Minority influence: a meta-analytic review of social influence processes.

A meta-analytic review of 97 minority influence experiments evaluated the processes by which sources advocating deviant, minority opinions exert influence. Minority impact was most marked on measures of influence that were private from the source and indirectly related to the content of the appeal and less evident on direct private influence measures and on public measures. This attenuated impact of minorities on direct private and public measures suggests that in response to normative pressures, recipients avoided aligning themselves with a deviant source. Mediator analyses revealed that minorities perceived as especially consistent in the advocacy of their views were especially influential. The relation between normative and informational pressures in the minority influence paradigm was discussed.
