This seems pretty fair. There is no specific incentive to obtain the most seats (parties can always form a coalition later).

But you still have the problem that it's open to endless debate, what exactly the realistic simulation method is. Right, Warren's proposal is to try lots of different variations. A method that scores best under lots of different assumptions is likely to be best. Ofc, even then, he may not have covered enough search space. But this ignores the fact that parties still want to try to win the election. If they back candidates at random, they could conceivably hold on to frontrunner positions, but they wouldn't generally win, so they don't do this. One option here is to do what parties actually do and hold a plurality primary. In fact, lots of different primaries election types could be tested. It is still a problem to take this interpretation of FPP as a starting principle to measure *all* rank ballot methods. The advantage is that it can be easily applied to voters with random utility. It automatically splits them into 2 groups. I am not sure I've seen the other thread but I'll look for it. It was the suggestion that you pick 2 candidates as the top 2 and then test if it is stable by allowing each voter to change his vote one at a time. Perhaps... I've never written a simulation to study nomination incentive specifically, but I have written e.g. a FPP simulation, in which voters stop voting for a candidate (in the polls leading up to the election) when the calculated benefit to the vote disappears. And in FPP there is no way for the benefit to come back (in contrast to, say, Approval, which in my simulations of the same sort had the potential to never arrive at stability). If there isn't a condorcet winner, then you get instability. I remember running sims on the Rank your favourite of the top 2 and all you like better strategy and it is unstable, if there isn't a clear condorcet winner. This is a representation of approval's condorcet seeking behaviour. Election-Methods mailing list - see http://electorama.com/em for list info

Re: [EM] Range Voting vs Condorcet (Greg Nisbet)
Dear Diego, you wrote: The risk of minority will remains. How does FAWRB perform in binary issues? What you mean by risk of minority? That a minority favourite may win? Well, that is just the *feature* of FAWRB: It gives each part of the electorate full control over an equal share of the winning probability. This is the requirement of democracy. So, when 55% prefer A and 45% prefer B and both groups do not care to look for a good compromise C or do not cooperate in electing such a good compromise by using FAWRBs cooperation mechanism, then indeed A will win with 55% probability and B will win with 45% probability - which is just fair and what a democratically thinking person would expect. This also answers your question about the binary case. However, let me point out that in most real-world issues, there is a possibility to come up with a good compromise option. Sometimes, for example, this can be achieved by side payments, that is, C is A plus some payments (or other forms of compensation) from the A supporting group to the B supporting group. Once a good compromise is found, using FAWRB makes it probable that this compromise is also elected. Majoritarian methods fail here since with them, the majority has no incentive at all not to bullet vote for A and thus overrule the rest. If a consensus exists between the factions, then this danger would be too rare. There`s no gain for any faction to leave the issue undecided. I don't think so. In my experience of politics it is often the case that one faction strongly wants to stick with the status quo, so they would have a strong incentive to refuse cooperation under your scheme. Not always we can find an unanimity... Yes, that's exactly the reason why sometimes we need to resort to a chance process in order to give every voter their fair right to influence the decision.

This is an illogical question. By definition, single winner elections methods are for electing single winners. By definition PR-STV is for obtaining proportionality of the voters for which several winners must be elected together. So you are not comparing like with like. Fair enough, I meant would you elect a legislature via single winner or PR. Single winner voting systems should, of course, be used only for single-office elections, like city mayor or state governor. Single winner voting methods should never be used to elect assemblies, like a city council or a state legislature. Ok, then we are in agreement. Actually, I would see the reviewing House of the legislature as less important in this regard, but the primary/government linked House should be PR based. There is, of course, a separate debate about the nature of assemblies elected by PR voting systems (of different kinds) and those elected by single-winner voting systems. But that is essentially a political debate about how representative or how distorted you want the assembly to be, and about some of the other effects of some single-winner voting systems, such as the tendency of some single-winner voting systems to manufacturing single-party majorities within the assembly even when no such majority exists among the voters. Some see such distortion of the voters' wishes as highly undesirable, while others see that distortion as highly desirable, indeed, as an essential feature of the political system for good and effective government.

