Social Comparison and Persuasive Arguments as Determinants of Group Polarization

In a study of group polarization, Bosier and Mayer (1984) found that social comparison information influenced perception of persuasive argument information. In their investigation, however, position of majority was confounded with other of presentation. The present study attempted to replicate Boster and Mayer while varying order of presentation. Results of the present investigation, first, support the persuasive arguments explanation of group polarization. Second, results are inconsistent with an order effect. Finally, results indicate a parallel between the group polarization literature and the cognitive response literature in persuasion.
