SUPERRATIONALITY — [Noun] A form of rational decision-making where players, recognizing mutual superrationality, choose cooperative strategies in dilemmas like the prisoner's dilemma, as opposed to game-theoretically rational defection. From super- ("above, beyond") + rationality ("reason-based decision-making"), coined by Douglas Hofstadter. Unlike "game-theoretic rationality" (which assumes players act independently, often to mutual detriment) or "bounded rationality" (which concedes human frailty), superrationality is the luminous exception—a pact of trust forged in the cold calculus of logic. It is the handshake between two minds that need not be forced, the unspoken agreement to split the last slice of cake, or the quiet decision to water a neighbor’s plants while they’re away, knowing they would do the same—proof that even in a world of selfish axioms, cooperation can be the highest form of reason.
