Condorcet paradox
Self-contradiction of majority rule / From Wikipedia, the free encyclopedia
This article is about results that can arise in a collective choice among three or more alternatives. For the contention that an individual's vote will probably not affect the outcome, see Paradox of voting.
In social choice theory, a Condorcet paradox (or voting paradox) is a situation where majority rule behaves in a way that is self-contradictory. In such a situation, every possible choice is rejected by the electorate in favor of another, because there is always some other outcome that a majority of voters consider to be better.
