  • Title:
    Group Polarization: A Critical Review and Meta-Analysis
  • Author / Creator: Isenberg, Daniel J.
  • Summary: This article critically reviews recent (1974–1982) group polarization studies that address themselves to either one of the two primary explanatory mechanisms thought to underly group polarization, namely social comparison and persuasive argumentation processes. A summary of the effect sizes of 21 published articles (33 independent effects) suggests that social comparison and persuasive argumentation occur in combination to produce polarization, although the persuasive argumentation effects tend to be larger. Attempts are made to reconcile the two positions, and some suggestions for further research are offered.
