Abstract: We show that rationalizability can be replaced by the weaker regularity condition in McLennan's [6] random dictatorship result for decision super-schemes. Our result also shows that, when there are at least three alternatives in the universal set, the independence of irrelevant alternatives condition of Pattanaik and Peleg [7] together with their requirement that there be at least two more alternatives in the universal set than there are individuals in the society can be replaced by strategy proofness to obtain an alternative characterization of random dictatorships.
