According to social identity theory, people tend to categorize each other into groups and then show favoritism to their own group.
The social identity of a person reveals who they are in terms of the groups they are a part of. Social identity groups are typically described by some of an individual's physical, social, and mental traits. Based on the inherent value that people place on belonging to social groups and their desire to see their particular social groups in a positive light, social identity theory (SIT) offers a framework for explaining intergroup behavior and intergroup communication. Conflict and intergroup prejudice may result from this desire. Three crucial cognitive processes—social categorization, social identification, and social comparison—form the basis of social identity theory. People typically want to preserve their group's favorable social standing over that of relevant out-groups in order to preserve their positive social identity.
