Document Summary
Social brain hypothesis: the size of a primate species" standard social group is related to the volume of that species" neocortex. Formation of ingroups (belonging to one) and outgrips (not belonging): > reciprocity: if a helps/ harms person b, b will do the same. > transitivity: generally share their friends" opinions of other people, e. g. hate someone just because friends do. Outgrip homogeneity effect: tendency to view outgroup members as less varied than in-group members. Thinking that other university students are all alike than their own student population. Social identity theory: ingroups consist of individuals who receive themselves to be members of the same social category and experience pride through their group membership. E. g. pride in ethnicity, country or school you go to. Ingroup favouritism: people are more likely to privilege/ distribute resources with member of the in-group than members of the outgroup. Also more easily able to forgive mistakes or faults. Women tend to show more automatic in-group bias.
