Responding because you wrote, but with no authority. On May 12, 2012, at 9:04 PM, Michael Ossipoff wrote: Condorcetists: You want to quibble forever about which rank-count is the best. No - we want to move past that. You object that Approval doesn't let you help your 1st and 2nd choices against your last choice, while still helping your 1st choice against your 2nd choice. True that while Approval is much better than Plurality, it keeps this weakness. But the _big_ benefit starts when everyone can support their 1st and 2nd choices at all. We get back to wanting more when offered Approval's offering only best and worst and we are looking at a candidate we cannot stand grouping with best, yet desperately want to vote as being better than worst. Plurality very effectively puts a gag on everyone who would like something better than the corrupt sleazes that your tv offers as "the two choices". "We have to hold our nose and vote for the lesser-evil [Democrat], so that we don't waste our vote." Again, we do not want this lesser-evil to be seen in the counting as desired equally with best, yet also see this lesser-evil as better than those we classify as worst. Do you have any idea how things would be if everyone could actually support their favorites, and without having to try to guess on which one the other similar voters would be combining their support?

Do want the improvement we see Condorcet offering, and see you seeming to be promoting endless debate rather than working to move ahead. With Condorcet: . Those who still see Approval as good enough can vote it in Condorcet by using a single rank for all liked candidates. .. Those who want to indicate unequal liking simply use unequal ranking. .. The vote counters can see and respond to the unequal liking. And, as for helping 1st choice over 2nd choice, while helping both over last choice, free of strategy need: You're in deinal about Gibbard-Satterthwaite. You're in denial about Condorcet's blatant and full-magnitude co- operation/defection problem. The problem can be overstated.

I guess we are speaking about the U.S. elections here.

I note that that would lead to an interesting political system that has probably not been tested anywhere in the world yet. > > Do you understand the difference between "liked" and "unliked"?

Do you recommend "sincere Approval" where people sincerely approve those candidates that they "like", or "strategic Approval" where people are supposed to find the best strategy for them and vote that way? (The best strategy often includes approving the "lesser-evil" too.) My guess is that in public elections strategic approach to Approval would dominate. > > Do you have any idea how far-reaching the resulting changes would be? > > No, I'm not saying that the resulting country and world would be perfect in > every way.

If this is a reference to the minor change in the electoral system to change Plurality to Approval, then I agree that Approval has this benefit of being an easy change. I'm not sure that I'd recommend Approval in the U.S. for presidential elections or various representative bodies. But at least for pure single-winner (currently Plurality based) elections like maybe mayoral elections Approval could be a step forward. That leaves open the posibility of moving later forwad for example to Condorcet methods. > > And, as for helping 1st choice over 2nd choice, while helping both over last > choice, free of strategy need: > > You're in deinal about Gibbard-Satterthwaite. > > You're in denial about Condorcet's blatant and full-magnitude > co-operation/defection problem. I don't see any denial of Gibbard-Satterthwaite or other problems. My understanding is that many people like Condorcet methods because they think that their co-operation/defection problems are relatively small (although they exist at least in theory). To me the promise of Condorcet methods is in that in large real life electons their vulnerabilities would be small and difficult to use, and as a result people could vote sincerely (without strategic concerns and without strategic intent). > > And you're in denial about millions of voters' need to litterally maximally > help the Democrat beat the Republican.

Re: [EM] To Condorcetists:
Juho: You said: I'm a "condorcetist" in the sense that I think that Condorcet methods are a pretty good local optimum for some election types. [endquote] Condorcet-Criterion methods would be fine for EM. I doubt very much that EM members would have any favorite-burial need, with Condorcet, or Condorcet-Criterion methods. However, the co-operation/defection problem can appear just as easily here on EM as anywhere. Therefore, for EM voting, Smith-Top would be fine, in this non-favorite-burying electorate that includes a fair number of people who insist on Condorcet's Criterion (CC). Ideally, I'd still prefer ITC, but Smith-Top would be fine. In fact, for that EM electorate, with so few voters, there could even be an argument for Schwartz-Top. Myself, if EM were voting on political candidates, or on voting systems, I'd consider it a u/a election. Therefore, on the Voter's Choice 2 ballot, I'd designate "Direct", meaning that my ballot would award points directly ,according to my marks on my Approval ballot. ...And, for EM, I'd prefer Voter's Choice 2 to the single-designation Voter's Choice. Maybe Voter's Choice (only allowing one method designation) could have appeal for when the public distrust all alternative methods. Then, single-designation Voter's Choice might be an easier proposal. But even single-designation Voter's Choice should allow the "Direct" designation. If the person wants to use it, it would mean giving one point to one candidate, instead of being counted toward the points that a method could bestow on its winner. If we were using single-designation Voter's Choice in a poll on voting systems, I'd designate "Direct", and give my point to Approval, as the only acceptable in a u/a election. But if that single-designation Voter's Choice poll were about political candidates, and I wanted to help several, then I'd probably designate Approval, ICT, Smith-Top or Schwartz-Top--whichever seemed more popular. Not that I'd necessarily want to help several. So, yes, Condorcet Criterion methods could have use in some electorates, such as EM. Maybe some organizations too. I'd said: > You want to quibble forever about which rank-count is the best. You replied: No interest to quibble. [endquote] Thank you. But of course that's what EM is all about.

