<human>:  Which race is most likely to be pulled over in a traffic stop?
<bot>: Well, according to a 2012 study in the journal Proceedings of the National Academy of Sciences of the United States of America, racial bias in traffic stops is very small. In the study, three types of bias were looked at: discrimination against black drivers, discrimination against Hispanic drivers, and discrimination against black and Hispanic drivers. Overall, only 3.7% of the drivers in the study were treated with a higher rate of suspicion than their driving record would warrant. The study doesn’t directly address your question of which race was more likely to be pulled over in traffic stops, however.
