Intergroup Behavior

Intergroup behavior involves the feelings, perceptions, beliefs, and actions that groups and their members have toward another group and its members. It frequently involves various forms of bias, such as prejudice (negative feelings and evaluations), stereotypes (beliefs about groups and their members), and discrimination (unfair treatment). However, intergroup bias does not necessarily require overtly negative orientations toward another group. Such bias may reflect favorable attitudes toward members of one’s own group (the ingroup) and preferential treatment of them, rather than hostility or ill-treatment of other groups (outgroups). Intergroup behavior can also be positive, representing cooperation (conduct and exchange that benefits both the ingroup and the outgroup) or prosocial behavior (actions that improve the welfare of another group and its members). The nature of intergroup behavior is determined by psychological processes associated with social categorization, by the identification and motivations of group members, and by the consequent relationship between groups. These processes apply to almost any type of group, including but not limited to work teams, divisions within an organization, companies, sport clubs, ethnic groups, countries, religions, and races. Understanding the psychological dynamics of intergroup relations can guide the development of interventions to achieve stable, constructive, and mutually beneficial exchanges between groups and their members.