On Thu, Oct 16, 2008 at 7:58 PM, Jobst Heitzig [EMAIL PROTECTED] wrote: The thing is that in such a case, it isn't really a single 'demos'. It is two groups voting as one. Do you mean to say democracy is only for societies which are sufficiently homogeneous? To a certain extent, I would say it works reasonably if one faction is 75% or no faction is more than 1/3. In the first case, the majority should be sufficiently confident in its power that it doesn't have to be oppressive and in the second case, there is a requirement for negotiation. It also works if there is trust/good relations between the factions, no matter the distribution. Where is breaks down is when one group is a majority but not an unassailable one. If one group is 55-60%, then it needs to stay together or it risks losing control. This is made even worse if there is distrust/fear between the two groups. In Nothern Ireland, they have a substantial minority who don't want NI to exist. It also tends to move power to the leadership of the majority and away from their supporters. You can still have compromises. Only if the majority for some reason prefers to elect the compromise than their favourite. But in that it seems the favourite was just not the true favourite of the majority but the compromise was. So, still the minority has no influence on the decision but can only hope that the majority is nice enough to decide for the compromise. I was thinking of PR + negotiations in the legislature. If a party supports policy A in exchange for policy B being killed, and then the other party breaks its word, then that is bad for that party's reputation. This will make it more difficult for it to make deals in the future. In fact, it can be helpful if multiple issues are voted as a single unit. This allows negotiation between factions in order to make up the majority. This common behavious is a pretty artificial construct to overcome the discussed drawbacks of majoritarian rules. This occurs in Ireland with our Programme for Government. After the election, there is a negotiation between the parties to agree on what the policies/priorities for the government until the next election will be. If the coalition doesn't implement what was agreed, then it could find that one of its members leaves and the government falls. This could lead to a new general election or to a different coalition being formed. A faction can make compromises on issues that it doesn't care about in order to get things that it does. This requires there is no solid bloc though. And when both factions care about both issues? Well, they aren't likely to care equally about every issue. In any case, negotiations will start for the Every decision decided by simple majority and negotiations should improve the utility. It is possible that total utility would fall as a result of those negotiations, but that is (hopefully) unlikely. Sounds reasonable, the problem is that a) people don't like random methods b) it will result in certain outlier elements in society getting some power. a) FAWRB is not a random but a very specific and quite sophisticated method. It only uses a certain amount of chance, just as many things in our life do. Chance should not be mixed up with arbitrariness. Used in a rational way, FAWRB will usually elect good compromise options with near certainty, not leading to significant amounts of randomness. I know, but it does have randomness. Btw, could you create a web page that gives a description of the method, since it was still in the discussion stage the last time you posted here. Yes, I agree.

Re: [EM] Range Voting vs Condorcet (Greg Nisbet)
Dear Greg, you wrote: Group membership is difficult to define. With ranked ballots it's simple, but in the majority criterion debate, I argue that a score of 60% represents 60% of a first preference, not the preference between 59% and 61%. Sorry, I don't get your meaning here. However, it seems to me that there is a confusion about the usage of the term majority in the context of our debate. In the majority criterion and related criteria, we usually don't speak of *the* majority, referring to one specific subset of the electorate, but we refer to *a* majority, by which we mean *any* subgroup consisting of more than half of the voters. For example, consider the classical cycle of true preferences, where voter X ranks ABC voter Y ranks BCA voter Z ranks CAB. In this situation, there are three different majorities: {X,Y}, {Y,Z}, and {Z,X}. Of course these groups are not disjoint and it makes no sense to speak of the majority. Rather, the majority criterion only requires that each of these groups, should they decide to do so, can overrule the third voter. That is, X and Y can cooperate in overruling Z and making sure B wins. Likewise (but not at the same time of course), Y and Z could agree to elect C. So, it usually makes no sense to speak of the majority since most often there are lots of majorities - it all depends on which of these groups happens to make the deal to overrule the rest. ... we have not settled the issue of simultaneous majorities. See above for clarification. There is no issue of simultaneous majorities, the criterion simply requires that each subgroup of more than half of the voters has a way of overruling the rest. It does not require that two such subgroups can do so at the same time, which is obviously impossible. I continued: While of course civil rights are very important to make sure that no-one's basic *rights* are violated, they cannot make sure that everybody's *preferences* are have a fair chance of influencing decisions that are made *within* the limits the civil rights pose. to which you replied: Let me explain my point. I set the bar fairly high for tyranny of majority i.e. it must constitute actually oppressing me and not merely annoying or inconveniencing me to be labelled tyranny. I don't care for the label tyranny. My point is that when a majority is able to overrule the rest with certainty, then that's not democratic. You talk about the destruction of democracy. Did I? I don't think so. I don't think there has been any large-scale truly democratic system yet. Only some families and small groups often decide in an approximately democratic way when they make sure that each member of the group makes a decision at some point in time, for example by letting the members decide in turn. That democracy is an all-or-nothing type thing. I am arguing that a good constitution will prevent a majority from acting in such a way that democracy itself is subverted. Not when the constitution allows the majority to decide all issues without having to be concerned about other peoples wishes. If you argue instead that suboptimal results come about, yes I agree with you. My point is not the optimality of results, whatever that may mean. To define and ensure optimality is a large but different task than to ensure the democratic right to influence the decision. For example, some philosophers argued that it would be optimal if some highly intelligent, well-informed and impartial person (the philosopher-king) decided all issues. Though I tend to agree that this might give optimal results, such a system would obviously be not a bit democratic. On the other hand, simply drawing a random ballot to decide is perfectly democratic since it gives each voter exactly the same power regardless of factions. However, that method would not give optimal results at all since compromise options would get no chance at all. What is missing here is an incentive to cooperate. So, whether a method is democratic and whether it leads to optimal results are just two questions which are in large part (but not totally) independent. This is why we developed FAWRB, a method which gives each voters the same power but gives them also strong incentives to cooperate in finding and electing good compromise options. Again, you speak about actively preventing the majority from doing something that violates the rights of minority. Such cannot be prevented by any voting method! Excuse me! Of course it can. I have demonstrated this over and over. With FAWRB, the worst a majority of, say, 55% of the electorate can do to the minority is to bullet-vote for the option considered worst to the other 45%, thus assigning 55% of the winning probability to that option. But this is not violating the minorities rights since at the same time those 45% of the voters can assign the remaining 45% of the winning

