Racial disparity in police stops widens when officers can visually ascertain the driver’s race

Evidence

Trying to isolate the influence of race from other factors such as crime, the researchers used daylight saving time as a type of naturalistic experiment (Grogger & Ridgeway, 2006). They found that Black drivers were less likely to be stopped after dusk, when it is dark and presumably harder to ascertain a driver’s race, than at the same time of day during parts of the year when it is still light out and easier to ascertain a driver’s race. — Joseph Avery, Jim Sidanius, Joel Cooper, Gregory Davis, Amanda N., Bias in the Law, 363
