Developmental perspectives on prejudice provide a fundamental and important key to the puzzle for determining how to address prejudice. Research with historically disadvantaged and advantaged groups in childhood and adolescence reveals the complexity of social cognitive and moral judgments about prejudice, discrimination, bias, and exclusion. Children are aware of status and hierarchies, and often reject the status quo. Intervention, to be effective, must happen early in development, before prejudice and stereotypes are deeply entrenched.

The inherence heuristic: a key theoretical addition to understanding social stereotyping and prejudice

Prior work has detailed the constructivist processes that lead individuals to categorize others along particular dimensions (e.g., gender) and generate the content (e.g., stereotypes) and affect (e.g., prejudices) associated with social groups. The inherence heuristic is a novel mechanism that appears to shape the content and rigidity of children's social stereotypes and prejudices.

Inherence-based views of social categories.

Children adopt an inherence-based view of some social categories, viewing certain social categories as reflecting the inherent features of their members. Thinking of social categories in these terms contributes toprejudice and intergroup conflict. Thus, understanding what leads children to apply inherence-based views to particular categories could provide new direction for efforts to reduce these negative social phenomena.
