The insight that what counts as "rational" behavior is defined by cultural and historical context. Maximizing personal profit is "rational" in neoliberal economics. Sacrificing oneself for one's community is "rational" in a honor-based society. Rationality is not a universal calculator in the brain; it's a set of culturally constructed goals and acceptable means that we learn and perform.
Example: "My boss said turning down a promotion to care for my dad was 'irrational.' My family said it was the only honorable choice. The Theory of Constructed Rationality explains the clash: we were using different construction manuals. His manual defined rationality as individual career maximization. Mine defined it as fulfilling familial duty. Neither is 'natural'; both are learned scripts for sensible action."
