Children from historically disadvantaged castes face systemic hurdles in education in India—ill-equipped schools, poorly trained teachers, discrimination—leading to high failure and dropout rates. Children from disadvantaged castes also face subtler psychological impediments. One such impediment is consciousness of negative stereotypes. Via an experiment, this study illustrates how caste consciousness could affect academic performance, and finds that children from disadvantaged castes perform poorly in tests when made aware of their caste and reservation status than otherwise. The study underlines the need for reform in how India implements its reservation policy to narrow some of the inter-caste differences in educational attainment.