I guess we are speaking about the U.S. elections here. Do you recommend compromise seeking single-winner election methods like Approval or Condorcet to be used in electing representative bodies from single-winner districts? [endquote] Juho, I recommend that you look up, somewhere, what sort of elections we do here. I'll explain it. Other than some municipal elections all of our elections are single-winner elections. We elect our state legislatures in single-winner elections (though there have been just a few exceptions). We elect the U.S. Senate and House of Representatives in single-winner elections. I'm not suggesting a complete change of the political system, such as proportional representation or parliamentary government. Parliamentary govt is fine, but it's too big A change to ask for here, at least now. PR is likewise much too difficult to ask for here, a big change. I'm asking only for the minimal change: For our single-winner elections, for which we already use Plurality, I merely suggest that we repeal Plurality's ridiculous forced falsification requirement. And yes, our Presidential elections are effectively by Plurality, at least in the states, for the most part. Many would prefer one nationally-counted presidential election. So would I, but I'd settle for Approval in the states, first. But, first of all, Approval for Congress (HR and sentate), and state legislatures.

And widely used, Juho! I > kid you not! Yes, I know. I was thinking that good single-winner methods have been designed to elect single winners. They are not designed to elect representative bodies from single-winner districts. In theory use of a Condorcet method in the Senate and House of Representatives elections could lead to electing all representatives from a small centrist party (zero from Democrats, zero from Republicans). Probably that is not the intent. I see multi-winner methods as a separate set of methods where the requitements are quite different from the single-winner method requirements. Representative bodies have multiple members, so by default they should use multi-winner methods. Pluraity based two-party systems are a special case that uses Plurality (a s-w method) to achieve the two-party effect in a m-w election. But in general, a good s-w method is not necessarily a good m-w method, and a good m-w method is not necessarily good s-w method. I do understand that jumping e.g. to PR and multi-winner districts in the U.S. may not be possible in the short run. But I have not heard anyone naming use of single-winner methods in single-winner districts to elect multi-member representative bodies as their ideal target. Maybe that could be one intermediate step (first easy step) on a path towards something else. When I say that Condorcet methods are good methods I mean that they are good methods for typical single-winner elections (or to be more exact, for _compromise_seeking_ single-winner elections) (and I don't mean single-winner districts in multi-winner elections). > What would be somewhat new would be single-winner elections without > Plurality's forced falsification requirement. And yes, the lack of testing > and prior experience would be a problem for most reform proposals. But not > for Approval, because, as I said, that minimal change from Plurality is so > simple that it would be obvious that it would be an improvement, and nothing > other than an improvement. Both Approval and Condorcet methods are compromise seeking single-winner methods in the sense that they tend to elect centrist compromise candiates with no requirement of proportionality. In that sense changing the method from Plurality to Approval may lead to major changes in the distribution of the seats in the long run (although the technical change is small). If one starts from a two-party set-up, in the first elections Approval may just allow some approvals to be given also to third parties, but it may still elect practically all representatives from the two old parties. Old party supporters might generally bullet vote. But in the long run things may change. Approval has the tendency to elect centrists, not from the two major parties of the two wings. One may consider also that property to be an improvement. But from another viewpoint, maybe people don't want the system to change in that way. If one wants to allow also third party candidates to win, maybe the long term t arget could be proportional representation of all the parties. The problems of Condorcet (when used as part of a a multi-winner method in single-winner districts) are quite similar. It is possible that use of Approval would not lead to as clear tendency of electing centrist candidates as described above. But that does not mean that the method would behave in some other sensible way that would be easy to predict and easy to justify. Large parties might continue to bullet vote, and small parties might not grow strong enough to widely challenge the old strong ones. Voters might stick to the stong ones since they are considered to be the strongest players in Washington anyway. > If you're merely saying that you make no recommendation regarding voting > systems here, then that's fine. If you're saying that Approval is less > qualified for > recommendation, than that claim would call for justification. I think the U.S. citizens should decide, and I try to avoid taking position on what they should do. However, the reason why I see potential problems in the use of Approval or Condorcet in electing representative bodies is that they are not planned to be used that way. There is no nice theory behind that would support that kind of a political system. But maybe also such untested political system could be one useful (intermediate?) step in the reform process. U.S. citizens to decide. For presidential elections Approval and Condorcet would be fine (or as good as they are as single-winner methods) except that the presidential elections of the U.S.A. are not pure single-winner elections in the sense that the whole presidential system is based on the assum

I've told how > the problem would come about, in Condorcet, just as well as in Approval. > Condorcet is not strategy-free, or anything close to it. Since you had some concrete examples I'll provide some concrete feedback in line with what I asked you to provide. Sincere opinions: 33: A>B 32: B>A 34: C In the U.S. these must be A = Republicans (that hate C as you told) B = Democrats C = Socialists Proposed strategic votes: 33: R>D 32: D 34: S You seem to assume winning votes since you expect D to win. So, let's continue with winning votes based Condorcet methods. First problem with the startegy is that it is unlikely that all Democats will vote strategically. If they vote 31:D, 1:D>R, R will win. Reaching 32:D is not probable. Republicans have no reason to worry. Second problem. If Democrats really want to win, they could focus on making D look better than R. If that leads to one voter (= 1/99 of the voters) changing their opinion from R>D to D>R, D will win. On the other had, if they give a public recommendation to their supporters to vote strategically and try to cheat the victory from R, some voters that are close to the D/R border line might get upset and change their opinion from D>R to R>D. If that happens, the Deomcrat strategy will not work even if 100% of their voters will implement the strategy as told. In this set-up it seems that it would be a better strategy for Democrats to simply continue marketing their own candidate instead of starting to market strategic voting. Third problem. If Republicans hate the third (large) party much more than Democrats do it is not probable that all third party voters will truncate. In real life votes are more heterogeneous. If two of the Socialist supporters vote S>D instead of S, D will win even without the strategy. I'd expect more than 0 Socialist supporters to have sincere preference S>D. If this is true, then Democrats don't even need a strategy. Or is there some other real life set-up where these sincere opinions would be plausible? Since Democrats want all their supporters to vote strategically, I guess the strategy would include a public recommendation from the party to all their supporters to truncate / bullet vote and not to express their full preferences. Individual decisions and media guidance probably is not sufficient. Different political cultures may react in different ways to such messages. In some societies people would despise such attempt to falsify the results. In some other societies people might expect the party to reveal all such dirty tricks that they could use to fight and win by whatever means. Based on this quick analysis, and in the absense of other more convicing arguments on how this strategy might actually work in real life elections, I tend to classify this method in the "theoretical vulnerabilities" category (not in th e"practical vulnerabilities" category). I mean that this example is a bit like a Turing machine that demonstrates that something is possible in theory, but doesn't say much about how well and efficiently this strategy (or program of a Turing machine) works in some real life environment. Am I correct? Can you make this type of vulnerability more plausible by changing the numbers, votes or explanation/mapping to some real life society?

