Pluralistic ignorance
In social psychology, pluralistic ignorance is a situation in which a majority of group members privately reject a norm, but go along with it because they incorrectly assume that most others accept it. This is also described as "no one believes, but everyone thinks that everyone believes". In short, pluralistic ignorance is a bias about a social group, held by the members of that social group.
Pluralistic ignorance
Pluralistic ignorance has been linked to a wide range of deleterious consequences. For example, victims of pluralistic ignorance see themselves as deviant members of their peer group: less knowledgeable than their classmates, more uptight than their peers, less committed than their fellow board members, less competent than their fellow nurses (see the Dunning–Kruger effect operating in the opposite direction). This can leave them feeling bad about themselves and alienated from the group or institution of which they are a part. In addition, pluralistic ignorance can lead groups to persist in policies and practices that have lost widespread support: This can lead college students to persist in heavy drinking, corporations to persist in failing strategies, and governments to persist in unpopular foreign policies. At the same time, it can prevent groups from taking actions that would be beneficial in the long run: actions to intervene in an emergency, for example, or to initiate a personal relationship.
