Mock juries, real trials:how to solve (some) problems with jury science

Jury science is fraught with difficulty. Since legal and institutional hurdles render it all but impossible to study live criminal jury deliberation, researchers make use of various indirect methods to evaluate jury performance. However, each of these methods is open to methodological criticism and, strikingly, some of the highest-profile jury research programmes in recent years have reached opposing conclusions. Uncertainty about jury performance is an obstacle for legal reform; ongoing debate about the ‘justice gap’ for complainants of sexual offences has rendered these problems acute. This article proposes a way to advance the debate.
