According to social identity theory, individuals define themselves in relation to others based on a "self-identity" or "social identity" factor and form binding relationships with people who categorize themselves similarly.

Explanation:

The theory of social identity, proposed by Henri Tajfel and John Turner, aims to explain how an individual defines their position in society. The objective of this theory is to analyze and understand  the  processes by  which  people  classify themselves into social categories.

Social identification allows individuals to behave in a similar way to other members of the same group. The individual characteristics of a person and her/his relationships play a significant role in shaping values, beliefs, and behavior. For instance, if a person is very conservative, he or she will share these beliefs with people with similar interests and behavior. According to the theories of social identity and self‐categorization, this behavior will highly influence another person's self-identity within a group.
