I have a policy of not replying directly to Ossipoff, there is a history of endless debate that turns over details of "you said," and "I said," endless argument that goes nowhere. Here Warren noted in his post that IEVS did not presently allow equal rankings. He was listing this as a shortcoming of IEVS. Ossipoff apparently turned this into an assumption that there was something defective about equal rankings. Warren is correct. He simply described the status of IEVS, which has not yet been programmed to allow equal rankings in ranked methods. The charge that his results are therefore "meaningless" is, well, silly. Many implementations of ranked methods don't allow equal ranking, in the real world. Yes, as Ossipoff points out, most of us would prefer equal ranking (which actually turns ranked methods into something closer to Range, or at least to Approval). But programming equal ranking is trickier, if you are using issue space analysis to determine votes. At what level of preference do you decide to rank equally? Or what other factors influence the use of equal ranking? It is actually a *lot* more complex. And, yes, it is necessary for Warren's results to have wider application. But they are not at all "meaningless" as they stand. ---- election-methods mailing list - see http://electorama.com/em for list info
