A contest of reasons
In a debate, two sides take turns giving reasons about one question. One side argues for it, the other against. A judge (or an audience) listens to both and decides which side made the better case in that round.
That last part matters. A debate doesn’t settle whether school uniforms are good. It settles which team argued better about school uniforms on Tuesday afternoon. That is why debaters can argue a side they don’t personally hold, and why the same topic can be won by either side.
How it differs from an argument
An everyday argument and a debate both involve disagreeing, but a debate adds rules that make it fair and useful.
| Everyday argument | Debate | |
|---|---|---|
| Turns | Whoever talks loudest or longest | Equal, timed speeches in a set order |
| Question | Drifts from topic to topic | One resolution, written down |
| Winner | Usually no one; sometimes whoever gives up last | A judge decides, and explains why |
| Evidence | “Everybody knows…” | Sources you can name and the other side can check |
| Goal | To be right | To make the best case and test the other one |
The parts of a debate
- The resolution: the statement being debated, such as “Resolved: Schools should start no earlier than 8:30 a.m.” (See Reading a Resolution.)
- Two sides: the affirmative (or pro, or proposition, or government) supports the resolution; the negative (or con, or opposition) opposes it.
- Speeches: constructives build a case; rebuttals answer the other side and sum up.
- Questioning: most formats give each side time to question the other: cross-examination, crossfire, or points of information.
- Prep time: a few minutes each side can use between speeches to plan.
- A judge: who fills out a ballot with the winner and the reason for the decision.
Why people debate
Debaters learn to research a question, organize their thoughts, speak in front of others, listen closely, and think on their feet. Just as important, they learn to understand views they don’t share. You can’t answer an argument you don’t understand, so debate trains you to listen for the best version of the other side.
Aristotle, writing more than two thousand years ago, put it this way: we should be able to argue on opposite sides of a question, not so we can argue for what is wrong, but so we “see clearly what the facts are” and can answer someone who argues unfairly.

A tiny debate
Affirmative Pizza night gives us one dinner a week nobody has to cook, so whoever usually cooks gets a break. It’s also something to look forward to at the end of the week.
Negative A break for the cook is a good goal, but takeout pizza every week costs a lot over a year, and it’s the same meal every time. A rotating Friday where a different person cooks something simple gives the break without the cost.
Affirmative They agree the cook needs a break. Their plan still makes someone cook. Ours is the only one where nobody does. We can keep the cost down by making pizza at home from frozen dough.
Negative If we’re making it at home, someone is cooking after all. So the real question is which costs less and gives more variety, and that’s the rotating Friday.
Notice what both sides did: each answered the other side’s actual point, agreed where it was fair to agree, and ended by telling the judge what the round comes down to.
Where to debate
Most American high schools with a team compete in leagues run by the National Speech & Debate Association or a state association. Homeschoolers have leagues of their own (NCFCA and Stoa), and many colleges have teams. You don’t need a league to start: a classroom, a co-op or a family can hold debates with a timer and a topic. See Formats and Resources.
Practice
- Pick a topic from the topics list and write one sentence for each side.
- Hold the two-minute dinner-table debate above with a family member, then switch sides and do it again.
- Watch a short recorded debate and write down the resolution, the two sides and who you think won, with one reason.
