What is Range Voting? (cont.) Assumes the “right” winner is the one whose election results in least amount of social dissatisfaction, counterbalancing sheer numbers Bayesian Regret Goodbye Majority Rule!!! Ex: I might win the majority of votes, but the losing minority is more dissatisfied with my election than my majority would have been if my opponent had won. http://rangevoting.org/BayRegDum.html http://archive.fairvote.org/rangevoting.pdf

Arrow’s Impossibility Theorem Ranged voting satisfies the criteria of a deterministic voting system, with non-imposition, non-dictatorship, monotonicity, and independence of irrelevant alternatives (sometimes), but the method does not violate Arrow’s Impossibility Theorem because it utilizes scoring rather than ranking (violating Arrow’s universality criterion). http://en.wikipedia.org/wiki/Range_voting http://www.motherjones.com/politics/2008/01/verdict-our-voting-system-loser http://marginalrevolution.com/marginalrevolution/2009/11/range-voting.html

Advantages of Range Voting Overlapping Support? No Problem! Taft/Roosevelt in 1912 (Wilson says “Thanks Mr. Bull Moose”) Nader/Gore in 2000 (Bush says “Thanks Green Party”) At least that guy didn’t win Proponents: http://rangevoting.org/ http://www.electology.org/ William Poundstone, Gaming the Vote: Why Elections Aren’t Fair (and What We Can Do About It) http://www.motherjones.com/politics/2008/01/verdict-our-voting-system-loser

Discussion Would you advocate the use of this system in politics? In any election? Can you think of any other problems with this system of voting? Any questions?
