That is true. Back in Arrow's day, the word spoiler was not used, but Arrow exactly and broadly describes the spoiler condition as one of his fairness criteria. Study this to understand and was easy to find using google on "Arrow's Fairness Criteria" http://www.ctl.ua.edu/math103/Voting/whatdowe.htm#The%20Independence%20of%20Irrelevant%20Alternatives%20Criterion This reminds me of one of the plethora of other deliberately misleading claims of Fairytale Vote, they constantly cite Arrow's theorem as if that is a logical reason to support IRV when IRV fails more of Arrow's Fairness criteria than even plurality voting does because IRV fails the nonmonotoncity criteria in addition to the spoiler criteria described above which both IRV and plurality fail. Fairytale Vote might be able to fool some of the people all the time, but cannot fool all of the people all of the time like it would like to. Fairytale Vote redefines the spoiler condition to be only spoilers (nonwinning candidates whose presence in the election change who would otherwise win) who have small support among voters -- another very clever trick on their part to mislead the public into thinking that IRV is an improvement over plurality, even though it is much much worse and deprives voters of fundamental fairness and voting rights and eviscerates the ability of the public to oversee the integrity and accuracy of election outcomes. -- Kathy Dopp Town of Colonie, NY 12304 phone 518-952-4030 cell 518-505-0220 http://utahcountvotes.org http://electionmathematics.org http://kathydopp.com/serendipity/ Realities Mar Instant Runoff Voting http://electionmathematics.org/ucvAnalysis/US/RCV-IRV/InstantRunoffVotingFlaws.pdf Voters Have Reason to Worry http://utahcountvotes.org/UT/UtahCountVotes-ThadHall-Response.pdf Checking election outcome accuracy --- Post-election audit sampling http://electionmathematics.org/em-audits/US/PEAuditSamplingMethods.pdf ---- Election-Methods mailing list - see http://electorama.com/em for list info
