Identity (social science)
Collective identity

Many people gain a sense of positive self-esteem from their identity groups, which furthers a sense of community and belonging. Another issue that researchers have attempted to address is the question of why people engage in discrimination, i.e., why they tend to favour those they consider a part of their "in-group" over those considered to be outsiders. Both questions have been given extensive attention by researchers working in the social identity tradition. For example, in work relating to social identity theory, it has been shown that merely crafting cognitive distinction between in- and out-groups can lead to subtle effects on people's evaluations of others.

Different social situations also compel people to attach themselves to different self-identities which may cause some to feel marginalized, switch between different groups and self-identifications, or reinterpret certain identity components. These different selves lead to constructed images dichotomized between what people want to be (the ideal self) and how others see them (the limited self). Educational background and occupational status and roles significantly influence identity formation in this regard.
