Majority perspective and minority dissent creates conflict, but such conflict can give rise to minority influence over societal changes. We discuss psychological mechanisms by which a dissenting minority opinion can yield long-lasting changes in attitudes and behaviours. We discuss social conditions that could moderate whether minority influence is effective at converting majority members. Finally, even if minority influence effectively shifts majority attitudes and behaviours, minority groups still face unique intragroup challenges, such as majority and minority group destabilisation and discreditation of their efforts to effect social change.
