The Arrow Impossibility Theorem states that it is impossible to design a voting system that satisfies a set of reasonable criteria, including: (1) ) Unanimity: If all voters prefer one candidate to another, then that candidate should win. (2) ) Independence of Irrelevant Alternatives: The outcome of an election should not depend on the presence or absence of other candidates. (3) ) Non-Dictatorship: No single voter should be able to determine the outcome of an election.
