Answer :
Students who join extracurricular groups on campus tend to see their attitudes regarding the groups' purpose increase if they stay in the group. This is an example of group polarization.
When "members of a deliberating group migrate toward a more extreme position in whatever direction is signaled by the members' predeliberation inclination," this is referred to as group polarisation. Individuals inside the group experience attitudinal changes as a result of group polarisation.
Additionally, group polarisation can result in groupthink, which is when a group makes poor decisions because some of its members are afraid to voice their thoughts or propose novel ideas that some members of the group might find objectionable.