I think the problem, or at least a part of it, is that if we (the election-methods members) were to advocate a method, to be effective, it would have to be the same method. Otherwise, we would split the vote, as it were, against the status quo. Therefore, both Condorcet and Range groups would prefer their own method to win. If that's true, then one way of uniting without running into that would be to show how IRV is bad, rather than how Condorcet or Range is better. If there's to be unity (or a truce) in that respect, those examples would focus on the properties where both Range and Condorcet, or for that matter, most methods, are better than IRV, such as in being monotonic, reversal symmetric, etc. An expected response is that these properties don't matter because they happen so rarely. To reply to that, I can think of two strategies. The first would be to count failures in simulations close to how voters would be expected to act, perhaps with a reasoning of we don't know what strategy would be like, but the results would be worse than for honesty, so these provide a lower bound. The second would be to point to real uses, like Australia's two-party domination with IRV, or Abd's argument that TTR states who switched to IRV have results much more consistent with Plurality than what used to be the case.

A strict interpretation of the majority criterion says that the second candidate should win. The spirit of cardinal methods is that the first candidate should win, even though it's possible to make cardinal methods that pass strict Majority. What does this spirit help when the result will still be the 2nd instead of the 1st candidate, because the method is majoritarian despite all cardinal flavour? Again looking at my 55/45-example shows clearly that compromise candidates are not helped by voters' ability to express cardinal preferences but rather by methods which require also majority factions to cooperate with minorities in their own best interest, as is the case with D2MAC and FAWRB. Would you bother to answer me on this? Sorry about that. Because I've been away for some time, I've got a long backlog of posts, and I'm working my way through them. Let's look at your example. 55: A 100 C 80 B 0 45: B 100 C 80 A 0 Range scores are 5500 for A, 4500 for B, and 8000 for C. So C wins. For Condorcet, A wins because he's the CW. So Condorcet is strictly majoritarian here, while Range is not. You may say that, okay, the A voters will know this and so strategize: 55: A 100 C 1 B 0 45: B 100 C 80 A 0 In which case A wins. This, I think, is what Greg means when he says that a majority can exercise its power if it knows that it is, indeed, a majority. As far as I understand, the methods you refer to aim to make this sort of strategy counterproductive. Because Range isn't majoritarian by default, it doesn't elect A in your honest-voters scenario. I would say that from this, it's less majoritarian, because majorities don't always know that they are majorities. However, it's still more majoritarian than your random methods, because in the case that the majority does coordinate, it can push through its wishes. To answer your question: the spirit helps because majorities are not always of one block, or the same. You have shown that it's possible to be less majoritarian than Range, though.

