Durkheim's foundational methodological unit — a way of acting, thinking, or feeling external to the individual and endowed with coercive power, recognizable by the regularity with which it appears across populations independently of individual psychology.
Social facts are the objects of sociology. They are not reducible to the mental states of individuals, even though they exist only through individual action. They exhibit two defining characteristics: exteriority (they exist outside any particular individual, in the shared norms, expectations, and institutions of the collective) and constraint (they exercise coercive power over individual behavior, visible in the discomfort or sanction that follows their violation). The signature of a social fact is the statistical regularity with which a behavior appears across a population — the fact that suicide rates, marriage rates, and divorce rates exhibit patterns that no individual chose but that no individual can escape. Applied to the AI transition, the framework transforms what appears to be individual psychological distress — the builder's compulsion, the student's paralysis, the parent's oscillation — into the observable manifestations of a structural condition operating on individuals from outside.
