A meta-analytic review of 97 minority influence experiments evaluated
the processes by which sources advocating deviant, minority opinions e
xert influence. Minority impact was most marked on measures of influen
ce that were private from the source and indirectly related to the con
tent of the appeal and less evident on direct private influence measur
es and on public measures. This attenuated impact of minorities on dir
ect private and public measures suggests that in response to normative
pressures, recipients avoided aligning themselves with a deviant sour
ce. 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 mi
nority influence paradigm was discussed.
