    Abstract

    Condorcet's famous jury theorem reaches an optimistic conclusion on the correctness of majority decisions, based on two controversial premises about voters: they should be competent and vote independently, in a technical sense. I carefully analyse these premises and show that: (i) whether a premise is justified depends on the notion of uncertainty or probability employed; (ii) no such notion renders both premises simultaneously justified. Especially the independence assumption should be weakened.
