Group polarization describes the phenomenon that groups tend to make decisions that are more extreme than the initial inclinations of their members. This is because group members are influenced by each other's opinions and are more likely to conform to the group's dominant view. As a result, the group's final decision is often more extreme than any of the individual members' initial positions.
Group polarization can occur in both positive and negative directions. For example, a group of people who are initially in favor of a particular policy may become even more supportive of it after discussing the issue with each other. Conversely, a group of people who are initially opposed to a policy may become even more opposed to it after discussing the issue with each other.
Group polarization is a common phenomenon that can have a significant impact on decision-making. It is important to be aware of this phenomenon and to take steps to mitigate its effects when making group decisions.
