P: Martin et al (2003) gave ppt message supporting particular viewpoint, & attitudes measured. Then they heard endorsement of view from either minority or majority. Finally, they heard conflicting view: attitudes measured again.
E: People less willing to change their opinions to new conflicting view if they had listened to minority group than if they listened to a majority group.
L: Suggest the minority message had been more deeply processed & had more enduring effect.
