In criminal sentencing, medium to dark-skinned African Americans are likely to receive sentences 2.6 years longer than those of whites or light-skinned African Americans. When a white victim is involved, those with more "black" features are likely to receive a much more severe punishment. A 2018 National Bureau of Economic Research experiment found that law students, economics students and practicing lawyers who watched 3D Virtual Reality videos of court trials (where the researchers altered the race of the defendants) showed a racial bias against minorities.
