Theory of Rational Elasticity

A framework proposing that rationality—as a property of agents, beliefs, and actions—is elastic. Rational Elasticity suggests that what counts as rational can stretch across contexts without becoming irrational: a decision that's rational for you (given your goals, information, values) might not be rational for me, but both are within rationality's elastic range. The theory identifies the limits: when does stretching become irrationality? When does rational adaptation become rationalization? Understanding rationality requires understanding its stretch.

Theory of Rational Elasticity "To you, quitting your job was irrational; to me, it was the only sane choice. Rational Elasticity says we're both right—rationality stretches across different goals, different values, different contexts. The question isn't who's rational; it's whether we can stretch enough to see each other's reasons."
