The basis of citizens' perceptions of the criminal jury: Procedural fairness, accuracy, and efficiency.

Abstract

Two studies examined citizens' perceptions of the criminal jury and their evaluations of 6- or 12-person juries operating under unanimous or majority decision rules. Study 1 was a telephone survey of 130 adult citizens in which respondents evaluated alternative jury structures in the abstract. In Study 2, students were asked to evaluate jury structures for a hypothetical trial in which they were either the defendant or the victim in a crime with a mild or serious outcome. In both studies, jury size and decision rule were related to ratings of procedural cost, and the severity of the crime moderated procedural evaluations. In Study 1, juries were preferred to judges and the 12-person unanimous jury was preferred over other jury structures when the crime involved was serious. In Study 2, there were no direct effects due to variations in jury structure, but subjects appeared to trade off procedural cost and thoroughness of deliberation as a function of the seriousness of the crime. Procedural fairness emerged as the strongest independent predictor of desirability for jury procedures, and fairness was related to representativeness and accuracy. The role manipulation did not influence subjects' responses. In both studies, respondents were very supportive of the jury as an institution, despite a perception that erroneous jury verdicts do occur.
