Minority Influence

🧠 Psychology By CampusDown Wiki Editorial Team Last updated October 27, 2026

Minority influence is the social psychological finding that a numerical minority holding a consistent, confident position can change the opinions or judgements of a majority. Serge Moscovici developed it as a counterweight to conformity research focused on majority pressure.

The consistent minority

After Asch's conformity studies, Moscovici and colleagues (1969) showed two confederates consistently calling blue slides green shifted majority responses, but only when consistent.

Conversion theory

Moscovici (1980) argued majorities produce public compliance while minorities trigger scrutiny and later private conversion. Nemeth (1986) found minority dissent spurs divergent thinking, countering groupthink.

Evidence and extensions

Wood and colleagues (1994) found larger effects on private, indirect measures; Mugny (1982) stressed flexible negotiation styles; Martin and Hewstone (2008) offered an integrative model, with group membership mattering per social identity theory.
