Public ballot-imaging solves the problem.)<br><br></div><div>Also, each local or intermediate regional assembly could use whatever voting system it wants to. It wouldn't be necessary for any national agreement on a voting-system, or any agreement on a voting system other than within any particular local or intermediate regional assemblly.<br><br></div><div>Of course, if desired, there could be a national agreement on a voting-system.<br></div><div><br></div><div>In fact the voting could (but of course needn't) be by show of hands.<br></div><div><br> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div> And to do this, starting from the relatively simple criteria for evaluating voting systems that we still seem to have lots of disagreements about, can we somehow leap beyond that narrow view to say much at all about how the voters, candidates, and society as a whole will change in response to the constraints imposed by the voting system? We need to try to do this, right?</div></div></blockquote><div><br></div><div>The existence of democracy at all would make a much bigger difference than the matter of which good voting-system is used. A good voting-system is part of democracy, but the crucial requirements are verifiable, and thereby honest, vote-counting, and an honest, open, participatory, and agenda-free media system.<br><br></div><div>Other than saying that the country would be incomparably better if we had democracy, there's little that can be predicted.<br><br></div><div>I suspect that there would soon no longer be any such thing as a strong bottom-set.

Can we do better now?</div></div></blockquote><div><br></div><div>There's no need to get rid of political parties.A party consists of a section of the population that summarizes its proposals in a platform. There's nothing wrong with that. It simplifies voting, with relatively few platforms to choose from.

A method that has chicken-dilemma could sometimes have a bit of confrontation and non-cooperation between factions that need eachother's help, though that would be just in temporary instances.<br><br></div><div>But I don't call chicken-dilemma a "problem" for Approval--only a nuisance.<br><br></div><div>Obviously a method that meets FBC will elicit more sincere ballots, and will progress faster toward what people want.<br><br></div><div>So I suggest that the best voting-systems are those that meet FBC & don't have a chicken-dilemma problem.<br><br></div><div>I said that I agree that Approval is the best. When a chicken-dilemma-proof rank method is used, the best way for a voter to use it is to use it as Approval, at least when there are strong top & bottom sets. ...ordinarily using only top & bottom rank. ...but using 2nd-rank demotion for chicken-dilemma defection-deterrence.<br><br>And when such a method is used in that way, it can be regarded as an Approval version, which means that it can still be said that Approval is the best.<br><br></div><div>Without strong top & bottom sets, maybe it could be desirable to vote a full ranking.<br> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>, at the level of an atom, and what we can build out of it depends critically on which atoms we have available to us.

I would expect that repeated applications of Approval Voting will result in having more candidates run who will appeal to many more voters. We're not used to thinking in terms of the broad appeal, such as what Bernie has gotten, and he had a huge struggle just getting noticed, at first. I expect more like Bernie will come out of the woodwork if they were rewarded for doing so.</div><div><br></div><div>Anyway, the result of having more candidates that most voters like is that it won't matter so much that there are three candidates who are close enough in popularity to possibly result in a surprising win by the slightly less popular candidate. </div><div><br></div><div>Then again, the chicken dilemma might be a motivation for cooperating between similar candidates to pick one of them rather than letting all run.

