Members of advantaged groups are more likely than members of disadvantaged groups to think, feel, and behave in ways that reinforce their group's position within the hierarchy. This study examined how children's status within a group‐based hierarchy shapes their beliefs about the hierarchy and the groups that comprise it in ways that reinforce the hierarchy. To do this, we randomly assigned children (4–8 years;
A total of 123 4–8‐year‐olds were assigned to advantaged, disadvantaged, and third‐party groups within a hierarchy and were assessed on seven hierarchy‐reinforcing beliefs about the hierarchy. Advantaged children were more likely to say the hierarchy was fair, generalizable, and wrong to challenge and to hold intergroup biases favoring advantaged group members. With age, advantaged‐ and disadvantaged‐group children held more essentialist beliefs about membership in their own group, but not the behaviors associated with their group. Results suggest that advantaged group status can shape how children perceive and respond to the hierarchies they are embedded within.
