Abstract. We consider a committee, board or jury that faces a binary collective decision under uncertainty. Each member holds some relevant pri-vate information, and all members agree about what decision should be taken in each state of nature, had this been known. However, the state is unknown and members may attach different values to the two types of mistake that may occur. It is well-known that standard voting rules have a plethora of uninfor-mative equilibria, and that informative voting may even be incompatible with equilibrium. We generalize existing results with respect to preference hetero-genity and analyze a randomized majority rule that has a unique equilibrium. We show that this equilibrium is strict, all votes are informative,...
