Abstract
African Americans, compared to Whites, are starkly underrepresented in scientific and technological professions, are especially reluctant to participate as research subjects, and they express attitudes that are skeptical of science and scientific institutions. This article seeks to explain the racial gap in confidence in science (race being socially defined), putting to empirical test explanations suggested by research on human capital, inequality in educational opportunity, and culture. The results show that differential returns to schooling account for about a third of the racial divide, with various cultural mechanisms explaining most of the balance.
