Ingroup Favoritism Overview

Jul 23, 2025

Overview

This lecture explores ingroup favoritism—our tendency to favor people from our own groups over others—and examines its causes, outcomes, and personality/cultural influences.

Causes and Nature of Ingroup Favoritism

  • Ingroup favoritism is an evolutionarily functional tendency to prefer people like ourselves and distrust outgroups.
  • Social categorization leads to dividing people into ingroups (us) and outgroups (them), shaping perceptions and behaviors.
  • Even arbitrary and meaningless group divisions produce ingroup favoritism, as shown in Tajfel’s minimal group studies.
  • Ingroup favoritism arises from self-concern; positive feelings about our groups enhance self-esteem (social identity).

Outcomes and Manifestations of Ingroup Favoritism

  • Ingroup favoritism appears early in childhood and increases up to age six.
  • People rate ingroup members more positively and remember their successes over failures.
  • Negative or undesirable actions by ingroup members are often blamed on individuals, not the group as a whole.
  • Outgroup members’ negative behaviors are attributed to their group, while positive behaviors are dismissed as exceptions.
  • The group-serving bias (ultimate attribution error) reinforces ingroup positivity and outgroup negativity.

Limits and Exceptions to Ingroup Favoritism

  • Ingroup favoritism is reduced when the ingroup has low status or is clearly inferior in important ways.
  • The black sheep effect occurs when deviant ingroup members are judged more harshly than similar outgroup members.

Personality and Cultural Influences

  • People who highly value group membership (high collective self-esteem) display more ingroup favoritism.
  • Authoritarian individuals prefer simplicity, traditional values, and show more ingroup favoritism.
  • Social dominance orientation (SDO) describes a preference for group-based inequalities and predicts greater favoritism.
  • People with higher humanism and desire to control prejudice exhibit less ingroup favoritism.
  • Collectivist cultures, such as Chinese, show more group-based stereotyping than individualistic cultures, such as the USA.

Key Terms & Definitions

  • Ingroup Favoritism — Tendency to respond more positively to people from our own group than to outsiders.
  • Group-serving Bias — Attributing positive traits to the ingroup and negative traits to the outgroup.
  • Social Identity — Positive self-esteem derived from group memberships.
  • Black Sheep Effect — Strong devaluation of ingroup members who threaten the group’s image.
  • Authoritarianism — Preference for simplicity, traditional values, and conventional group distinctions.
  • Social Dominance Orientation (SDO) — Acceptance of inequality among different social groups.
