Group Polarization and Repeated Attitude Expressions: A New Take on an Old Topic

The empirical and theoretical literature on group polarization has concentrated on the persuasive arguments and normative positions that one receives from others in group settings. The research that we review in this article suggests that individuals polarize in group discussions in part because they frequently express their own opinions and arguments as well as listen to the arguments and opinions of other group members. Our work shows that repeated attitude expression is partially responsible for group polarization. Additionally, this effect is augmented when others in the group repeat and validate the arguments one has made. The discussion identifies the ways in which the results are consistent with or suggest modifications of the existing theories of group polarization.
