Social identity theory proposes that people categorize themselves and others into social groups. People tend to favor the groups they belong to and view them more positively than other groups. Members of a group work to enhance the status and image of their group. There are two belief systems for improving one's social identity: social mobility, believing one can change groups to gain status; and social change, believing one must challenge the status quo since boundaries cannot be crossed. Understanding social identity theory can help create more effective music videos by appealing to the social identities and groups of the target audience.
