Inaccurate beliefs about racial gaps in productivity can have wide-ranging implications in the workplace. In an online experiment, we hired a nationally representative sample of Prolific workers to assess the performance of Amazon Mechanical Turk workers on a math test based on stylized resumes. Participants randomly assigned to a Black primary investigator evaluated Black workers as more productive than participants assigned to a White primary investigator. This study provides suggestive evidence on how the racial identity of supervisors may shift perceived racial differences in productivity and how Black leaders can disrupt belief-based discrimination against Black workers.
Opoku-Agyeman et al. (Fri,) studied this question.
