Overhearing Brief Negative Messages Has Lasting Effects on Children's Attitudes Toward Novel Social Groups.

Societies are rife with out-group discrimination and mistreatment. One way that children might acquire social biases that lead to such outcomes is by overhearing derogatory or disparaging comments about social groups. Children (n = 121) overheard a video call between a researcher and an adult or child caller who made negative claims (or no claims) about a novel social group. Immediately and following a 2-week delay, older children (7-9 years) who overheard the message demonstrated stronger negative attitudes toward the group than children who heard no message. Younger children's (4- to 5-year-olds') attitudes were generally unaffected by these claims. Thus, overhearing brief, indirect messages from children or adults had robust and lasting effects on the social biases of children 7 years and older.
