Robbers Cave04:49

Robbers Cave

14.2K
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...

Stereotypes, Prejudice, and Discrimination

89.9K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Bias01:22

Bias

3.7K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Confirmation Biases01:31

Confirmation Biases

5.4K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Bullying

8.4K
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

In- and Out-Groups

38.8K
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.

Summary

Exclusionary behavior varies globally, with some nations favoring exclusion and others inclusion. Individual traits like gender, reasoning style, and political leaning consistently predict exclusion, regardless of country.

Area of Science:

  • Social Psychology
  • Behavioral Economics
  • Cross-Cultural Studies

Background:

  • Exclusionary behavior, characterized by alliance formation to restrict resource access, is observed in primates and humans across various societal domains.
  • Despite its socio-economic significance, global prevalence and determinants of human exclusionary behavior remain under-researched.

Purpose of the Study:

  • To investigate the global prevalence and heterogeneity of exclusionary behavior in resource division.
  • To identify individual and cultural factors influencing exclusionary behavior across different countries.

Main Methods:

  • An experimental game involving resource division by majority rule was conducted across multiple countries.
  • Individual-level characteristics (gender, reasoning style, political ideology) and cultural factors (Hierarchy Tolerance Index) were analyzed.

Main Results:

  • Significant global heterogeneity in exclusionary behavior was observed, with exclusion being modal in some countries and inclusion in others.
  • Individual factors such as being male, possessing a deliberative reasoning style, and holding right-leaning political views consistently predicted higher exclusion.
  • Cross-country variations in exclusionary alliances correlated with cultural acceptance of power inequalities, as measured by the Hierarchy Tolerance Index.

Conclusions:

  • Decision-making processes are influenced by both individual characteristics and the cultural context, impacting resource equity.
  • Understanding these determinants is crucial for designing fairer resource allocation systems and inclusive decision-making bodies.
