Abstract

We generalize the classical binary Condorcet jury model by introducing a richer state and signal space, thereby generating a concern for consistency in the evaluation of aggregate information. We analyze truth-telling incentives in simultaneous pre-vote communication in heterogeneous committees and find that full pooling of information followed by sincere voting is compatible with a positive probability of ex post conflict in the committee.
