Date: Wed, 31 May 2000 08:52:37 +1000 (GMT+1000) From: David Catchpole <[EMAIL PROTECTED]> To: Craig Carey <[EMAIL PROTECTED]> Cc: [EMAIL PROTECTED] Subject: Re: Ooh... I think he's riled. Now, look, (I hate it when media interviewees use that cliche), I don't like Approval, but the simple fact is this- Approval is a method that restricts expression of preferences to a single comparison of one group of candidates with another. That being said, if we are to apply principles of voting to the _counting of votes_ without taking account of true utilities / preferences, Pareto efficiency is satisfied. If you were to say that somehow this was confounded by the "hidden preferences" of the voters, you would need to actually state the assumptions that relate the "hidden preferences" to the expressed votes. I know for one thing that if I were an A>B>C>D>E>F>G>H>I voter voting in Approval (as I have- interesting side note- Australian Republican Movement Queensland has(d) what is effectively an Approval system) without information about any other voters I would not be voting ABCDEFGHI, which is simply an expression of disinterest same as a blank paper. I would vote ABCDE. Similarly a Catchy-like I>H>G>F>E>D>C>B>A voter would vote IHGFE. You could then argue the problem that E won even though 99% of the population preferred A. This is a legitimate problem (after all, I devised it) (by the way that's not a serious comment, _OK?!_). The one you provided was not. I made the assumption that an uninformed voter will fill out half or slightly more of the ballot. You didn't make any assumptions as to how the choice of vote occurred.