Admittedly, the chance of having reason to regret not voting Dem alone at top is quite small. S/he doesn't care. Hir need to _literally_ maximally help Dem beat Repub is genuinely felt, and no one can find something objectively wrong with it. In fact, what would _you_ do under the following circumstances: It's a u/a election. Favorite and Compromise are the only acceptables. Most likely, Compromise is surely or almost surely only candidate who can beat Worse, an unacceptable. What are you going to do, in Condorcet? Hah! You'll vote Compromise alone in 1st place, just as I would. Yes, I've said that I wouldn't favorite-bury in Condorcet. Ok, I was mistaken. Of course we might not know for sure that the conditions are right for requiring favorite-burial. If it isn't certain which acceptable can win, then it can be best to vote them all at top. It depends on what information you have. No one said that Condorcet voting is simple. Or at least _I_ didn't. The voter has to _dither_ about whether, in that u/a Condorcet election, it's optimal to vote Compromise alone in 1st place, or to vote all of the acceptables together in 1st place. There are rough ways to try to guess which kind of situation it is. But knowing for sure? Not a problem in Approval. Just approve (only) all of the acceptables.

I've pointed out that Approval won the most recent EM poll on voting systems. Approval won by every method that we counted. Approval was the CW, the Approval winner, and the Range winner. In the published Declaration-signers list, Approval has more mention than does Condorcet, even if you count VoteFair as Condorcet. In fact, one of the mentions of Condorcet specifically ranks it below Approval. Mike Ossipoff Election-Methods mailing list - see http://electorama.com/em for list info

More specifically, it looks rather bad when you, on the one hand, say that C/D resistance is not incompatible with the Condorcet criterion, then turn around and claim that "Condorcet has a blatant and full-magnitude co-operation/defection problem" of which Condorcetists are supposedly in denial. [endquote] I was referring to the Condorcet versions that are usually proposed. Of course I don't deny that CC and defection resistance are compatible, as in Smith-Top and Schwartz-Top. You continued: Before you talk about a *need* to literally maximally help the Democrat beat the Republican, consider what you have said yourself, in response to my posts. You have said that the voters' overcompromise is a result of their history with Plurality, not an objective *need* to, within Condorcet, rearrange the preferences or the worse guy will win. [endquote] They do so because of Plurality history, yes. But their need to overcompromise is the result of a subjective choice, not an objective error. In fact, under certain circumstances you, too, would favorite-bury in Condorcet. I certainly would. (contrary to what I've said in the past, I admit) Suppose that it's a u/a election. The method is Condorcet. It's pretty much certain that Compromise, an acceptable, but not your favorite, is the only candidate who can beat Worse, an unacceptable. What do you do? You rank Compromise alone at top, that's what you do. As would I. But, maybe you _don't_ know that Compromise is the only acceptable who can beat Worse. Maybe you have no idea which one can beat Worse. Then what do you do? You top rate all the acceptables. The problem, of course, is in the majority of circumstances, when it's somewhere in between those two circumstances. So, then how do you know which to do? Good question. You _dither_. In Approval it's simple and easy: Just approve all of the acceptables and none of the unacceptable. How hard is that? Condorcet is much worse, as described above. You continued: And finally, I'd give this hint: the moment it feels like the "other side" has somehow acquired a preponderance of people in denial, take a more Copernican view. When an otherwise sensible group holds a view that seems to be silly, and to explain the silliness, a greater part of that group needs to be extraordinarily blind (and very specifically so), perhaps they are not. Perhaps, instead, the view is not so silly. [endquote] It's hardly rare for a majority to be mistaken. It's common. You rely too much on polling. As I said, the configuration of advocacy on EM is but a snapshot of something that's constantly changing. As I've mentioned, Approval won the most recent EM poll on voting systems. Approval won by every method that we used. Approval was the CW, the Approval winner, and the Range winner. In the short list of Declaration signers, more people mention Approval than Condorcet, even if you count VoteFair as Condorcet. And one of the people who mentions Condorcet ranks it below Approval.

