[EM] Are rank methods really better than Approval & CR?

2005-06-14 Thread MIKE OSSIPOFF
Judging from what I was saying the other day about strategy for MMPO & wv, maybe it's time to question the value of rank-balloting, when optimal strategy can, and always will in acceptable/unacceptable situations, involve equal ranking (with MMPO) or favorite-burial (with wv). Some criteria

[EM] The Sincere Optimality for Acceptable Candidates Criterion

2005-06-14 Thread MIKE OSSIPOFF
When I described the acceptable/unacceptable strategy of MMPO with AERLO, that suggests that MMPO with AERLO mets something that is, in some ways, stronger than Strong FBC. It has occurred to me that a criterion should be written to describe that advantage, and that's the purpose of this posti

About wv acceptable/unacceptable strategy, I should clarify that it seems to me that unleess you're fairly sure which acceptabale candidate will be the one whom you can help to win, in the event that there is such a candidate, you should equa-rank tahe acceptable candidates in 1st place. I s

[EM] A simpler geographical example showing that mere ordinal info is inadequate

2005-06-14 Thread Simmons, Forest
Jobst recently gave a nice, but rather elaborate geographical example with different winners for different methods. With a more limited objective in mind (showing the inadequacy of mere ordinal information) I present a simpler example: This example is in the form of two related scenarios that

Title: Nanson Sorry, folks, my enthusiasm ran away with me in my earlier message.  If candidate A is the Nanson winner, it is still possible for candidate B to beat A in a pairwise contest, so in this case the average voter ranks B above A.  It is still true, however, that the average voter

Hello Ken, Nice ideas. Correlation seems like a useful tool that could be applied also elsewhere than with Borda. It sure is more natural (and wider) than the normal clone definitions (unfortunately not as simple but of course so are peoples' opinions). Borda has some problems with strategic
