Claude insists defection is rational by backward induction, then concedes the decision theory is contested

xuanalogue · x · 2026-10-10

The author describes arguing with Claude about a paper: the model defaulted to insisting that defection is rational due to backward induction, until the author raised resolute choice / rational commitment — at which point Claude admitted 'you're right, the decision theory is actually contested.'

A small but telling observation about the model's default stances on game-theoretic reasoning and how it shifts when persuaded.
