Social identity is concerned with individuals as a part of a social group, how they identify with that group, behave and adopt shared attitudes to outsiders. (Reicher et al., 2010): Identities are: relational, shared, active, derived from history and the present (Tajfel) and the minimal group studies. (Turner): how people use different multiple, intersectional, changing, salient categories to define themselves ReferencesAbrams, D. And Hoggs, M.
