Yazdi, Haleh; Barner, David; Heyman, Gail D. – Child Development, 2020
Children generally favor individuals in their own group over others, but it is unclear which dimensions of the out-group affect this bias.

Across 2 studies, 7- and 10-year-olds from the United States and China (N = 334) judged the credibility of academic evaluations that were directed toward an unfamiliar peer. In Study 1, participants from China responded that…
