Why you should argue the side you disagree with

Most of us argue for what we already believe. It feels good, it is easy, and it teaches us very little. The fastest way to find out how well you understand your own view is to spend twenty minutes defending the opposite one.

This guide explains why that works, how to do it without faking it, and how to practice it with a real opponent online.

What you gain

• You find out what the other side actually says. Most people know a cartoon version of the view they reject. You cannot argue a cartoon for long, so you have to look up the real thing.
• You see where your own view is thin. Once you have built the best case against your position, you know which of your reasons survive it and which were habits.
• You get better at listening. When you have just argued a side, you answer the person in front of you instead of the person you imagined.
• You lose less when you are wrong. Changing your mind is easier if you have already stood in the other place.

What it is not

Arguing a side is a training exercise, not a confession. You are not lying, and you are not announcing that you have changed your mind. On theChatStage the sides are chosen by the debater, and you are welcome to argue a view that is not your own. The point is to find the strongest case, not to play a character.

How to do it well

1. Pick a topic where you have a mild view, not a deep one

Start where you lean one way but could be moved. Something like school uniforms or a four-day workweek works better than a question tied to your identity. Save the hard ones for later. The full topic list is grouped by category.

2. Write down the three best reasons for the side you will argue

Before you start, list the three strongest reasons a thoughtful person would give for the view you are about to defend. If you struggle to name three, read a little first. Look for the reasons people who hold the view would give, not the ones their critics attribute to them.

3. Lead with your best point, not your easiest

The temptation is to open with a weak argument you can win. Open with the one that does the most work. If it falls, you learn something; if it stands, you have a position.

4. State what your opponent said before you answer it

Restate their point in a sentence they would accept, then respond. It slows you down in a useful way, and it stops you arguing against something they never said.

5. Ask what evidence would change the mind of the side you hold

Every good position has a condition under which it would be dropped. Naming it in the debate makes you sharper and makes the exchange more honest.

Practice it on theChatStage

On theChatStage you choose a topic and a side, and when someone takes the other side you are matched. A live debate runs in real time. A turn-based debate has six written turns with 24 hours for each, and you can edit an argument until your opponent has answered it. Spectators can watch but not speak. You must be 16 or over to take part. Start with the topic list, pick the side you would normally avoid, and see what happens. Our guides to practicing arguing online and how a six-turn debate works go deeper.

Common questions

Is it dishonest to argue something I do not believe?

Not when it is an exercise and the format makes that clear. Lawyers, debate teams and philosophy students do it routinely. What would be dishonest is presenting the view as your personal belief when it is not.

What if I find I agree with the other side after all?

Then you learned something. You do not have to announce a change of mind in the debate, and you can keep or drop your original view afterwards.

Which topics are best for a first try?

Practical questions with concrete examples, such as education or work topics. They are easier to argue calmly than questions about identity or belief.
