For some reason, Chris continues to insist upon the specious distinction between elections and general decision-making process. The term "election" covers any kind of choice being made; however usage focuses on the selection of one candidate out of a number, for single-winner, or of multiple candidates out of a larger number, for mutiple-winner. And we also assume, generally, for the purposes of this list, that elections are of candidates, and the candidates are people who will hold an office. But for a group to select candidates or to select a pizza involves, properly, the same considerations. Pizza is almost certain to be less important a choice, but the importance of the choice only should mean that greater care would be taken. Not that a different process is involved. It's quite easy to imagine a group of people simply voting on the pizza, with the style with the greatest number of votes being the one purchased (the example has been assuming that for some reason, only one kind can be purchased). Yet if such a poll is actually held, and a pizza is chosen that is offensive to a member of the group, that member is quite likely to pipe up with "I can't eat that!" And most groups will alter their decision. Only if they have a *strong preference* for what they chose by plurality will they refuse to consider something else. So, yes, there is a difference between *informal* group process, which the pizza example represented, and the formal process of an election. But non-political group choices can also use formal process. What are the optimum methods for groups to make choices? Single individuals sometimes use Range techniques to make choices. You set up a decision matrix, assign values to the various possible outcomes, and look for the greatest value. Range simply averages this technique over the values assigned by multiple people. The only substantial argument I see against Range is that the method is allegedly vulnerable to strategic voting. *But what we have now is what Range would look like if everyone votes strategically.* So Range would not make things worth, unless... unless honest people vote intermediate values, and dishonest people vote the extremes, and there are enough of these dishonest people that election results are warped as a result. However, I have argued that this can only happen when the honest people do not have a strong preference. When they have, and express, a strong preference, and they are in the majority, the dishonest people can try what they may, they can only nudge the results among candidates strongly preferred by the majority. Essentially, some writers treat the vulnerability of Range to strategic voting as if it were a proven thing. They simply assume it. It has *not* been proven, far from it. And it seems to me that this is a false charge against Range. Electing candidates to public office should not be different in principle than, say, choosing a route for a road, out of a number of possibilities. Strong feelings can be involved, based on the effect this road will have on people who live or work near it. Property values can shift. And an optimum method for choosing pizzas for a group should not be different in principle from what is optimum for choosing candidates for public office. The only difference I can see is that the pizza choice is unlikely to be made using a complex ballot. But if the choice were being made for a million people, indeed such a ballot would properly be used. Chris has asserted multiple times that elections are different from choosing pizzas. He has *never* stated how the differences that exists would affect what election method is optimal. He might as well say that they are different because pizza begins with P and candidate begins with C. >>That is, if the majority does not want to please the minority, it >>does not care if they are devastated by the outcome of the >>election, if their attitude is "they should get over it," then they >>can easily get what they want. Just vote it as a strong preference. >> >The problem with Range is that if "the majority" are not self-aware >and coordinated, they cannot >"easily get what they want". On the contrary, the condition being described was that the majority had a strong preference. Under Range, all they need to do is vote that preference as a strong one. What coordination does this take? This has been stated so many times by Warren, but obviously it bears repeating. The best vote in Range is a sincere one. Sure, partisans may distort their votes, turning them into black and white. But by so doing they are essentially eliminating their own true preference strengths from the election. They are harming themselves, not the society, except to the extent that the society is harmed when individuals are not satisfied. They are risking their own dissatisfaction, if it turns out that, by voting black and white, they effectively abstained from voting in the top two pair-off. So what these Range opponents are proposing is that a substantial group of voters are going to conspire to weaken their own election expression. Certainly it might happen, people act against their own interests all the time. But it's not a stable configuration. The examples that I've seen suggesting that Range somehow encourages strategic voting have been highly artificial ones. It's difficult to model Range in the way that other methods have been modelled, by proposing a few groups who all vote the same way. This *never* happens in real elections.... However, just as with my own project, FA/DP (which would almost certainly use Range Voting where that is appropriate, it simulates the process by which power would be exerted by FA/DP organizations), the proof will be in the pudding, I highly encourage the adoption of Range techniques by various organizations, so that Range experience can accumulate, so that we can see, by looking at actual elections, how the electorate behaves. We should really try to actively gather that data, real ballot information from Range elections. >>But they should remember what happened to the one who said "Let >>them eat cake." >> >>She lost her head.

