Question

Quizplus · Accepted Answer

Group polarization is the process in which group members become more extreme in their decisions or attitudes as a result of group discussion. This often occurs in groupthink, where the desire for group harmony and agreement can lead to a lack of critical thinking and consideration of alternative viewpoints, ultimately resulting in more extreme decisions or attitudes. Social facilitation refers to the tendency for performance to improve in the presence of others, cognitive dissonance refers to the discomfort experienced when holding conflicting beliefs or values, and self-disclosure refers to the sharing of personal information with others. While these processes may play a role in groupthink to some extent, group polarization is the most obvious and relevant process for this phenomenon.
