Deciding Who Decides Who Dies: Capital Punishment as a Social Choice Problem

Abstract

This article is about decision making by juries in capital cases. A jury is a collection of individuals who may possess differing views about factors relevant to the task before them, but who must, nonetheless, arrive collectively at a decision. As such, the members of the jury face a classic social choice problem. We investigate how this problem is likely to be resolved under various institutional regimes, differentiated by the set of individuals who are allowed to participate and the decision rule controlling their activities. As in our previous paper analyzing decision making by juries, we focus here on an aspect of the process that has been neglected in judicial opinions and academic scholarship: namely to what extent, and how, persistent disagreement among jurors can and will be resolved.
