Woman: Social identity theory offers a compelling answer to this question. First, let me define the concept of social identity. Social identity refers to how you understand yourself in relation to your group memberships.

Michael Hogg, a professor of social psychology at Claremont University, focuses on social identity research. In his 2006 book on contemporary social psychological theories, Hogg explains that group affiliations provide us with an important source of social identity. And we therefore want our groups to be valued positively in relation to other groups. By affiliations, I simply mean the groups that we join and perhaps link to online.
