- Sociology
- Developmental Science
Background:
- Children are increasingly victims of exclusion, discrimination, and prejudice based on race, ethnicity, nationality, and religion.
- Intergroup biases, the tendency to favor one's own group, emerge in early childhood, preceding formal schooling.
- These early biases contribute to systemic racism and discrimination extending into adulthood.
Purpose of the Study:
- To review evidence on the emergence of intergroup biases in childhood.
- To analyze the role of intergroup friendships in children's wellbeing and prejudice reduction.
- To highlight the impact of early biases on long-term societal issues.
Main Methods:
- Literature review synthesizing research on childhood intergroup bias.
- Analysis of studies focusing on race, nationality, and religion.
- Examination of the impact of cross-group friendships on children.
Main Results:
- Children exhibit intergroup biases before entering grade school.
- Intergroup friendships are shown to enhance children's wellbeing.
- Positive cross-group interactions reduce prejudice in childhood.
Conclusions:
