Group Polarization

This lecture covers the concept of group polarization, where group discussions lead individuals to make riskier decisions than they would alone, as shown in studies on decision-making and prejudice. The discussion process, the importance of initial divergence of opinions, and the influence of group dynamics on individual decisions are explored. The lecture also delves into the phenomenon of 'self-enhancement conformity', where individuals conform to group opinions but express them more strongly, enhancing their visibility and competence. The impact of group discussions on risk-taking behavior, the role of information exchange, normative influence, and pluralistic ignorance are discussed. Additionally, the lecture touches on the effects of extreme opinions within social media bubbles, leading to polarization and potentially antisocial behaviors.
