The outgroup is a group that people perceive as distinctively different from or apart from their ingroup.

In the context of psychology, an outgroup refers to any group with which an individual does not identify. This concept is critical in social psychology, particularly in the study of group dynamics, prejudice, and intergroup relations.


The concept of an outgroup is used to describe groups that individuals perceive as different or separate from their own, known as their ingroup. The differentiation between ingroup and outgroup can influence one's behavior, attitudes, and perceptions significantly. People tend to view members of an outgroup with suspicion, bias, or hostility, often leading to stereotyping and discrimination. This distinction plays a fundamental role in the development of group identity and can affect social cohesion and conflict.

Application Areas

Understanding outgroups is essential in various fields within psychology:

  • Social psychology: Examines the impact of outgroup perceptions on social identity, prejudice, and conflict.
  • Organizational psychology: Studies how ingroup-outgroup dynamics affect workplace cooperation and teamwork.
  • Political psychology: Explores how outgroup hostility or favoritism influences political behavior and attitudes.

Well-Known Examples

A well-known psychological experiment that illustrates the concept of outgroups is the Robbers Cave Experiment by Muzafer Sherif. In this study, groups of boys developed strong ingroup identities and exhibited significant hostility towards the outgroup, highlighting how quickly and easily outgroup discrimination can arise.

Treatment and Risks

In terms of social intervention and education, reducing outgroup prejudice is critical:

  • Educational programs: Aim to foster intergroup understanding and reduce stereotypes.
  • Diversity training: Used in corporate and educational settings to enhance awareness and integration.

Symptoms, Therapy, and Healing

  • Therapy Techniques: Interventions such as intergroup contact and dialogue are used to mitigate outgroup biases and improve relationships between diverse groups.
  • Healing Process: Efforts to bridge ingroup-outgroup divisions can lead to improved social harmony and reduced intergroup conflict.
