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.
The polemical force of the concept in the 1890s was its insistence that sociology is a science with its own subject matter, not reducible to psychology or biology. Durkheim's methodological stand was ontological: if social facts are real — distinct from and not reducible to individual minds — then sociology has a domain of explanation that no other discipline can provide. If they are not real, sociology collapses.
The evidence Durkheim marshaled was statistical. Suicide rates in Catholic regions were systematically lower than in Protestant regions. Marriage rates rose and fell with economic cycles. Divorce rates varied with the stringency of divorce law. These regularities could not be explained by individual psychology, because the individuals varied in every imaginable way while the rates persisted. The rates were properties of the social system, not the individuals composing it.
The AI transition produces social facts of exactly this kind. The behavioral signatures of anomie — compulsive working, directional paralysis, the erosion of temporal boundaries between work and non-work — appear with statistical regularity across populations exposed to AI-augmented work, independently of individual temperament or circumstance. The regularity is the evidence that the distress is structural rather than personal, and the methodological move required is the same one Durkheim insisted on: treat social facts as things, and explain them by other social facts rather than by individual choice or failure.
The ethical consequence is direct. If AI-era distress is a social fact, then the individualist response — "learn to manage your relationship with the tool" — is structurally inadequate. Social facts require social responses: institutional construction, normative regulation, collective deliberation. The professional group, the beaver's dam, the organizational dam — each is a response at the appropriate ontological level.
The concept was formalized in The Rules of Sociological Method (1895), the methodological treatise Durkheim published to establish sociology as an autonomous discipline. The book's central injunction — treat social facts as things — has been read as both realist metaphysics and methodological stance, and the ambiguity has sustained generations of debate about what exactly Durkheim claimed.
The empirical vindication of the framework came in Suicide (1897), which demonstrated that even the act apparently most individual — the decision to end one's own life — exhibits population-level regularities explicable only by social forces. The book remains a model of how to deploy the concept of social fact in empirical research.
Two defining characteristics. Exteriority (beyond any individual) and constraint (coercive over individual behavior) together define the social fact.
Statistical regularity is the signature. When a behavior appears with regularity across a population, despite individual variation, the regularity indexes a social fact.
Distress can be a social fact. The regular appearance of the same psychological pattern across populations exposed to the same structural conditions is the empirical marker.
Requires social response. Social facts are not solved by individual willpower; they are addressed by institutional construction at the ontological level where they exist.
The foundation of Durkheim's sociology. Without the reality of social facts, sociology reduces to psychology; the methodological stand is also a metaphysical one.
