Question

If a group debates a controversial issue,when is "group polarization" likely to occur?​

Quizplus · Accepted Answer

Group polarization occurs when individuals within a group with similar views and attitudes on a controversial issue become more extreme and entrenched in those views after discussing the issue with each other. If most group members lean the same direction at the start of the discussion, the discussion is likely to reinforce and strengthen their existing opinions, leading to polarization. On the other hand, if the group has highly diverse opinions at the start of the discussion, the group is less likely to experience group polarization as individuals are exposed to a broader range of perspectives. Knowing each other well or being well informed about the topic may or may not contribute to group polarization.
