Can Jury Instructions Have an Impact on Trial Outcomes, California, 2018

This funded project tested whether "implicit bias" jury instructions can mitigate discrimination by juries. Implicit bias instructions are being used in a small but growing number of jurisdictions, but have not yet been adequately tested for efficacy. The study employed a 2 x 2 x 2 factorial design, in which the race of defendant (Black or White), race of informant witness (Black or White), and jury instructions (implicit bias or standard bias instruction) was varied, creating eight experimental conditions. The data in this archive represent 623 participants who were assigned to one of 120 jury groups who viewed a federal drug conspiracy trial, deliberated to a verdict, then completed a series of individual measures.
