Social Norms

Social norms are the informal rules that govern behavior in groups, enforced not by law but by the distributed sanctions of approval and disapproval. They solve coordination problems that formal contracts cannot reach — how close to stand in an elevator, how loudly to speak in a library, how promptly to reply to an email. Every norm is a Schelling point that has hardened into expectation through repetition, and every expectation carries the implicit threat of social punishment for violation.

The puzzle of social norms is not why people follow them but why people enforce them. The enforcer pays a cost — confrontation, social friction, cognitive load — for a benefit distributed across the group. This is itself a second-order collective action problem, and its solution requires that norm-enforcement be psychologically rewarding or reputationally profitable. The emotions of outrage, disgust, and righteous indignation are not bugs in human sociality. They are enforcement mechanisms that make norm maintenance self-sustaining without centralized authority.

The persistent assumption that norms are arbitrary conventions misses their function as distributed governance systems. A society without norms is not a society of free individuals — it is a society that has not yet solved its coordination problems, and will not survive long enough to do so.
