Group identity refers to the recognition of the group as a distinct unit by both members and nonmembers. Group identity is a critical part of a group’s well-being and much of the behavior of a group will serve to promote and maintain group identity. For example, specific rituals, forms of dress, and speech patterns can help distinguish group members from nonmembers and thus promote group identity. We see this with teenage cliques, religious groups, and even military regiments.