[EM] Voting Theory and Populism
So yeah... let's assume you have some amount of political capital to get this done. You cannot impose loads of reforms at once on people; it doesn't work. If you had to choose only among the options that you think you could get done, which would it be? I support TRS. Minimal minimal effort and better for the people than primaries!

It also has the added advantage that it is also a redistricting reform (or at least makes redistricting less important). CPO-STV (or maybe Schulze-STV) are obvious improvements, but with big costs in complexity. I do think that vote management is a weakness of PR-STV (I wonder if Schulze STV would stop parties bothering to try). Also, the district sizes need to be reasonable (say 5+). In Ireland, there are 3.86 seats per constituency on average, which I think is to low. =Why have constituencies at all? Also, if you could make one change, would you implement IRNR or redistricting reform?

[EM] Making a Bad Thing Worse
The United States uses FPTP, surprise surprise. However how bad would FPTP really be if you remove some of the stupidity? 1) Primaries Especially the presidential primaries. Why Iowa and New Hampshire I ask you? The Republican winner-takes-state primaries are especially bad. The will of the people is distorted. And the winners of primaries get legal protection. 2) Sore loser laws If you lose a primary, you can't even run in some areas. The state will attempt to prevent you from stealing votes away from your party. 3) Really bad ballot access laws. If people can't even run... it doesn't matter what voting method you are using. 4) The Electoral College Someone explain to me how this makes sense. We elect a group of 538 people who will then elect one person. Umm... why elect these people? They aren't doing anything complicated, they are just signing their name and the name of a candidate. Electing Congress makes sense, how else would you handle the loads of legislation that they create every so often? 5) The Senate States aren't represented by their population. This means rural bias etc. How can their opinion be regarded as representing America's? 6) The House Whose bright idea was it to let the states decide how to redistrict themselves? Seriously. 7) Gerrymandering In addition to (6) and gerrymandering at the local level, the state boundaries themselves were gerrymandered. It was mostly due to slavery, but the vestiges of these funky decisions still remain. There are also a ton of low-population states between California and the Mississippi River, whose brilliant idea was that? 8) Two Parties This might be a consequence of FPTP, but seriously. The Libertarian Party, the third largest, is still TINY by comparison to the Democrats and Republicans. It is no wonder we have so many independents in this country. Many people dislike both parties but have no idea what to do. The UK and Canada seem to manage more parties. 9) Elections on Tuesday why not make election day a holiday? or hold it on weekends?

In any case, that requires 100% of the States to agree for it to be changed. OTOH, if you want to be evil, you could strip the Senate of all its power, that would 'only' require 75% of the States. 6) The House Whose bright idea was it to let the states decide how to redistrict themselves? Seriously. The same people who let legislatures redistrict for themselves. In fact, I think that having the States do the redistricting is better than allowing Congress do it. If the States were independently controlled, then there is less of a conflict of interest. However, the 2 party system is entrenched, so the State legislatures aren't independent. 7) Gerrymandering In addition to (6) and gerrymandering at the local level, the state boundaries themselves were gerrymandered. It was mostly due to slavery, but the vestiges of these funky decisions still remain. There are also a ton of low-population states between California and the Mississippi River, whose brilliant idea was that? I think that once off gerrymandering isn't as bad as gerrymandering after the census. It isn't self reinforcing. As time passes, things change. With Congressional boundaries, they are re-adjusted as things change to cancel it out. You can't readjust State boundaries. 8) Two Parties This might be a consequence of FPTP, but seriously. The Libertarian Party, the third largest, is still TINY by comparison to the Democrats and Republicans. It is no wonder we have so many independents in this country. Many people dislike both parties but have no idea what to do. The UK and Canada seem to manage more parties. There is a need for 3rd parties to concentrate their efforts on specific areas. The problem is that the 2 parties use their power to reinforce the 2 party system. Also, each level of government is held by the 2 parties, so it is hard to break it. Anyway, maybe the Libertarians should pick a state and focus all their national effort on getting a Libertarian elected to the House of Representatives in that State. Once they achieve that, they can move on to getting a second one elected from the State. Ofc, their seat would likely be gerrymandered away since their Representative wouldn't be a member of one of the two parties. Maybe the reason that 3rd parties are more viable in the UK and Canada is that there is more independence in setting the boundaries. This means that they can't be gerrymandered out of existence if they manage to get one seat. 9) Elections on Tuesday why not make election day a holiday? or hold it on weekends? I thought they were held over multiple days with 'early voting', or was that changed? Election-Methods mailing list - see http://electorama.com/em for list info

