Across two preregistered studies with children (3-12-year-olds; N = 356) and adults (N = 262) from the United States, we find robust expectations for intergroup empathic biases. Participants predicted that people would feel better about ingroup fortunes than outgroup fortunes and worse about ingroup misfortunes than outgroup misfortunes. Expectations of empathic bias were stronger when there was animosity and weaker when there was fondness between groups. The largest developmental differences emerged in participants' expectations about how others feel about outgroup misfortunes, particularly when there was intergroup animosity. Whereas young children (3-5-year-olds) generally expected people to feel empathy for the outgroup (regardless of the relationship between the groups), older children (9-12-year-olds) and adults expected Schadenfreude (feeling good when an outgroup experiences a misfortune) when the groups disliked one another. Overall, expectations of empathic biases emerge early but may be weaker when there are positive intergroup relationships. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