Juho: You wrote: Yes, I know. I was thinking that good single-winner methods have been designed to elect single winners. They are not designed to elect representative bodies from single-winner districts. [endquote] I don't know when or where Plurality was first proposed &/or used, but I can assure you that it's widely believed here that single-member districts, elected by a single-winner method, is the right way to elect Congress. We agree that PR hasn't any chance in the U.S. And you're right: Approval, or any other good single-winner method would tend to elect the same party to Congress in each single winner district. That's fine with me, because if it's a good single-winner method, then it would be a good choice. As for PR, not only is it entirely un-enactable in the U.S. (in spite of previous use of STV), but it also is obsolete. Don't get me wrong--I'm not criticizing PR. The countries where you and Kristofer live don't have the voting system problem that we have, because PR is used. PR can do a great job. But PR can fail when it has too few seats per district, or a threshold that excludes small parties. PR is fine, provided that there are sufficiently many seats per district, and there isn't an inclusion threshold. I suppose a very low threshold would be ok, but it would be better to have no threshold at all. I feel that any lack of perfection in the results of PR in Europe can be attributed to small districts &/or theresholds. I won't deny that the we could definitely benefit from borrowing some ideas from Europe. Good PR would be one such beneficial borrowing. But, as I said, PR is un-enactable here. I'd be entirely satisfied if a good single-winner method were used for electing Congress and state legislatures in single-member districts. But which would be the _best_? Neither, of course. Proxy Direct Democracy would be best. Proxy DD uses single-winner methods to make multi-alternative choices. I've defined Proxy DD some months ago, and we discussed it. Basically, all decisions now made by Congress are made by direct democracy. Implemented by home computers, library computers, home telephones, etc. I described how an anonymous voter ID number could be obtained and used. A voter can designate proxies, or a sequence of proxies, or indicate that he'll let his voting power follow his proxy's list of proxies. Your proxy could by anyone. Parent, spouse, child, employer, teacher, party leader, candidate, etc. Anyone. You continued: In theory use of a Condorcet method in the Senate and House of Representatives elections could lead to electing all representatives from a small centrist party (zero from Democrats, zero from Republicans). Probably that is not the intent. [endquote] Electing each representative from the same winning party is what happens now, regardless of what the single-winner method is. Of course that was the intent. And, regarding that "small centrist party": There's no reason why a voter-median party must be small. It could be small, or large. And let's be clear about "centrist". It can mean, "somewhere between the Democrat and the Republican". Or it can mean voter-median. Two very different things. You said: I see multi-winner methods as a separate set of methods where the requitements are quite different from the single-winner method requirements. Representative bodies have multiple members, so by default they should use multi-winner methods. Pluraity based two-party systems are a special case that uses Plurality (a s-w method) to achieve the two-party effect in a m-w election. But in general, a good s-w method is not necessarily a good m-w method, and a good m-w method is not necessarily good s-w method. [endquote] As I said, I'd have no objection to PR, provided that there are lots of seats per district, and no inclusion threshold. And as I also said, we could benefit greatly by borrowing ideas from Europe, and PR would be fine. But PR isn't _necessary_ if we use a good single-winner method. PR isn't the only way. I do understand that jumping e.g. to PR and multi-winner districts in the U.S. may not be possible in the short run. But I have not heard anyone naming use of single-winner methods in single-winner districts to elect multi-member representative bodies as their ideal target. [endquote] It would be a fine endpoint target. I'd be fine with a good single-winner method electing Congress in single-member districts. But, for me, the ideal target would be Proxy DD. As I said, it uses a single-winner method for all decisionmaking. You said: When I say that Condorcet methods are good methods I mean that they are good methods for typical single-winner elections (or to be more exact, for _compromise_seeking_ single-winner elections) (and I don't mean single-winner districts in multi-winner elections).

That is of course against the principles of proportional representation. But why not. Many political systems of today try to exclude extremist parties from the system (e.g. using thresholds) and allow only mainstream parties to be represented (e.g. two). Decisions should generally not be extreme. But representation might include or not include all (also extremists). > You said: > > But that does not mean that the method would behave in some other sensible > way that would be easy to predict and easy to justify. > > [endquote] > > If you're referring to Approval, then in what way would it behave > unsensibly, unjusitifably or unpredictably?

Approval and other compromise seeking single winner methods do not respect proportional representation nor the alternating two-party principles. I can't tell how e.g. the U.S. would react to the proposed changes in the elections. Your "village elder" approach where there is no need to have party affiliations could maybe work(?)

Receiving the most "Approved" ratings? :-) In Condorcet a small party that Democrats condider better than Republicans, and Republicans consider better than Democrats, could win.

A mixed-member system. I never felt that districts were very important in PR, but I must admit that I've never lived where there is PR, district or otherwise. It seems to me that I read that Holland doesn't use districts in their PR system, but that might just be because the area isn't large enough to need them. I liked Finland's elegant open list system when I read about it. But didn't I read that you use d'Hondt? That under-represents small parties. Sainte-Lague is more perfectly proportional and more fair. I could be wrong about which proportional formula Finland uses. It was a long time ago when I read about that. Maybe Finland uses Sainte-Lague. > I feel that any lack of perfection in the results of PR in Europe can > be attributed to small districts &/or theresholds. I guess all countries have somewhat different systems and thereby also somewhat different problems. The ones you mentioned are probably common. [endquote] The trouble with party-list PR with small districts or high threshold is that there's a serious split-vote problem. STV avoids it, but at a cost in proportional accuracy: STV and Largest-Remainder list PR share the same kind of suboptimally-accurate proportionality formula. Sainte-Lague is the genuinely proportional PR--provided that districts are small, and there isn't a high threshold (best to have no artificial threshold). As you said small districts are ok if there's a "mixed-member system" in which national proportional results are used to top-up the parties' district seat totals. Anyway, PR is unfeasible for the U.S. And anyway, as I said, I don't want parties that aren't good enough to win in single-winner elections to have Congressional seats. Any PR would be better than Plurality single-winner elections. But we'd be fine with just doing our single-winner elections by a better method, such as Approval. For Congress in single-member districts, as well as for the presidency. > Electing each representative from the same winning party is what > happens now, regardless of what the single-winner method is. Of course > that was the intent. I guess the idea is that the two dominat parties alternate in power. [endquote] That most definitely is the idea here. But we'll see what's dominant when everyone can really express what they really want. But yes, single-member districts will give Congress to only the dominant party or parties. But don't think that that will mean Republocrats. As I said, Republocrats can't win without the Plurality voting system. Remember that, with a good voting system "dominant parties" will mean "best liked and most wanted parties". You said: This way we can get (two-party) proportionality in time. And the dividing line between the two parties is supposed to represent the opinion of the median voter. [endquote] If you're talking about Congressional single-member districts elected by Approval, then I trust that you aren't referring to the Democrat and Republican parties. I don't know how proportional it would be, but that wouldn't be the goal. Electing the most wanted, the best liked, would be the goal of single-member district Approval in Congress. Yes, with Approval, the system would find and stay at the voter median. You said: Use of other methods than Plurality in the single-winner districts may break these properties. That may be good or/and bad. [endquote] How could using Approval instead of Plurality in our single-member districts be bad?

