Ingroup bias does not influence inequity aversion in children

Area of Science:

• Developmental Psychology
• Social Psychology
• Cognitive Science

Background:

• Ingroup favoritism can influence third-party norm enforcement, leading to leniency towards ingroup members.
• Group bias effects are less consistent in two-party contexts where individuals are direct victims of unfairness.
• Understanding the developmental origins of group bias and fairness norm enforcement is crucial for intergroup cognition theories.

Purpose of the Study:

• To empirically investigate the relationship between ingroup bias and fairness norm enforcement in children.
• To determine if and how group bias influences children's costly endorsement of fairness norms.
• To examine developmental differences in the emergence of group bias and fairness enforcement.

Main Methods:

• Utilized a minimal groups manipulation to induce ingroup bias in 6- to 9-year-old children.
• Assessed children's willingness to reject disadvantageous and advantageous resource allocations.
• Tested allocations involving both ingroup and outgroup members.

Main Results:

• Ingroup bias did not significantly affect children's rejection of unfair resource allocations.
• Children perceived unfairness more negatively when an outgroup member received more resources.
• Findings suggest children's endorsement of equality norms is indiscriminate and not influenced by group bias.

Conclusions:

• Ingroup bias does not appear to influence children's costly enforcement of equality norms.
• Children may view equality as a universal norm, enforceable across group boundaries.
• Early development of fairness norm enforcement may be independent of ingroup favoritism.
