Missed here is the background. Oligarchical systems arose out of the state of nature because of their superior organization. I was today thinking about the theory behind plurality voting. The faction with the largest number of supporters could raise the largest army (other things being equal) and could overpower the others -- unless they cooperate, forming a larger faction. Democratic decision systems avoid the necessity of fighting to prove strength by assuming strength from numbers and making the necessary accomodations. While we may think of the goal of democracy as being "to be more just," or whatever, it has to work on a power level, that is, if a democratic system attempts to take power from the powerful, it must have, itself, more power, or we end up with conflict that damages all. There is nothing worse than an even match in war, it can leave all sides demolished. It's quite possibly better to lose! (And, obviously, much better not to fight if it can be avoided.) I'm not sure at all what a "just share of power" is. What is the standard? If we have electoral democracy, or direct democracy, everyone has the same power, one vote. This entity that supposedly has oppressive power is not a person, nor is it, generally, a faction. The "majority" is merely a grouping in any decision, the grouping that outnumbers the other. And in pure democratic process, there are only two groups, and no decision is made unless one outnumbers the others. I.e., if the Yes faction outnumbers, the No faction, the motion prevails; otherwise, it fails. (There is actually a bias against the participation of the presiding officer, who cannot generally vote to create a tie, he or she can only vote to break one. Ties in pure process are *not* resolved by tossing a coin! A tie means that the motion fails. A majority has not consented to it.) Giving the "minority" a "share of power" means making decisions contrary to the consent of the majority. But "sharing power" is not a goal of democracy; rather, the common welfare is. The goal is to make wise decisions; a rough standard of wisdom is consensus; but it is considered, sometimes, necessary to make decisions without consensus, so a *minimum* standard is set, and the minimum is obvious: a majority. Below that point, the thinking would go, it is more likely that the proposed action is unwise than that it is wise. Democracy uses, aggregates, the *judgement* of the people. It is not a grant of power; the people have their power, and it is not something given to them by government; rather, government derives its power from the people governed. And government is most effective and efficient and powerful the more it is true that the people consent to it and participate in it voluntarily. Jobst has not thought these matters through, it appears. Good election methods do a good job of choosing, efficiently, from ballot analysis, what the people would choose if blessed with the time and opportunity to discuss and use full deliberative process. While this goal is *impossible*, because deliberative process is intelligent, it *develops* decisions rather than merely discovering them through counting, methods can approach, at least, what would be chosen if people stuck with their immediate opinions. Deliberative process will choose the Condorcet winner but it will also discover Condorcet cycles and could deal with them -- but I've never heard of it happening. However, there is, sometimes, a better winner than the Condorcet winner based on naive preferences. Deliberative process will ordinarily bring this out. I differ with at least one active Range proponent in disliking that a Range winner be imposed on an unwilling majority. But a true Range winner will almost always be accepted by a majority, even when the initial preferences of the majority would have indicated otherwise. And it has nothing to do with "altruism." It is, in fact, in the interest of all, generally, to do this. There is an issue raised with this by a writer here who misunderstands what is being said. He thinks that Range advocates depend on "altruism," a not uncommon assertion. We don't. Indeed, Range functions quite well with maximally self-interested votes, and, contrary to common assertion, Approval-style voting or bullet voting are *not* always the optimal votes. Based on narrow considerations, neglecting the multiple purposes that election serve, some assert that personal expected utility is always maximized by approval style voting. But if one looks closely, a more sincere vote can be just as efficient, and given the other purposes (such as expressing support for a third party in order to shift the position of a major party), can be more efficient. > > If C wins, the B supporters gain 60% utility, that's large.