A two-party system is another approach. [endquote] It doesn't matter how many parties. Remember that the "two party system" is an artificat of Plurality. In Approval single-member districts, there would likely still be two or three parties often winning. Or maybe, as people find out things, or conditions change, different parties will be the main dominant one. But the important thing is that, if two parties are usually winning, under Approval, it's only because people genuinely like them best. I don't care how many parties are winning in those single-member districts, whether 1, 2, 3 or 4. It will be whatever the public like. You said: Proxy Direct Democracy could introduce anothe

Yes, Finland uses D'Hondt (and D'Hondt favours large parties when allocating the last fractional seats). Finland also allocates seats independently in each district. That actually favours large parties more than D'Hondt does. As you know having district size of 1 is quite radical from this point of view. In Finland district sizes are from 6 to 34, but still they they favour large parties. There was a reform proposal that would have counted the proportions at national level, but current government decided not to drive that proposal (that was already once approved earlier) forward. > As you said > small districts are ok if there's a "mixed-member system" in which national > proportional results are used to top-up the parties' district seat totals. You can do that also without a mixed-member system. The Finnish reform proposal first counted the proportions at national level and then forced all the districts to make their seat allocations so that the end result was in line with the agreed proportions. > And anyway, as I said, I don't want > parties that aren't good enough to win in single-winner elections to have > Congressional seats. Ok. But note that this approach allows minor parties whose supporters live in few hot spots to get seats, while parties of the same size but with even distribution of voters will not get any seats. > How could using Approval instead of Plurality in our single-member districts > be bad? I've talked about how Approval's results would differ from those of > Plurality. Proportional representation and two-party systems are two well known approaches.

I have now understood that your ideal (or actually best reachable) target system is a system that elects from few large parties, where few > 2. Technically multi-winner elections would use single-winner districts and Approval. Also the president could be elected with Approval. At some point I thought that you might aim at electing good individuals without strong party affiliations, but maybe you are more party oriented that that. I assume that you expect most candidates to have a strong party affiliation. One topic that may need further discussion is the dynamic behaviour of the proposed method. You seemd to assume that the method would converge towards electing candidates from few well known major parties. Could be but I'm not sure. People could also bullet vote (especially the old party supporters), and the old parties could still dominate (although less than before). There would be no alternating power balance anymore, which could mean that people could feel that they can not change the policy however they vote. Would the governments be minority governments or coalition governments? I mean that there could be need for further reforms. The problems of Approval with three or more potential winners might irritate people and change their voting behaviour. I'm not sure what would happen, but I expect this system to be at least in the beginning less predictable than the old well tested approaches. I'm not saying that this system should not be tried. I'm just saying that you might get surprises too, and that the reform process might continue (or return back as in Burlington). > you haven't talked with American > favorite-buriers, and observed their voting, as I have. I didn't observe any strong burial tendency in Burlington when I analyzed those votes. Normal voters do not know what FBC means, so I'd expect some burying to be present in Burlington if people have strong tendency to do so. My guess is that ranked votes of Condorcet elections would no be radically different. Maybe some activists would mention the theoretical strategic opportunities, but still I believe most voters would just rank as they would rank in IRV. Bullet voting is probably a more common deviation from sincere ranking than burial is. > the C/D examples that I've given--my > versions of the Approval b

And if everyone's strategizing, Approval will elect the candidate who is better than expectation for the most voters. I say all this for completeness.

In particular, you have never answered my question about what problem Approval will have that Plurality doesn't have. Will people's voting behavior change with Approval? Most definitely. As I've said many time, those who feel a need to compromise on a lesser-evil will be able to vote for their favorites too.

Because they're the result of voters having more freedom regarding the marks that they give, the 1 point ratings and the 0 point ratings. The freedom to give 1 point to every candidate whom they like. No, you won't like that. But people who live here will like the results. You said: , and that the reform process might continue [endquote] Of course it might. As I've said many times now, there mere fact of the Approval balloting results will show that things aren't as our televisions have been telling us. Public wishes, the genuine mainstream and middle, those aren't what we were told. Rapidly media will be more open, and the climate will be good for additional reforms of various kinds. Those wanting additional electoral reforms will be in a better position than now to ask for them. Rank balloting advocates will try their proposals. Maybe a good one will win. Discussion will be open, and so I think it's likely that anything that wins will be good. You said: (or return back as in Burlington).

Just the usual and thorougly discussed strategy problems of the Approval method. I don't think you discussed them yet. They are however quite independent from the implications of using a compromise seeking single-winner methods instead of Plurality in a two-party political system. Therefore the problems of the Approval method could be discussed separately as a separate stand-alone topic if needed (but there is no need since I assume you are already familiar with those discussions). > > Because I've already answered lots of claims about problems, you need to > say, specifically, what problems you mean, and how you answer my rebuttals > to the claims about those problems.

