But how does it develop? Adopting a sociocultural lens to the development of intergroup bias among children.

We argue that adopting a sociocultural lens to the origins of intergroup bias is important for understanding the nature of attacking and defending behavior at a group level. We specifically propose that the potential divergence in the development of in-group affiliation and out-group derogation supports De Dreu and Gross's framework but does indicate that more emphasis on early sociocultural input is required.
