
Strong arguments address opposing views. Including a counterclaim and rebuttal:
- shows the author has considered other perspectives,
- builds credibility and fairness,
- strengthens the argument by answering objections before readers raise them.
Rebuttal phrases: However, … / Although some argue …, the evidence shows … / While it is true that …, …
Persuasive techniques
Authors also use rhetorical appeals:
- Logos (logic): facts, statistics, reasoning.
- Ethos (credibility): expertise, trustworthiness, fairness.
- Pathos (emotion): stories, vivid language and images that stir feelings.
Effective arguments balance all three. Over-reliance on emotion without evidence is a warning sign.
Recognizing faulty reasoning
Watch for common logical fallacies:
- Overgeneralization: All teenagers are addicted to their phones.
- Bandwagon: Everyone is buying this, so you should too.
- Attacking the person: Don’t listen to her; she’s not even from here.
- Either/or: Either we ban phones in school or students will never learn.
- Slippery slope: If we let students choose their seats, soon there will be no classroom rules at all. (assumes one step leads to extreme results)
- False cause: I wore my lucky socks and we won, so the socks caused the win.
A process for analyzing an argument
- Identify the claim.
- List the reasons.
- Examine the evidence for each reason: type, relevance, sufficiency, credibility.
- Look for counterclaims and rebuttals.
- Note persuasive appeals and any fallacies.
- Evaluate overall: Is the argument convincing? Why or why not?
Worked example
Excerpt: Our school should replace vending machine soda with water and juice. Sugary drinks contribute to obesity and tooth decay; the World Health Organization recommends limiting added sugar. In addition, when a nearby district removed soda in 2021, student visits to the nurse for headaches dropped. Some students say they should be free to choose their drinks. However, the school’s role is to support healthy habits, and students can still bring any drink from home.
- Claim: replace soda with water and juice (policy).
- Reasons: health risks; positive results elsewhere.
- Evidence: WHO recommendation (expert), district example.
- Counterclaim: freedom of choice. Rebuttal: school’s role; students can still bring drinks.
- Evaluation: reasonably strong; the district example would be stronger with data on how many visits and whether other factors changed.
Try it yourself
- Identify the type of claim: Every student should learn a second language.
- Is this evidence relevant to a claim that homework should be reduced? Most students prefer weekends without homework.
- Name the fallacy: If we allow phones at lunch, soon students will be texting through every class.
- Write a rebuttal for the counterclaim Later school start times would make buses more expensive.
Answers: 1. Policy. 2. Weakly; preference does not show that reducing homework improves learning or wellbeing. 3. Slippery slope. 4. Example: Although bus schedules would need adjusting, districts that changed found costs manageable, and improved attendance offset some expenses.
Study tip
When you see an advertisement or opinion post, practise a 30-second analysis: claim, best piece of evidence, weakest piece of evidence, and one missing perspective.
Quick recap
- An argument has a claim, reasons, evidence, counterclaims, rebuttals and a conclusion.
- Evaluate evidence for relevance, sufficiency and credibility.
- Sound reasoning connects evidence logically to the claim.
- Recognize appeals (logos, ethos, pathos) and fallacies.
- Strong arguments address opposing views fairly.
