Japanese‐American confinement and scientific democracy: Colonialism,social engineering,and government administration

During World War II, the U.S. Indian Service conducted social science experiments regarding governance among Japanese Americans imprisoned at the Poston, Arizona, camp. Researchers used an array of techniques culled from anthropological culture and personality studies, psychiatry, psychology, medicine, and public opinion research to probe how the personality traits of the confined Japanese‐Americans and camp leaders affected the social interactions within each group and between them. The research drew on prior studies of Indian personality in the US Southwest, Mexico's Native policies, and indirect colonial rule. Researchers asked how democracy functioned in contexts marked by hierarchy and difference. Their goal was to guide future policies toward US “minorities“ and foreign races in post‐war occupied territories. We show how researchers deployed ideas about race, cultural, and difference across a variety of cases to create a universal, predictive social science, which they combined with a prewar romanticism and cultural relativism. These researchers made ethnic, racial, and cultural difference compatible with predictive laws of science based on notions of fundamental human similarities.
