What aspect of self-concept is defined as the "we" part that comes from group memberships?

The aspect of self-concept defined as the "we" part that comes from group memberships is social identity. Social identity theory, developed by Henri Tajfel and John Turner, posits that a significant portion of an individual's self-concept is derived from the groups to which they belong. This could include groups based on various factors such as nationality, religion, social class, or any other social groups that impact a person's identity.

Social identity emphasizes the connection between an individual's self-perception and their relationships with these groups, illustrating how these affiliations shape attitudes and behaviors. It highlights the importance of belonging and the role of social groups in an individual's overall sense of self, which is crucial for understanding social behavior and group dynamics. This contrasts with personal or individual identity, which focuses more on personal traits and experiences. Cultural identity and individual identity also prioritize different aspects of the self, but social identity specifically encapsulates the collective nature of group memberships. Therefore, social identity is fundamentally linked to the "we" aspect of self-concept.
