Social Identity Theory

Social Identity Theory elucidates the manner in which individuals characterize themselves by their affiliations with social groupings, such as family, nation, or team. Tajfel and Turner first suggested this idea in the 1970s. It says that people get some of their self-esteem and self-concept from being a part of a community. When individuals have a strong identification with an in-group, they often exhibit preferential treatment towards it, resulting in in-group favoritism and the possibility of out-group bias. This group-based identity affects how people see themselves and others.

 Some important parts of Social Identity Theory are:

Social categorization: others put themselves and others into categories based on things they have in common, such race, religion, interests, and so on. This makes it easier to understand others.

 Social identification: People follow the rules and act like the groups they belong to, and their values and behavior change to match those of the group.

 Social comparison: Once individuals have put themselves into groups and named them, they typically compare their group to other groups in ways that make their group look better. This might make people feel better about themselves, but it can also lead to stereotypes and bias.

Social Identity Theory elucidates several group phenomena, including patriotism, ethnic strife, and brand loyalty. For example, emphasizing a superordinate identity (a bigger common group) helps lessen friction between groups. In companies, executives employ these principles to bring people together by creating a strong sense of who they are as a group. Understanding SIT is useful for things like marketing (building communities of customers) and social policy (bridging party differences).
