Racial Prejudice and Police Stops: A Systematic Review of the Empirical Literature

A police stop must be based on founded suspicion: an officer's ability to correctly discriminate suspicious behavior. However, police stops can be influenced by negative attitudes toward Black individuals. We conducted a systematic review of empirical articles published from 2014 to 2019 that investigated the relationship between racial prejudice and police stops on PsycInfo using keywords such as "race," "ethnic," "police stop," "traffic stop," and "stop and frisk." Results included 16 studies conducted in the United States, England, Wales, and the Netherlands and showed that Black men were the most frequent targets of police stops; that many individuals who have been stopped by the police reported negative perceptions of the police force; that the Stop, Question, and Frisk strategy used by some U.S. police departments proved to be a type of stop that favors racial selectivity; and that traffic stops were favorable environments for racially biased actions by officers. We conclude that institutional racism in police stops proves to be a problem shared by several countries, including Brazil. We suggest more investigations to characterize institutional racism in the police force and in other settings and interventions aimed at reducing individual biases and collective racist practices.
