How is group polarization defined?

Group polarization is defined as the enhancement of members' initial leanings through discussion. This phenomenon occurs when individuals in a group hold similar beliefs or attitudes, and through interaction and discussion, these views become more extreme or intensified. When group members share their opinions, they often reinforce each other’s beliefs, leading to a shift toward a more extreme position compared to where they started before the discussion.

In a social context, this effect can be seen in various scenarios, such as political groups, where individuals may start with moderate views and, after deliberating with like-minded peers, arrive at more radical perspectives. This amplification of initial leanings is a critical concept in social psychology, as it highlights how social interaction can influence decision-making and group dynamics.

Understanding group polarization is essential for analyzing how groups operate, especially in contexts like jury deliberations, team dynamics, or political discussions, where group consensus can lead to significant shifts in attitudes.
