James - Can you elucidate why this should be a required criterion?Date: Sun, 14 Mar 2004 21:22:10 -0800 To: Doreen Dotan <[EMAIL PROTECTED]>, From: "James Green-Armytage" <[EMAIL PROTECTED]>
I may as well point out that there is some controversy on the list about the merits of approval voting. I happen to be a person who is a bit more dubious about it than some. One serious drawback that it seems to have is that it doesn't pass the "majority" or "mutual majority" criterion as defined below:
majority criterion: If a majority of the voters prefers all of the members of a given set of candidates over all candidates outside that set, and they vote sincerely, then the winning candidate should come from that set.
What would be an example of such a case? Would such "unfairness" arise with sincere CR, or is this a consequence of strategy?Both approval voting and cardinal ratings fail this criterion, which makes them strategically problematic as well as generally unfair in some cases.
