Social identity theory

Social identity theory is a theory in social psychology that explains how individuals develop a sense of identity based on the groups they belong to. According to this theory, people define themselves in terms of their group memberships and derive pride and self-esteem from those group affiliations. This can lead to in-group favoritism, where individuals show preference for their own group over other groups, and out-group discrimination, where individuals exhibit negative attitudes and behaviors towards members of other groups.

The theory also posits that individuals will strive to enhance the status and image of their in-group in order to boost their own self-esteem. This can manifest in behaviors such as promoting the achievements of the in-group, defending the group from criticism, and seeking out similarities with other group members.

Overall, social identity theory helps to explain how group memberships shape individuals' identities, attitudes, and behaviors, and how these dynamics can contribute to intergroup conflict and prejudice.
