Minority influence: the role of the rate of majority defection and persuasive arguments

An experiment employing the Twelve Angry Men paradigm was conducted to determine the role of the rate of majority defection to the minority position and the use of persuasive arguments by the minority on minority influence. Subjects were more influenced by the minority when it provided persuasive arguments by refuting the majority viewpoint than when the minority did not. More minority influence occurred when the minority obtained majority defectors than when the minority did not. Moreover, the rate of majority defection made a difference. Minority influence was not obtained with the initial acquisition of a single defector and the significant influence that occurred with the acquisition of four defectors was not further increased by the acquisition of additional defectors. The results for the number of majority defectors were generally consistent with Tanford and Penrod's social influence model. Finally, the issue of the number of majority defectors versus the speed at which they defect is discussed. (C) 1998 John Wiley & Sons, Ltd.
