Adults prefer fair processes ("procedural justice") over equal outcomes ("distributive justice"). This preference impacts their judgments of others in addition to their willingness to cooperate, raising questions about whether similar preferences drive judgments and behavior in children. The present study examines the development of this preference for procedural justice by testing children's attitudes towards procedural justice using a resource allocation task in both first- and third-party contexts, and in contexts in which the procedurally just process does versus does not create distributional injustice. Results from children 4 to 8 years of age demonstrate that children robustly attend to and prefer procedural justice over distributive justice. However, younger children are less likely to prefer methods that are procedurally just or that create distributively just outcomes in first-party contexts, when distributive injustice might favor them. Results suggest an interplay between abstract justice concerns and the emerging ability to override selfishness.
