Robbers Cave04:49

Robbers Cave

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension could be...
In- and Out-Groups01:31

In- and Out-Groups

People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.
Impact of Groups on Groups01:19

Impact of Groups on Groups

Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...
Group Polarization01:01

Group Polarization

Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.
The Stanford Prison Experiment03:20

The Stanford Prison Experiment

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.
Self-Help Support Groups01:28

Self-Help Support Groups

Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems.

Summary

Majority group members may support separatist movements when perceiving a threat to national identity continuation. This study reveals a potential for peaceful responses to separatism, mediated by continuation threat.

Area of Science:

  • Social Psychology
  • Political Psychology
  • National Identity Studies

Background:

  • Separatism is prevalent but understudied in psychology, with majority responses largely ignored.
  • Existing research overlooks the psychological impact of separatist movements on national identity and majority perceptions.

Purpose of the Study:

  • To investigate majority group responses to separatist movements.
  • To examine whether perceived threats to national identity or economic position influence support for separatist groups.
  • To test the hypothesis that continuation threat, not economic threat, drives majority support for government measures aiding separatists.

Main Methods:

  • Two studies were conducted with Javanese students (N=322 in Study 1, N=180 in Study 2).
  • Participants were induced to believe separatist movements in West Papua or Aceh were either increasing or dormant.
Keywords:

  • Support for government measures aiding separatist groups was measured, along with perceived continuation and economic threats.

    • Main Results:

    • Belief in increasing separatist activity led to greater support for separatist groups.
    • This effect was mediated by perceived continuation threat, but not economic threat.
    • Findings suggest a psychological pathway where threats to national identity continuation can foster support for separatist groups.

    Conclusions:

    • Majority group responses to separatism are psychologically driven by threats to national identity continuation.
    • Perceived threats can lead to unexpected support for government measures assisting separatist groups.
    • This research highlights a potential for peaceful conflict resolution by addressing majority group concerns about national identity.
