Both-sides debate

Argue each side in turn and then judge, so your final view has survived contact with the case you didn't want to make.

When to use it

  • A contested question is coming up and you have only heard one side well.
  • You need a final view that has survived contact with the case you did not want to make.
  • An essay asks you to “evaluate” and you have been writing advocacy.

What to ask AI

Type something like: “Moderate a both-sides debate on: [question]. I must argue Affirmative first, then Negative, equal length.”

Ask it not to declare a winner until you have judged both cases yourself.

Keep writing both sides in your own words.

How it helps

Arguing only your preferred side rehearses loyalty, not judgment.

Both-sides debate forces you to build each case, then judge.

The learning happens in the judgment step: what survived contact with the unwanted case?

Without that step, you just performed twice.

How to run it

  1. Name a contested question with two real sides.
  2. Argue side A at full strength for a set word budget.
  3. Argue side B at full strength for the same budget.
  4. Judge in writing: which reasons survive, and what is your revised view?
  5. Only then ask the AI to critique your judgment, not to replace it.

Example exchange

You

Can you moderate a both-sides debate on whether first-year courses should ban generative AI? I’ll write both sides.

AI

Affirmative first, strongest case for a ban. I won’t tip the scales.

You

Affirmative: a ban protects skill formation when novices can’t yet judge AI output, keeps assessment honest, and forces early writing practice without autocomplete crutches.

AI

Now Negative, equal strength, no strawmen.

You

Negative: bans are unenforceable, hide a skill students will need at work, and punish honest users while cheaters still find tools. Better to redesign assessment than pretend the tools vanished.

AI

Your turn to judge, which reasons survive on both sides, and what’s your revised position?

Copyable prompt

Moderate a both-sides debate on: [QUESTION]. Rules: I must argue Side
Affirmative first, then Side Negative, equal length. Do not declare a winner.
After both, ask me for my judgment and critique only that.

The Tell

If after “debating both sides” your prior view is untouched and unexamined, you performed advocacy twice.

If the AI crowned a winner before you judged, restart and keep the judgment yours.

Principle evidence

Strength of the underlying learning idea, not a claim about AI products.

The underlying learning idea is rated weak-to-moderate. Both-sides debate is common pedagogy; evidence that it reliably improves judgment (rather than polarisation or false balance) is mixed. The judgment step is load-bearing.

AI delivery evidence

Whether an AI tutor delivers this method well is a separate question.

AI moderation can smuggle a preferred side. Keep the verdict yours. Delivery is speculative.