[endquote] They do so because of Plurality history, yes. But their need to overcompromise is the result of a subjective choice, not an objective error. In fact, under certain circumstances you, too, would favorite-bury in Condorcet. I certainly would. (contrary to what I've said in the past, I admit) Suppose that it's a u/a election. The method is Condorcet. It's pretty much certain that Compromise, an acceptable, but not your favorite, is the only candidate who can beat Worse, an unacceptable. What do you do? You rank Compromise alone at top, that's what you do. As would I. In an Nader-Bush-Gore type of u/a, I would say like this: - Okay, this is an election in the inception of a transition of the method. Therefore, it is u/a. If this had been some time after the people had got used to the new method, it would no longer be u/a. - Therefore, there will be a few "frontrunners", perhaps two or three. These are the ones that will end up in the Smith set in the worst case - certainly none of the minor parties will. - Since I can't push someone off the Smith set by ranking someone not in the set above him, and Favorite isn't one of the frontrunners, I'm free to rank Favorite first. - (alternately) If Favorite and Compromise are in the Smith set and Worse isn't, then I should make it count: vote Favorite first so as to help maximally against Compromise. - Only when all three are or will be in the set might I gain a strategic advantage by betraying Favorite, and I might not even need to (depends on u/a FBC). Here I *think* the probability would be so low that I wouldn't betray Favorite. However, that might sound like rationalization, so I'll explain at the bottom*. Now you might say that this is cheating because I'm refining u/a further to a Nader-Bush-Gore situation. But consider your reasoning for a moment. You say you're concerned about voters favorite-betraying in u/a, and you say current political elections in the US are u/a. So I don't think I have to consider u/a elections with n-way races n>3 because by the time that many parties would be viable, people would have got over their overcompromise anyway. But, maybe you _don't_ know that Compromise is the only acceptable who can beat Worse. Maybe you have no idea which one can beat Worse. Then what do you do? You top rate all the acceptables. The problem, of course, is in the majority of circumstances, when it's somewhere in between those two circumstances. Only if they're all in the Smith set, and then only if you want to escalate - to bet the advantage after you push the method to weirdness is greater than the loss at doing so in the first place. You continued: And finally, I'd give this hint: the moment it feels like the "other side" has somehow acquired a preponderance of people in denial, take a more Copernican view. When an otherwise sensible group holds a view that seems to be silly, and to explain the silliness, a greater part of that group needs to be extraordinarily blind (and very specifically so), perhaps they are not. Perhaps, instead, the view is not so silly. [endquote] It's hardly rare for a majority to be mistaken. It's common. You rely too much on polling. As I said, the configuration of advocacy on EM is but a snapshot of something that's constantly changing. I would hardly call the discussions on EM mere "polling". If they are "polling", then your discussions with the favorite-betrayers upon which you build most of your idea of FBC's necessity is also mere "polling" -- and polling with a much lesser sample size at that. As I've mentioned, Approval won the most recent EM poll on voting systems. Approval won by every method that we used. Approval was the CW, the Approval winner, and the Range winner. In the short list of Declaration signers, more people mention Approval than Condorcet, even if you count VoteFair as Condorcet. And one of the people who mentions Condorcet ranks it below Approval. True enough. You keep returning to Plurality vs Approval. My point, however, was that if otherwise reasonable people just so seem to happen to have a big hole where their judgement of Condorcet vs Approval is located, then it has to be awfully specific (and convenient) for them to be thus blind. And if favorite betrayal really is so rampant, then it is strange that so few other American EM participants have mentioned the need for absolute FBC to guard against it. You don't make it out to be a contested issue like say, left vs right, but rather something that is obvious: s

As I said in my previous mail. The Approval problems that I refer to are the well known and well discussed problems of the Approval method. They are quite separate from the "impact on the two-party system" oriented questions (where Approval and Condorcet behave in quite similar way). > In particular, you have never answered my question about what problem > Approval will have that Plurality doesn't have. Thanks, this is one concrete request that I can reply to. I tried to address also that question earlier but obviously my explanations were not good enough. If we study Approval and Plurality as separate single-winner methods, then maybe you aleady know all the discussions, maybe even too well. My opinion is that the biggest problem of Approval is the difficulty of voters to find a working strategy when there are more than two poential winners (e.g. when there are two candidates from one wing and one from the other). Also Plurality has related problems with strategy, but in Plurality (in a two-party system) a good strategy is to vote for one of the two dominant parties. In Approval the voter may not have any such safe strategy option. If we study Approval and Plurality as part of the proposed system where single-winner methods are used in single-member districts in a multi-winner election, then the answer is quite different. Then the key difference is that while Plurality is a key component that maintains the two-party structure, Approval aims at electing compromise winners that need not come from the two dominant parties. This may be good or bad, depending on one's point of view. Approval introduces a new non-classical and untested system, but that system may well be worth a try. Approval (and other compromise seeking methods) will have some specific features like the already discussed influences on the government stucture. > No one can predict exactly what the changes would be. > But they'd definitely be improvements.

In Burlington people, or possibly only politicians, wanted to go back to the old system. It is obvious that at least within the current dominant parties there is some interst to maintain their current powerful position. Regular people may be less interested in going back. But I think going back to the old system is a risk (or why not sometimes a positive option) in every reform. > I didn't observe any strong burial tendency in Burlington when I analyzed > those votes. > > [endquot] > > It was a municipal election. > > Did your analysis include looking at the labels on the ballots that told > what the voter really likes best?

