This chapter focuses on familiarity in the courtroom. Specifically, this chapter describes how familiarity between an eyewitness and a defendant affects juror decision-making in terms of perceptions of guilt and credibility of both the eyewitness and the defendant. The chapter describes how familiarity has been operationalized in the juror decision-making literature and discusses various definitions of familiarity, such as exposure duration, number of exposures, and the context of the relationship between the eyewitness and defendant. Research examining how familiarity influences jurors’ judgments is summarized. The chapter also discusses the association between familiarity and eyewitness confidence and its impact on jurors. The chapter concludes by describing familiarity within the context of real court cases, the use of expert testimony, and how familiarity may have affected judges’ rulings.

Research demonstrates that juror race may interact with defendant race to influence decision-making, but little work has investigated interactions with eyewitness race. This study tested whether Black/White jurors would produce different perceptions/decisions when faced with a Black/White defendant identified by a Black/White eyewitness. We also examined the influence of expert testimony regarding the cross-race effect in two floating cells. Mock jurors read a trial transcript, provided a verdict and trial party ratings, and indicated perceived race salience. Black jurors were more likely to convict a White defendant identified by a Black eyewitness than a Black defendant identified by a White eyewitness. Expert testimony was valued more highly when the defendant was Black, but had no direct influence on verdict; however, it raised race salience perceptions (as did presence of Black trial parties). Perceived race salience was associated with lower rates of conviction, suggesting that race and expert testimony have potential courtroom implications.
