The classic Condorcet Jury Theorem comes with demanding assumptions. This chapter shows that similar results can be derived if the assumptions are weakened. First, if the Competence Assumption is weakened by allowing for heterogeneous voter competence, the Asymptotic Result of the jury theorem still obtains (though the Non-asymptotic Result does only under very specific assumptions). Second, the number of alternatives can be more than two for a structurally similar jury theorem, using plurality voting. Third, different decision procedures, such as the Borda count or the Condorcet pairwise criterion, still lead to the Asymptotic Result. While the Borda count and the Condorcet pairwise criterion have a slight epistemic advantage over plurality voting, for large competent groups this difference is negligible.
