Social proof is a psychological model in which individuals determine appropriate behavior by observing what others do in uncertain or ambiguous situations. The mechanism operates as a decision heuristic: when internal criteria are absent or unreliable, people treat the actions of a reference group as evidence of the correct response. It persists through social learning, cultural transmission, and institutional messaging that signals which behaviors are normative. The model was formalized in social psychology through experiments on conformity and informational influence, and it operates as a measurable phenomenon in marketing, public health campaigns, and digital platform design.
