 The problem. While much of epistemic social choice theory seeks to optimize the aggregation rule \(F\) given a fixed group size \(n\), jury theorems are an exception. They fix \(F\) and vary \(n\), addressing how collective epistemic performance—measured by correctness probability or more generally expected decision value—depends on group size. Notorious questions are: does performance increase in group size (growing reliability) or peak at some finite group size? And how well does the collective perform in the limit?
