Bias and Accuracy in Jury Selection

Abstract

When forming a jury, attorneys consider how its composition will affect the outcome of the case. I propose a framework in which jurors, who vary in the accuracy of their information as well as preferences against wrongful conviction or acquittal, decide over a case according to a unanimous rule. The defense and prosecution observe the differences among jurors and can make peremptory strikes. I find that that under some conditions litigants may prefer to strike better informed jurors; and that whether more information is preferable depends on the bias of the jurors.