Let me put it this way: you assert this, but you have done nothing that establishes that the majority does *not* have the right to its preference. It can *take* its preference, generally. Why shouldn't it? Every legislative body in actual existence, with actual sovereignty, gives the majority this power. On what basis do you assert that this is not a right? I agree that it is not an absolute right. "Rights" are conventions established to guide society; I have no "right" not to be eaten by a lion. I have only the power to prevent it, if I do. We grant the majority the right of decision because the alternative is *worse*. Most societies establish boundaries over the power of the majority, preventing it from oppressing minorities without justice. However, the majority can always circumvent these boundaries *if it cares to*. Sometimes majority must be specially defined: we ordinarily speak of relative majorities in elections. However, under common rules, an *absolute* majority has special power. For example, it can amend bylaws without notice. It's worth looking at this. The U.S. Senate, and all deliberative bodies, has cloture rules. Generally, it takes a supermajority to close debate. The argument for this is that it is in the interests of all that minorities fully express their views, are given the maximum opportunity to prevail; cloture rules requiring a supermajority protect the assembly from making premature decisions. However, the majority can change the rules, effectively. It is quite rare for it to do so, simply to win some motion, for it is widely recognized how dangerous it is. But, in fact, if a majority considers it *urgent* that a motion be passed, if it considers that great harm will ensue if we fail to act, to fail to act is to impose a decision contrary to the consent of the majority, a decision to *wait*. So the majority really *can* decide to proceed, in an emergency. It will almost never do this, in any sane society. It will only do it in an emergency. One of the great hazards we faced in recent years was the emergence of a leadership in the Republican Party quite willing to bypass these safeguards, in the U.S. Senate, for narrow and partisan purpose, not actual emergencies. However, it took only a few Senators from both parties willing to cooperate to prevent it to avoid setting the precedent. I'm not sure, however, that this was wise.... for the agreement was, from the Democratic side, to join in the cloture vote if certain conditions were met, and the result has been the continued packing of the federal judiciary.... I want to underline one point made here. The "majority" is not a person or faction in the ordinary sense. We confuse "majority" with "majority party," which often is not a majority at all, but a plurality. And parties are not monolithic. And the majority has tremendous power, if it chooses to exercise it. In California, several Supreme Court justices were recalled. It took only a majority vote. The effect was to shift the power balance on the court in a way more pleasing to the majority. I'm not at all saying that this was good, it wasn't. But the problem was with the political process and the lack of organization to protect those justices -- who had not been abusing their positions -- not with the power of the majority. It properly has that power. > > It is a very good deal for the B voters > >No, they would have to pay for a solution which I think they have a right to! What is the basis for this *right*? Jobst asserts that the A voters do not "lose" anything by getting C, because they, allegedly, have no right to A. But whether or not they lose anything has nothing to do with rights. If they get A, they have a certain value. If they get C, they have less value. That is the meaning of "lose." It is a relative term. The ratings given by Jobst, we were allowed to assume, are "sincere utilities." And part of the condition was that they are commensurable. However, the neutral value was not given. Suppose that the neutral position, for the A voters, is the choice of A. If A is chosen, they lose nothing, they gain nothing. If C is chosen, they lose a certain value, and if B is chosen, they lose five times that amount. This is consistent with "sincere utilities," which Jobst says he does not believe in, though clearly it can have meaning, and, under some conditions, it could even be measured. Whereas the B voters, I could assert, again consistently with their ratings, might have a neutral position also with A. If A is chosen, they neither gain nor lose value. If C is chosen, they gain a certain value; if B is chosen, they gain 5/4 that value. These statements of gain and loss are entirely consistent with the ratings given, they make them rational and sincere. Now, if we assume that the range of values is the same for all voters, and that one of A, B, or C must be chosen, how can you assert that the A voters don't lose anything by the choice of C? Jobst, it's preposterous. You are out on a limb. The sooner you can see it, the less embarrassing it will be.... Now, as describe, A is the choice that leaves everyone in neutral position. Clearly, A is a *just* choice, it harms nobody. (Given the conditions as I've further specified them.) However, the B voters could get a much better outcome. But it would cost the A voters something. What in the world is wrong with them offering to compensate the A voters for their loss? If they offer the A voters more than the A voters will lose by the adoption of C, then it is win-win. Obviously, there would be no motive for them to offer more than the election of C is worth to them.... but they could offer anything below that and be ahead. Consideration of the common welfare would indicate that some transfer would be appropriate, to more evenly distribute the benefit of the gain possible through S.U. maximization, as would happen with sincere Range Votes in a case like this. There is *overall* gain, but it is not evenly distributed. What if the majority is poor and the minority is rich? Would you still think it "just" to take this value from the poor and give it to the rich? > > Jobst regards it as unjust that the majority should be paid by the > > minority to get an outcome he regards as more just. However, he isn't > > looking at the utilities > >No. Why must I repeat over and over again that I don't believe in >measurable utility. I interpret the numbers I gave in the example in >the way I describes several times: as representing preferences over lotteries! This is a common error. An assumption that utilities are not measurable ignores that we may, in studying a situation, *posit* utilities. The utilities then provide an explanation for preferences and an understanding of preference strengths. To really study situations like this, one needs to look at absolute and commensurable utilities, which, again, can be posited. Jobst started with *relative* utilities, normalized, which are of limited use in studying the justice of a situation. Quite simply, as I believe I showed, the justice could radically change depending on the underlying absolute utilities, which can have greatly different meaning than the normalized, relative ones. (when we assumed, here, that the utilities were commensurable, we made no assumption about the neutral position. What we assumed was that summing the utilities would produce meaningful anticipation of the overall value to society. It is *as if* there were cash values associated with the utilities, though that does introduce the possible problem that the same amount of cash may have differing value to different people. When transfers are considered, though, the transfers, if voluntarily accepted, act to equalize value, the transfers make the utilities commensurable. There would be a better way to say this, ... but it's late. > > The actual > > consequences of the election are irrelevant to him. > >What do you think you do here? Where did I say such a thing? The >actual consequences should of course be that the obvious compromise >solution C should be elected without anyone having to "pay" for it! Where does this "should" come from? Is it based on public benefit? What's the basis? Jobst considers C "obvious" because he is making certain unstated assumptions. I'm not making those assumptions. One thing is clear. It would seem equitable to me that the costs and benefits of public cooperation should be equally distributed, to the extent possible. If this is true, then the transfers I suggested would be just. How to determine them is another matter. The most obvious way is by free offer and acceptance. Ideally, with such, we could get a situation where all voters would rationally settle on a single outcome. Consensus. Yet Jobst, apparently, would consider this unjust. Why should anyone have to "pay" for the "obvious compromise"? Well, why should one faction get a large benefit and another one a smaller benefit, if we assume that all the utilities are positive? Why should one faction get a loss while another gets a gain? -- under other assumptions about the absolute utilities consistent with the ratings. *If* we could somehow guarantee that utilities are sincere, we could maximize overall benefit, meaning that, if it were distributed equally, *all* would benefit the most from the maximizing choice. Commonly, it's asserted that Range Voting is great with sincere voters, but, of course, voters won't be sincere, so forgeddaboudit. It's an error for two reasons: one is that Range works quite well with strategic voters, and sincere voters, as long as they vote *intelligently* -- which is also sincere, but not in a naive way -- do just as well or better, no matter how everyone else votes. The other is that something like a Clarke tax could act to simultaneously encourage sincere voting and the distribution of benefit. Here, I suggested a way to do it without changes in law. All it would take is sufficient organization of the people, for both the majority and minority would need to be organized to be able to effectively negotiate the consensus. That, of course, is quite a trick, but I think it can be done. Indeed, I think it *will* be done. It is far too obvious, inertia means that movement is slow, but inexorable. > > But this is a democracy. > >What is the "this" you are referring to?