Factoring in the long-term emergent effects of each voting system.<br>2. An example of how Approval Voting results in better long-term effects.<br><br>Among the many criteria for evaluating voting systems (<a href="https://en.wikipedia.org/wiki/Voting_system#Evaluating_voting_systems_using_criteria" target="_blank">https://en.wikipedia.org/wiki<wbr>/Voting_system#Evaluating_voti<wbr>ng_systems_using_criteria</a>) I don't see any that address the long-term effects of using each voting system. In other words, the effect on one election is certainly important, regarding the satisfaction of the election results by voters and candidates. But I would argue that it is even more important to consider the long-term effects that emerge when applying a voting system repeatedly over many elections. A small bias one way or another may not be very apparent if you only look at one election, but over may elections, they can add up and perhaps compound the bias exponentially.<br><br>There are many long-term effects to consider, but in particular, I am thinking of one pernicious problem: the tendency for two major parties to emerge and dominate all politics which results from the repeated application of plurality voting. This problem is fairly easy for most people to understand, although I am surprised to see that there seems to be a lot of denial about this effect as well. Some would even defend having only two major parties, or very few parties. That is an interesting subject to discuss, but regardless, I believe we should be aware of how our choice of a voting system will affect things over time, how society is likely to evolve based on the rules we lay down, and in fact, how it is actually very likely that the dominant forces in society will quickly and vociferously defend whatever rules resulted in their rise to dominance.<br><br>But back to this one question, studies and long-term experience have shown that other voting systems besides plurality, in particular IRV, also result in the dominance of two major parties. This may be more surprising to people, but looking at the underlying cause, it seems we can make a rather important simplifying argument about most voting systems regarding this problem. I would assert that the underlying cause of this problem of two-party dominance in any voting system is that it gives voters the ability to rank or order at least one candidate higher than the rest.<br><br>The reason this ability to rank candidates becomes a problem is the spoiler effect, where voters will have a strong motivation to give their highest rank to one of the leading candidates. If they don't, then they weaken the chance of that candidate winning and therefore strengthen the chance of the less preferred leading candidate. Because one of the leading candidates is likely to win, all the rest of the rankings of non-leading candidates hardly matter at all. <br><br>In any election, there will be two candidates who are the strongest in terms of popular support, and thus the most likely to win. Consequently (to grossly over-simplify the process) with any voting system that permits ranking, groups of voters will tend to coalesce around support for these two leading candidates to encourage everyone to support their preferred leading candidate. Eventually two major parties arise, and everyone who doesn't join one of these two major parties is excluded. <br><br>So once voters and candidates figure this out, any such voting system ends up devolving into the dominance of two major parties that we get with simple plurality voting. In fact, one might argue that plurality voting is better just because it is simpler.<div><br>But Approval Voting avoids this problem. Equal-rank approval votes mean voters don't get the option to express their preferred ranking, but because of that, they aren't at all motivated to bias their ranking dishonestly. They only have to decide which candidates to approve, or where the cut-off is between approval and disapproval.<br><br>Given that there are, as before, two leading candidates, how does Approval Voting affect whether one of those two leading candidates will win? One of the two leading candidates is likely to win even with Approval Voting, so it would appear there is no benefit, but that would be a short-sighted way to judge a voting system. In subsequent elections, it would seem likely that more candidates will run who have broader appeal to ALL voters, not just a majority or plurality. Because the winning candidates will be those who are most approved of by the most voters, there will be no value in parties that typically focus on appealing to no more than half of the voters.<br><br>So I suspect the long-term use of Approval Voting would be self-correcting toward better and better representation of ALL voters, not just half the voters, because in each election, almost all of the voters contribute to choosing the winning candidates, and that only gets better over time as the candidates who decide to run get closer to receiving the approval of all voters.<br><br>Can any other voting system claim a similar long-term effect? Even a voting system with three ranks, e.g. Approve, Neutral, Disapprove, would encourage voters to approve one of the leading candidates, and give neutral or disapprove votes to the rest. I wonder if Approval Voting might be the ONLY system that has this long-term effect.<br><br>What I am aiming for is a voting system that self-corrects over time. No matter what voting system we choose, there is probably always going to be at least some small bias, some inequities or incompleteness. So we need to understand this and deal with it.<br><br>But one important question should not be overlooked: What do we want to self-correct toward? That is, what is the long-term goal? I believe we should want to move toward a closer or better representation of society as a whole, but there are other ways to look at that.</div><div><br></div><div>Looking forward to reading your feedback.<br><br>--<br>Daniel LaLiberte<br><a href="mailto:daniel.laliberte@gmail.com" target="_blank">daniel.laliberte@gmail.com</a></div></div>
