我们通过汇编和分析一个数据集，详细描述了全国近1亿次交通拦截，评估了美国警务中的种族差异。我们发现，黑人司机在日落后被拦下的可能性更小，这时一层“黑暗的面纱”掩盖了一个人的种族，这表明在停车决策中存在偏见。此外，通过检查被拦下的司机被搜查的速度和搜查发现违禁品的可能性，我们发现有证据表明，搜查黑人和西班牙裔司机的门槛低于搜查白色司机的门槛。最后，我们发现，娱乐性大麻合法化减少了对白色、黑人和西班牙裔司机的搜查次数，但搜查黑人和西班牙裔司机的门槛仍然低于合法化后的白色司机。我们的研究结果表明，警察拦截和搜查决定遭受持续的种族偏见，并指出政策干预的价值，以减轻这些差异。皮尔森等人编制和分析了一个数据集，详细介绍了近1亿次在美国各地进行的交通拦截，发现警察拦截和搜查决定中对黑人和西班牙裔司机的持续种族偏见的证据。
We assessed racial disparities in policing in the United States by compiling and analysing a dataset detailing nearly 100 million traffic stops conducted across the country. We found that black drivers were less likely to be stopped after sunset, when a 'veil of darkness' masks one's race, suggesting bias in stop decisions. Furthermore, by examining the rate at which stopped drivers were searched and the likelihood that searches turned up contraband, we found evidence that the bar for searching black and Hispanic drivers was lower than that for searching white drivers. Finally, we found that legalization of recreational marijuana reduced the number of searches of white, black and Hispanic drivers-but the bar for searching black and Hispanic drivers was still lower than that for white drivers post-legalization. Our results indicate that police stops and search decisions suffer from persistent racial bias and point to the value of policy interventions to mitigate these disparities.Pierson et al. compiled and analysed a dataset detailing nearly 100 million traffic stops conducted across the United States, finding evidence of persistent racial bias against black and Hispanic drivers in police stops and search decisions.
