Findings of minority influence studies lack external validity and are limited in what they can tell about how minority influence works in real-life social situations
Martin et al. (2003) found that people were less willing to change their opinions if they had listened to a minority group rather than a majority group
Minority messages are more deeply processed and have a more enduring effect, supporting the central argument about how the minority influence process works
Limitation of minority influence research: tasks involved are artificial and far removed from real-life situations like jury decision making and political campaigning