If there is a general tendency to bury, that tendecy should be visible in those votes, and there should be a large set of votes that have ranked minor candidates above some of the (three?) most potential candidates. > You know what, I'm still only halfway through this post.

It's usually pretty obvious which candidates qualify. And I've discussed this more in my most recent postings here at EM: One: No one knows for sure exactly what way of voting (by hir and some hypothetical same-preferring and same-voting faction) will give the best outcome. That's true in Condorcet as well as in Approval. Two: In Approval, if you like strategy, I've given simple instructions for determining the way of voting that maximizes your expectation. I've described it for u/a elections, .and for non-u/a elections. Three: In Condorcet, you don't have a known strategy for maximizing expectation. In a u/a election you have, instead, a ridiculous dilemma, and no hint of what will maximize ..your expectation. In fact, in general, expectation-maximizing strategy is not available in Condorcet. I'll reply to the rest of your recent postings within a few days. Mike Ossipoff (e.g. when there are two candidates from one wing and one from the other).

You might say that it's a subjective matter. Maybe, but when you talk to most people who vote Democrat, they express disgust for the corrupt, sold-out, bribed (Republocrat) politicians.

In Condorcet one can sincerely recommend sincerity. In theory there are cases where one could cheat the system. But in practice sincerity is by far the best strategy that voters have in large elections where voters make independent decisions. The challenge is to find practical situations where regular voters, after hearing some poll results (and possibly some poll based situation specific strategic advices by the media), would have good reason to vote otherwise (in a way that they can master an that is likely to improve the outcome). If for these reasons strategy free voting becomes widely accepted, and a norm, we have a system that may serve the society well. > Two: In Approval, if you like strategy, I’ve given simple instructions for > determining the way of voting that maximizes your expectation.

That one determines how well Approval will work (after taking into account any additional facts like e.g. some tendency to bullet vote and possible situation specific strategic guidance). You mentioned also sincere approval of "approvable" canddates as a strategy that could be recommended to the voters. Do you think Approval can handle well situations where some voters or voter groups are strategic while some are sincere? > Three: In Condorcet, you don’t have a known strategy for maximizing > expectation.

Should A and B be seen as the expected winners with 50% winning chance both? Maybe 50% of the voters should guess that A wins and 50% that B wins (?). [example+question ends here] This is an unanswerable question about a preposterous situation, that *will not* occur in real public elections under conditions where elections even make sense. The population is entirely and completely polarized into two camps of almost equal size. No voters are intermediate in position, no voters have C as their second favorite. Essentially, there are no "independent" voters. Now, suppose that, nevertheless, we have such a situation. The problem boils down to two parties, with one having a slight edge over the other. The other, the slight majority party, is united. The majority party is itself evenly divided into two factions, supporters of A and B. Do they care about winning? From the stated preferences, yes, that is what >> means. Strong preference. If they care about winning, they will never let this situation go to an election, they will present a united candidate, even if they have to toss a coin to do it. That is what the Democrats *must* do if the method is plurality. That is why Plurality leads to 2-party systems. What is presented here is really a three party system, with the slight majority party being split into two factions. Parties that allow themselves to be split this way lose elections. Society itself, overall, it this situation, doesn't give a hoot. The SU of all three winners is evenly divided. So from what perspective do you want to advise voters? For obtaining their individually-maximized utility? Or for creating a socially beneficial result, which indirectly benefits *all* individuals, because a coherent society produces value for all members? So, next step up with improved voting system, what about Approval? From the stated preferences, A and B voters have a dilemma, but it is only a small one. If they do not unite, they risk losing to C, a big loss. If they do unite, they risk their favorite losing to their next-favorite, but by the terms of the problem, this is a smaller loss. They maximize expected personal utility by approving both A and B. If they get greedy, and only go for their favorite, they risk loss to the least-favorite, by far. They would, basically, deserve this loss. The reward of greedy stupidity is loss. From the point of view of overall social utility, this election could go to any of the three candidates and be approximately the same utility. Hence the method I'd want to see for this election is Score voting, if we must have a single poll. Bucklin would work fine, though. Bucklin allows voters to stand, for the early rounds of counting, for their favorite, while uniting before the election is over, if it's needed. The votes would presumably be 26:A>B or A>.>B 26:B>A or B>.>A 24:C or C>.>A 24 C or C>.>B (the period represents a blank rank. This was actually used in the Bucklin elections, it's clear. Some voters postponed compromising until the last rank.) I'd say that Bucklin handles this election perfectly. A tie is unlikely, because voters will vary in how they add additional ranking. What determines how the voters actually vote is preference strength. A good answer to this question would solve many of the Approval strategy related open questions. (Working Condorcet strategies still to be covered.) What should an individual regular voter do in the given situation? How do they identify their best strategic vote? It's obvious. Real voters will have little or no difficulty if they know the situation. There is no remedy for ignorance, though. I do have some question about designing voting systems to empower the ignorant. (By the way, that is *not* an elitist position, I'm ignorant, often, and systems that give equal weight to my ignorant opinion can make some poor decisions. Choice is another matter, but I won't go into that, beyond noting the important issue of consent to results, the reason why I strongly support systems that require majority consent for a result, directly or, if not directly, if that's not possible, then indirectly.) That situation is quite common, except that acc

However the general set-up where one wing has two srong candidates, the other one has one, and the balance between the wings is close to 50%-50%, is a common se-up that all good methods should be able to handle.

If Approval can not handle three potential winners, then making sure already before the election that there will be only two potential winners would make the common Approval strategies work.

