Re: [EM] James: Part II, strategy terms

Hi Mike, Replies follow on the subject of strategy terms... Apparently we aren't interested in the same distinctions, that's all. By the way, I often use the word bury or burial, meaning to vote a candidate lower than you would if you voted your preferences and didn't falsify any

Dear Mike, you wrote (27 March 2005): I told Markus that I was going to define majority rule soon. My definition of majority wishes is similar, and I guess that I'd better state that definition now, instead of being vague about what I mean by majority wishes and majority rule. If a

I would just like to point out that median rating is to range voting as Bucklin is to Borda. This was noted back in the days when we first considered Majority Choice Approval (Bucklin based on CR ballots of resolution 3), and were exploring to see if there might be any fruitful generalization

[EM] Manipulation Proofing Approval

2005-03-28 Thread Forest Simmons
Approval's weakness is that it is vulnerable to media manipulation. To counteract this we could look at all of the approval winners under all possible media manipulations, and then choose by random ballot from these. Less ambitious, but feasible and adequate: Choose by random ballot from among

I'd said: If a majority prefer X to Y, that's a majority pairwise preference (MPP). The strength of that MPP is measured by the number of voters who prefer X to Y. You say: Well, obviously that's one way to define the strength of a pairwise defeat. Margins provides another way, and
