Andy's chiastic method is a way of utilizing range ballots that has a much more mild incentive than Range itself to inflate ratings. He locates the method in a class of methods each of which is based on a different increasing function f from the interval [0,1 ] into the same interval: Elect t

The ranked majority criterion is: if one candidate is top-ranked by a majority of voters, that candidate must win. To me, the natural extension of that to rated systems is: if only one candidate is top-rated by any majority of voters, that candidate must win. You are suggesting that we use the ra

Hi Forest, Well, the interesting thing about my own Single Contest method is not that it's an instant runoff between two finalists (i.e. a pairwise comparison). I can't claim to have invented that. The interesting thing is how resistant to ranking strategies it is. The compromise incentive is not

If one of the finalists is chosen by a method that satisfies the majority criterion, then you can skip step one, and the method becomes smoother. Here are some possibilities for the method that satisfies the majority criterion: DSC, Bucklin, and the following range ballot based method: Elect