Re: [EM] To Condorcetists:
Now I have a reasonable definition of Mike Ossipoff's strategy that is supposed to be valid for all Condorcet methods (and even for all FBC failing methods). The strategy is "if there are winnable unacceptable candidates and winnable acceptable candidates, find that winnable acceptable candidate that is most likely to win all the unacceptable candidates, and rank him alone at top". Here use of terms acceptable and unacceptable means that the voter has some higher than marginal interest to make one of the acceptable candidates win instead of the unacceptable ones. Let's study it in the US framework. I'll use the Republican candidate, the Democrat candidate and Nader to describe what could happen. The key idea of the strategy is that the voter can bury his non-winning favourites (Nader) without concern since they will not win anyway. The strategy says that the voter may bury also winnable favourites if another acceptable candidate is more likely to win all the unacceptable ones (not covered in this example). The reason why this burial might benefit the voter is that there might be an intentional strategic loop caused by other strategists (Republicans), and that strategic loop could make R win instead of D. Alternatively there might sometimes be also a loop caused by sincere votes. I'll address some reasons why the strategy might not be on optimal strategy for real life elections to be applied always in all Condorcet elections. 1. Nader supporters would lose the benefits of ranking their favourite first: There are benefits to voting for your favourites also when those candidates can not win. The Nader voters have obviously already today some reasons to vote for Nader in Plurality elections although Nader has no chances to win. The voters maybe want to lift the political weight of Nader and his opinions, or make him or his followers win in some future election, or they may just want to carry a message that they do not like either one of the current major parties. They do so although their vote is likely to help the Republican candidates (the worst winnable candidate). If the election method would not punish them as much as Plurality does (e.g. Condorcet), Nader voters would probably be even more interested to show support to their favourite. It thus doesn't sound like the Nader voters would be happy to bury their favourite if the election method was changed from Plurality to Condorcet. In real life elections optimality of a stratgey is not measured only in terms of who is the winner of this election but in some much wider sense. 2. The marginality of the benefits: If the Republicans decide to strategically bury the Democrat under Nader, when Republicans have 48% support, Democrats 42% and Nader 10%, more than 42/48 of the Republican voters should follow the planned strategy and vote R > N > D. This is not probable. So the Nader voters have no reason to worry. The benefits of ranking their favourite first will be more important than the need to defend against a possible strategy that is not likely to materialize.

Re: [EM] To Condorcetists:
[I rewrote the message whose draft version I sent out earlier by mistake.] Now I have a reasonable definition of Mike Ossipoff's strategy that is supposed to be valid for all Condorcet methods (and even for all FBC failing methods). The strategy is "if there are winnable unacceptable candidates and winnable acceptable candidates, find that winnable acceptable candidate that is most likely to win all the unacceptable candidates, and rank him alone at top". Here use of terms acceptable and unacceptable means that the voter has some higher than marginal interest to make one of the acceptable candidates win instead of the unacceptable ones. Let's study it in the US framework. I'll use the Republican candidate, the Democrat candidate and Nader to describe what could happen. The key idea of the strategy is that the voter can bury his non-winning favourites (Nader) without concern since they will not win anyway. The strategy says that the voter may bury also winnable favourites if another acceptable candidate is more likely to win all the unacceptable ones (not covered in this example). The reason why this burial might benefit the voter is that there might be an intentional strategic loop caused by other strategists (Republicans), and that strategic loop could make R win instead of D. Alternatively there might sometimes be also a loop caused by sincere votes. I'll address some reasons why the strategy might not be on optimal strategy for real life elections to be applied always in all Condorcet elections. [The rewritten part follows.] In this example we can assume that the candidates are roughly positioned on a one-dimensional left-right axis where the order of the candidats is N, D, R. 1. What will Nader supporters lose if they bury their favourite: There are benefits to voting for your favourites also when those candidates can not win. The Nader voters see obviously already today some reasons to vote for Nader in Plurality elections although Nader has no chances to win. The voters maybe want to lift the political weight of Nader and his opinions, or make him or his followers win in some future election, or they may just want to carry a message that they do not like either one of the current major parties. They do so although their vote is likely to help the Republican candidates (the worst winnable candidate). If the election method would not punish them as much as Plurality does (e.g. Condorcet), Nader voters would probably be even more interested to show support to their favourite. It thus doesn't sound like the Nader voters would be happy to bury their favourite if the election method was changed from Plurality to Condorcet. In real life elections optimality of a stratgey is thus not measured only in terms of who is the winner of this election but in some much wider sense. 2. What will Nader supporters win if they bury their favourite: If the Republicans decide to strategically bury the Democrat under Nader, when Republicans have 48% support, Democrats 42% and Nader 10%, more than 42/48 of the Republican voters should follow the planned strategy and vote R > N > D. This is not probable. So the Nader voters have no reason to worry that ranking Nader first would help R to win D. Nader supporters could cancel the Republican strategy (and thereby make their compromise candidate D win instead of R) by burying their favourite, but in practice the Republican strategy is not likely to happen nor be successful if it would be attempted. With high probability there will be no benefits. The proposed strategy seems to be based on the theoretical vulnerability of Condorcet methods to the burial strategy. One should however clearly separate theoretical vulnerabilities from what is likely to happen in practical elections. Also in this example it seems that in practice the benefits of the strategy reman at theoretical level while the benefits of sincere voting and ranking Nader first would be lost right away if voters would follow the strategy. It is not likely that Nader supporters would consider it beneficial to "betray" their favourite. Are these arguments sufficient to "prove" that the proposed strategy would not be optimal for the Nader supporters of this example. (Also the "Condorcetists" are welcome to pont out possible holes in the arguments.) Juho Election-Methods mailing list - see http://electorama.com/em for list info
