Mental Heuristics

Mental heuristics are cognitive shortcuts — compressed decision procedures that sacrifice formal optimality for computational efficiency. They are the operating system of everyday cognition: fast, cheap, and reliable within their domain of competence. The field of cognitive bias research emerged precisely from studying what happens when heuristics are applied outside their domain. Calling heuristics "irrational" misses the point: they are rational under resource constraints, and their failures are not bugs but boundary conditions. The deeper question is what ecological rationality looks like — how heuristics are calibrated to their environment — and whether modern information environments have become systematically miscalibrated for the heuristics evolution provided.
