Social identity theory

Social identity is the part of a person's self-concept that is made from their membership in a social group.

Social Identity theory tries to explain inter-group behaviours as a result of...

  • difference in status within the group
  • legitimacy and stability of the status differences
  • ability to move to another group


  • In-group Favouritism
  • Help other people in the group
  • Reluctance to bet against the group even if they are negatively affected by it.
