Majority judgment vs. majority rule
挑战了仅有两名候选人时多数规则的有效性,提出多数判断法,该方法在极化候选人上符合多数规则,能避免Condorcet和Arrow悖论,且抗策略操纵性最强。
The validity of majority rule in an election with but two candidates—and so also of Condorcet consistency—is challenged. Axioms based on evaluating candidates—paralleling those of K. O. May characterizing majority rule for two candidates based on comparing candidates—lead to another method, majority judgment, that is unique in agreeing with the majority rule on pairs of “polarized” candidates. It is a practical method that accommodates any number of candidates, avoids both the Condorcet and Arrow paradoxes, and best resists strategic manipulation.
