A total of 1.5 million people are incarcerated in the United States’ prisons. Tens of thousands are placed in restrictive, solitary confinement units. Building on theories of representative bureaucracy, this article considers both the race of the inmates and the race of correctional staff. The article has three main findings: that minority prison staff have higher preferences for rehabilitation and lower preferences for punishment, that prisons with a high percentage of Black inmates utilize punishment at higher rates, and that representation, in the form of Black staff, helps ameliorate the high level of punishment associated with a high percentage of Black inmates.
