Abstract Objectives To assess whether data on traffic stop outcomes causally impacts public approval of discretionary traffic stops as a crime control strategy. Methods We distributed an original online survey experiment randomly assigning respondents ( N = 4740) into either the (1) contraband condition, (2) disparity condition, or (3) the control condition. Results In comparison to the control condition, the contraband condition significantly increased respondent support of discretionary traffic stops as a crime-fighting tool. Black respondents assigned the contraband treatment were significantly more likely to support the use of discretionary traffic stops compared to Black respondents assigned the control condition. Conclusions Although scrutiny exists regarding the efficacy of discretionary traffic stops, public opinion may be shifted if they are provided with information on the outcomes of such stops. Police agencies should consider coupling evidence-based strategies with data on the outcomes of crime control strategies, which may also address community desire for more transparency. Minority civilians may support crime control strategies if presented with data on such strategies’ effectiveness.
