Most people treat disagreement as a problem to be resolved. The Nyāya school of ancient Indian philosophy had a different view: they developed one of the world's most rigorous formal theories of debate, not to win arguments, but to use opposition as a precision instrument for refining your own thinking. Their term for it was *vitandā* — a mode of disputation where you temporarily argue the opposite of what you believe, not to be contrarian, but to stress-test your position until only what is genuinely defensible survives. Modern political scientist Philip Tetlock found something structurally similar in his decades-long 'forecasting tournament' research: the people who were most accurate in predicting complex world events weren't those who held beliefs confidently — they were those who actively recruited counter-arguments and treated their own views as provisional hypotheses. The practical upshot is uncomfortable: the belief you defend most passionately in conversation is probably the one least examined. Try this today — pick one conviction you haven't questioned in months and spend five minutes arguing sincerely against it.

What would someone who genuinely disagreed with your most defended position say — and have you ever let that argument run to its conclusion without interrupting it?
