What Are Social Norms?

(With Franz Dietrich). Updated June 2025. Draft.

Most recent theorists take social norms to arise from certain attitudes, such as expectations on others, perhaps along with conforming practices. Challenging this view, we argue that social norms are instead grounded in a social norming process: an (often non-verbal) social communication process that institutes or ‘makes’ the norm. We present different versions of a process-based account of social norms and social normativity. The process-based view brings social norms closer to legal norms, by taking social norms to arise through ‘expressive acts’, just as some laws and contracts arise through acts of voting or signing, not through mere attitudes. Social norms should be distinguished from social pressures, which often co-exist with social norms but are caused by attitudes.
