The Western District of Washington recently developed an educational video to reduce jurors’ implicit biases. Little is known regarding the effectiveness of this proposed remedy to address a range of implicit biases. This study tested whether this educational video reduces pretrial publicity (PTP) bias. A total of 330 undergraduate participants were randomly assigned to read PTP or unrelated articles. An average of 9 days later, they were randomly assigned to watch the educational video prior to viewing a murder trial. Those exposed to PTP were more likely to convict and found the defendant more culpable and less credible. The educational video did not reduce PTP bias. A more tailored debiasing strategy may be needed to overcome the biasing effects of PTP. Differences in legal decisions also emerged depending on whether participants completed the second phase in-person or online, which has implications for future data collection modes.

华盛顿西区最近制作了一个教育视频，以减少陪审员的隐性偏见。关于这一提议的补救措施在解决一系列隐性偏见方面的有效性知之甚少。这项研究测试了该教育视频是否减少了审前宣传 (PTP) 偏见。共有 330 名本科参与者被随机分配阅读 PTP 或无关文章。平均 9 天后，在观看谋杀案审判之前，他们被随机分配观看教育视频。那些暴露于 PTP 的人更有可能被定罪，并认为被告更有罪，更不可信。教育视频并没有减少 PTP 偏见。可能需要更量身定制的去偏策略来克服 PTP 的偏倚效应。
