Theory of Constructed Rationality

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."

Theory of Rationality Constructions

The theory that rationality itself is constructed—that what counts as reasonable, logical, or rational varies across contexts and is shaped by social, cultural, and historical forces. Rationality Constructions argues that there is no single, universal standard of reason—only different communities with different norms, developed for different purposes, serving different interests. This doesn't mean reason is arbitrary; it means reason is plural, that different rationalities exist, that the question isn't "is it rational?" but "rational by whose standards?" The Theory of Rationality Constructions explains why cross-cultural communication is hard, why debates about reason never end, why what seems obvious to one person seems absurd to another. Rationality is constructed, not given—and constructed things can be contested.

Theory of Rationality Constructions Example: "He couldn't understand why his arguments didn't convince people from different backgrounds. The Theory of Rationality Constructions explained: they were using different rationalities, different standards, different norms. His logic was logical in his framework; theirs was logical in theirs. Neither was wrong; they were just differently constructed. Understanding didn't win arguments, but it stopped him from calling them irrational."
