Why do People Form Social Identities?
A social identity is chosen membership in a social group or category. Most of the answers to the question: “who are you?” are social identities. In my case, if I say I am a man, a father, a husband, an immigrant, and so on, these are all examples of broader social categories which make up much of my identity. But notice the irony here–we need to identity with larger social groups in order to answer the question of who we are at a personal level.