Again, the resolution of the apparent disagreement comes if we understand "democracy" as a goal or standard, rather than something completely realizable, and that it applies to each decision made by a society. There are *degrees* of democracy, and there is a *minimum* standard for democracy. We have *total* democracy when we have full consensus. And we have minimal democracy when a majority consents to a decision. Below that level it is not democracy at all, it is oligarchy and coercion. > > Contrary to what Jobst might assume, I have a lot of experience > > with consensus communities, both positive and negative. > >I don't assume anything about your experience and have never said >so.

Every functioning democratic body uses it, with rare exceptions. Supermajority rules are used commonly for routine protection of minority positions, but the majority can suspend the rules if they consider it necessary. This is standard practice, its everywhere that people make decisions by discussion and vote. Some special situations use supermajority rules routinely. They have not proven themselves stable over the long term, and I've seen a lot of evidence that, so far, we don't know how to do consensus long term. Interestingly, this whole discussion has brought out a way in which it might be managed. Theoretically, at least, the best decision would, in fact, enjoy consensus from every *rational* voter. But, of course, not all voters are rational nor would I want them to be. > > Point is, when you don't have majority rule, you have decisions being > > made by something *other* than the majority, even if it is only the > > default "decision" to change nothing.

It's practical when you can set up and maintain the conditions. I think I've figured out how to do that. But I do *not* grant consensus the right to coerce the majority.... rather, I *encourage* the majority to seek consensus, because it is efficient and powerful.

Not now. It would take a book. Go out and participate in some deliberative bodies, in organizations where people are friendly and cooperative. It's not all that unusual!

I gave an example of travel distances. Does Jobst mean that travel distances don't exist? What does he mean? I'm starting to think that what he means is "I'm right and I'm not going to acknowledge it." If so, too bad.

It is, after all, intended as a universal medium of exchange. But for another example, volunteer labor could cut a road through a previously impassable area, allowing faster travel for the faction that otherwise would suffer a loss. Such compromise happens all the time in legislation. A bill is not going to pass as-is; some additional provisions are added that ameliorate costs for some faction or improve benefits for another. > > The assumption that Jobst easily makes, that the C option is more > > just, is based on an assumption of commensurability of utilities > >It is not. Please stop attributing thoughts to me which I never expressed. That's correct. I was wrong. Jobst is not basing it on such an assumption. I thought he was because it would make his comments rational. They are not. They assert justice *with no basis at all*. They assert justice for an action that could be taking from the poor and giving to the rich. His assertion that utilities are meaningless is asserting that all these conditions are meaningless, all that matters is the abstraction that, from sincere ratings -- which he essentially says have nothing to do with value but only with -- what? -- he can assert that a certain choice is a clear compromise, and such a compromise, it seems he asserts, is necessarily just. I lose a dollar or gain a dollar. You lose no arm or two arms. I know! We'll compromise! I'll go for no loss or gain, and you lose only one arm. This is what ratings abstracted from actual utilities can imply. Fortunately, with Range Voting, all that a voter is doing is deciding to cast no vote, a full vote, or something in between, for each of the candidates.... S.U. theory tells us that if voters vote sincerely -- which is usually left conveniently undefined -- Range voting optimizes S.U., which is a tautology, if "sincere voting" means voting absolute utilities. With a Clarke tax, it might mean just that. But Range voting works quite well with normalized relative utilities, or similarly exaggerated ones, which *on average* will correspond fairly closely -- usually -- to absolute utilities, for the purpose of aggregation and decision. >(I stopped reading your post here because it was getting too nasty.)