Only a few were actually killed. Chris, your way of thinking is positively dangerous. Methinks you have a conclusion set in stone and you are seeking, desperately, to find justifications for it an arguments against anything that might threaten it. >>Systems which do not maximize and spread satisfaction lead to >>revolutions or civil war. >Are you talking about election systems or class systems?

The simplest would be a Majority winner. It might be the Plurality winner. Or the Condorcet winner. However, a Condorcet winner who has only a small percentage of the first-preference vote is probably not worth electing, if there is a clear Range winner; likewise a Plurality winner. I'm not sure exactly what winner would best be chosen, it would be worth considering. The Range ballots would be analyzed by converting them to ranked ballots, which is trivial (equal ranking allowed). I'm inclined that it be a Majority winner. Remember, the objection was that somehow choosing the Range winner would be a violation of majority rule. Well, this would guarantee that majority rule would not be violated. The majority could choose the winner, but in a context that made it clear that they were deciding not to allow the Range winner to prevail. (Or they could decline to accept the Range winner, though that is actually unlikely. After all, they gave that winner a reasonable vote, indicating that the candidate was acceptable.) This second vote where it might seem that the majority will was being frustrated, perhaps by an allegedly strategic-voting minority, would be a safety mechanism against such a possibility. It would all be clear, after the Range ballots had been cast and recorded and were available for analysis, what had happened. A conspiracy to bullet-vote would be exposed, for serious insincere voting would stand out like a sore thumb. Uh, you preferred Nader, but you gave Gore a zero and Bush a 50? You and a million like you? If Nader was, because of this, the Range winner (I think it quite unlikely), then, if we presume that the Gore voters outnumber the Nader voters, in that pairwise election, and they truly feel betrayed, they are going to shoot down Nader in the ratification or runoff. Such strategic voting would be more likely to shift an election from Gore to Bush. Smart move, guys. Uh, isn't this what actually happened in 2000? The Green Party took a major hit because this. (Of course, in a plurality system, they had no way of expressing support for their favorite and simultaneously participating in the top-two pairwise election.) In 0-99 Range, with Gore vs Nader vs Bush, they would probably be advised to vote Nader 99, Gore 98, Bush 0. If they were going to vote strategically. Otherwise they just vote sincerely and let the chips fall where they may. But that strategic vote would still express a preference for Nader, would still provide campaign funding for the Green Party (presumably such Range ballots would be analyzed to determine the preference winner for public campaign financing purposes.) (I oppose public campaign financing, it is the wrong approach, but it *does* exist and is going to be a problem in election reform.) Note that who the alternate winner is not relevant to the actual process if the question "Shall the Range winner be elected?" It is conceivable that this question could actually be on the original ballot. This would satisfy, technically, the requirement of majority rule. If it failed, some other method, presumably chosen in advance, would be used. The Range data would then become a universal public poll, quite useful for other purposes.... I prefer a question after the initial election. And I was trying to avoid making it routine, given that so many people seem to think that the expense of a second election (and maybe a third) is significant. The fact is that it would be simple to drastically reduce the expense of elections: use Asset Voting to create, effectively, an Electoral College and use Range Voting in that College. This could convert the election into a deliberative process, and the ratification vote would always be taken. It would take minutes. Majority Rule. What a concept! (Warren, I think you made a tactical error by deciding to push Range rather than Asset. Asset really has the serious revolutionary possibilities.... but it stays closer to existing practice than Delegable Proxy). ---- election-methods mailing list - see http://electorama.com/em for list info
