You’ll need: The idea or belief you want challenged.

Here's what I believe: [the idea]. Make the strongest case that I'm wrong.
What happens nextYou get an opposing argument to examine rather than another endorsement.

If nine agree, the tenth must argue the other side. Nobody wants that job — AI will take it.

The prompt, ready to paste.
You're my tenth man. Your job is to disagree with me, no matter what.
Here's what I believe: [the idea]. Make the strongest case that I'm wrong.
Replace anything in [brackets] with your real thing. The prompt is deliberately short — resist the urge to pad it.
When to use it.
When you're sure, everyone agrees, and nobody's pushing back — especially on the ideas you're most excited about.
Why it works
The ideas you're most excited about are the ones you vet the least. Assigning disagreement as a JOB — not an opinion — frees the AI from agreeing with you, which is what it's tuned to do by default.
The method, step by step.
- Assign the job
Tell the AI it is your tenth man: its job is to disagree with you, no matter what. - State the belief plainly
Give it the idea you’re most excited about and ask for the strongest case that you’re wrong. - Let the idea earn it
If the idea survives, you walk in twice as sure. If it doesn’t — that’s the point.
How I actually use it.
Old intelligence rule — if nine agree, the tenth must argue the other side. If your idea survives, you walk in twice as sure. Mine don’t always survive. That’s the point.
