What is a drawback of group polarization?

Group polarization refers to the phenomenon where discussions within a cohesive group lead to the adoption of more extreme positions than those held individually by members prior to the discussion. This can occur because members reinforce each other's beliefs, leading to a shift toward a more radical perspective. The correct answer highlights this tendency toward more extreme positions, which can result in risky decisions or reinforced biases within the group.

In contrast, the other choices indicate outcomes that do not align with the dynamics of group polarization. For instance, less extreme opinions would represent a moderation of views, which contradicts the essence of polarization. Improved understanding among members suggests a collaborative and enlightening process, rather than the intensification of divisive views, while reduced group cohesion would imply fragmentation rather than the strong solidarity that often fosters polarization. Thus, the core aspect of group polarization that involves a shift to more extreme views is aptly captured in the chosen answer.
