In \\cite{McL11}, McLennan showed that a similar impossibility result holds even if we consider a weaker notion of strategy-proofness where voters believe that the other voters' preferences are i.i.d.~(independent and identically distributed): If an anonymous voting rule (with at least three candidates) is strategy-proof w.r.t.~all i.i.d.~beliefs and is also Pareto efficient, then the voting rule must be a random dictatorship.