Thanks for bringing this up, it is a perfectly valid criticism. I don't disagree with this point, but it technically isn't in conflict with what I said. First of all I argue two things, I didn't state them initially. 1) Primaries are anti-utilitarian. 2) The Government enforcing any way for parties to operate is bad. It's sort of catch-22 I know. But think of it this way, we allow people to conduct elections based on FPTP. None of us advocated banning private FPTP elections. However, that does not stop us from criticizing their choice of method. The second point I don't agee with because Median Voter would suggest that candidates would be more centrist on average if primaries didn't exist. I like moderates better than Democrats or Republicans and I think they are better for the country... 2) Sore loser laws If you lose a primary, you can't even run in some areas.

In California, you just have to ask, and many county registrars encourage you to ask. You can ask for a single election, or become a permanent absentee voter. Oregon is exclusively vote-by-mail, as is my precinct in California. Since mail-in ballots must be received by election day (postmarks don't count), it's inherently an early-voting system. In California, ballots are mailed out about 30 days before the election, which makes life difficult for candidates. Oregon says 14-18 days, which seems more than adequate.

Then go back to the war between Condorcet and Range. I think the problem, or at least a part of it, is that if we (the election-methods members) were to advocate a method, to be effective, it would have to be the same method. Otherwise, we would split the vote, as it were, against the status quo. Therefore, both Condorcet and Range groups would prefer their own method to win. If that's true, then one way of uniting without running into that would be to show how IRV is bad, rather than how Condorcet or Range is better. If there's to be unity (or a truce) in that respect, those examples would focus on the properties where both Range and Condorcet, or for that matter, most methods, are better than IRV, such as in being monotonic, reversal symmetric, etc. First, IRV will slay us all if we do not attend to it - it is getting USED. Range and Condorcet are among the leaders and ask two different conflicting thought processes and expressions of the voters: Condorcet ranks per better vs worse, but asks not for detailed thought: ABC ranks A as best of these three. Range easily rates A-100 and C-0. Same thought as for Condorcet would rate B between them, but deciding exactly where can be a headache. Each of these has its backers, but we cannot devote full time to this battle while we need to defend our turf against IRV. I suggest concentrating on Condorcet disposing of IRV because both use almost identical rank ballots and usually agree as to winner. They look at different aspects: Condorcet looks only at comparative ranking. When they matter, we ask only whether AB or BA is voted by more voters. IRV cares only what candidate ranks first on a ballot, though it looks at next remaining candidate after discarding first ranked as a loser. Sample partial election: 9 AE 9 BA 18 CA 20 DA A is WELL LIKED HERE and would win in Condorcet. Count one last voter for IRV: A - B and C lose, and D loses to A. B - A, E, and B lose, and C loses to D. C or D - D wins. What Condorcet calls cycles inspire much debate. Optimum handling does deserve thought, but could be directed more as to how to resolve them. Real topic is that comparing rankings can show three or more of the best candidates are close enough to ties to require extra analysis. I claim this is a comparatively good thing - the worst candidates end up outside the cycles and it is, at least, no worse than random choice to award the win to what is seen as the best of them. Having election results in understandable format is valuable for many purposes: Condorcet records all that it cares about for any district, such as precinct, in an N*N array. These arrays can be summed for larger districts such as county or state. Also they can be published, in hopefully understandable form, for all interested. Range has less information to make available. IRV talks of recounting ballots as it steps thru discarding losers - at any rate not as convenient as Condorcet. An expected response is that these properties don't matter because they happen so rarely. To reply to that, I can think of two strategies. The first would be to count failures in simulations close to how voters would be expected to act, perhaps with a reasoning of we don't know what strategy would be like, but the results would be worse than for honesty, so these provide a lower bound. The second would be to point to real uses, like Australia's two-party domination with IRV, or Abd's argument that TTR states who switched to IRV have results much more consistent with Plurality than what used to be the case. Condorcet has no interest in being like Plurality. Its big plus over Plurality is letting voters rank those candidates they want to rank as best, etc., and using this data.
