Which voting system is the best? - Alex Gendler

Dive into four different voting systems: plurality, instant runoff, tactical, and the Condorcet method, and find out which is fairest.
--
Imagine we want to build a new space port at one of four recently settled Martian bases, and are holding a vote to choose its location. Of the 100 colonists on Mars, 42 live on West Base, 26 on North Base, 15 on South Base, and 17 on East Base. Assuming that everyone wants the port to be closest to their home base, what is the fairest way to conduct the vote? Alex Gendler digs into voting systems.

    @@jacobandrews2663 DV eliminates the worst candidate by redistributing the points, so if you give all 100 points to a candidate who is eliminated among the first, the vote becomes irrelevant. To avoid this it's better to distribute the points. Also, you consider that using range [0,10] (then converted to 100 point votes), it's difficult to accumulate points.

    One thing not mentioned in this video is that plurality voting also "incentifizes lying about your preferences" not just multiple rounds. This happens (kind of) in the US, where people might want to vote for a third party (ex. green party, libertarian party, etc.) might end up voting for the democratic/republican candidate because they think that the third party they support is unlikely to win.

    And it gets worse - not only does supporting a third party not help them win, but it also draws votes away from the major party you otherwise would have supported. Too often, this leads to your worst option getting elected. I like to describe Plurality as mathematically driving us to a two-party system, and this is why.

    An active refusal to vote with a nuanced understanding of the position is a refusal to give your consent to the government. DO not blame the victim. If you look at Martin Luther King Jr, he would not have supported voting as a means to make your voice heard. He supported civil disobedience to accomplish that end. Particularly in his later years. Organized and sustained social movements accomplish things voting has always managed to suppress.

    This system isn’t really a voting system like the ones in this video since it uses systems like first past the post to determine candidate winners and party seats are made proportional to the votes they receive. This seems to be less of a way to determine winners and more of a way to allocate power among the parties and individuals that do win.

    @Kurt E. Clothier In both Australia and New Zealand there are many parties but only 3 or 4 regularly win seats, the other minor parties are often single issue parties somewhat like lobbies. The competition for government boils down to 2 major partys, centre-left vs centre-right. If the voting system changed Americans would likely see the Greens and Libertarians grow and maybe a split between the Tea Party and GOP. But the major votes would still be between the Democrats and Republicans. From an outsiders view, one of the weirdest things about American politics is the 2 major partys aren't left and right, but centre-right and right-wing.

    I think Borda Count, although not perfect, would probably be the best option. Convert the rankings into points, so a first choice gets 3 points, a second choice 2 and a third choice one, and the winner is the one with the highest overall score. It therefore elects the overall most popular/least unpopular option. In this example the winner would be North, which on the map does look like the best compromise. Admittedly two of the methods demonstrated also make North the winner in this example, but the problems with both are discussed.

It puts each candidate head to head, and if there's a candidate who's able to beat every other one in a one on one match (and is thus a Condorcet winner), that candidate wins automatically. Otherwise, it plays by the same rules as the Borda Count system.

    I'm shocked to see no discussion here of range voting, in which voters give each option a score, say from 0 to 10. Key advantage: the theorem mentioned (Arrow's impossibility theorem), which proves that "all voting systems violate certain common sense fairness intuitions" applies only to "ordinal" systems, where your either pick a favourite or put options into preference order. Range voting is a Cardinal system, so this theorem doesn't apply. To see how it works, suppose all the Martian voters give 10 to the closest location, 7 to the next-closest, 4 to the third, and 0 to the furthest away. The most "central" location, North, wins - and this seems fair, since no-one scores it zero - i.e., it isn't any voter's least-favourite option (the same is true for South, but there are more people in North). If someone were to propose an "optimally central" location between the 4 Mars bases, to minimise the average airport travel-distance per Martian citizen, I would expect this proposal to beat North in a Range Vote, just as it should. In most other voting systems, such an obviously-fairest solution would almost certainly fail. It's worth mentioning that Star voting, cited as an example of voting systems to which the Arrow theorem applies, is actually a modified version of range (or "score") voting. The author really ought to know this!

Plurality voting and the various ordinal systems can all do that.

The only theoretical advantage of Star is when there is a much higher level of strategic voting than is ever actually observed in real-world practical studies of score voting. That said, Star is better than all the ranked-choice options, as well as FPTP.

    IRV is pretty good, but you might want to take a look at this page: en.wikipedia.org/wiki/Template:Comparison_of_Schulze_to_preferential_voting_systems IRV fails a bunch of criteria that I would personally consider important. For starters, IRV isn't monotonic, meaning that in some cases, ranking a candidate higher can prevent them from getting elected, and ranking them lower can get them elected where they otherwise wouldn't have been. It's also not a Condorcet method. Condorcet isn't a voting system, it's also a criterion. A voting method can be called a Condorcet method if it elects the Condorcet winner if there it one. It's where there _isn't_ one that they diverge. I believe Ranked Pairs is pretty good. It takes every possible matchup and ranks them by the percentage with which that matchup was won. Then you go down the list, "locking in" each candidate's relative ranking. When a result would cause things you become circular, you flip it. Since you start with the greatest victories, the people whose preferences are ignored (i.e. when a result is flipped) it ignores the least possible amount of people. Still, it seems like you've thought about this a lot, and ultimately you should go with the system you think is best (for example IRV has later-no-help and later-no-harm which many others don't). After all, what's voting for if not choosing the best out of a set of people's preferences? I wish you the best of luck this autumn.

But statistically, the will win the majority of elections, with minority views also wining a proportion of the time.

A politician must then, before anything else, get a thorough check for his position on the map. This could help clarify where they stand on certain issues. Huge questionnaires would have to be conducted, scaling what people think is most important. The size of the issue on the map could be its importance, the length and direction from the origin could be how much it matters for a specific party and which party the issue matters for. Most definitely doesn’t work in practice, but could be fun to test the idea

But instant runoff is probably the antidote for this because based on preference there will always be someone that gets a majority of support. In US elections this is how you can help ensure that whoever is elected has a majority of support. ME already does it and it works.

    Just take the rankings from 1:22 and assign points for each vote. For example: 5 points for someone's first choice, 3 for their second, 1 for their third, and 0 for last. Doing this results in North winning, South finishing 2nd, West finishing 3rd, and East finishing last. Almost all reasonable point values (eg. 3 for 1st, 2 for 2nd, 1 for 3rd, 0 for 4th) end in the same result. I was only able to get a different winner once I made 1st place votes worth 4x the point total of 2nd place votes, which would obviously be absurd.

    In the instant runoff scenario, if you add the votes up like points, awarding no points to the least favorable position and three points to the most favourable position, two points to the second most favorable, and 1 point to the third most favorable (per voter) the North base comes out on top.

    I like ranking and the weighting votes. So for this example, each colonist’s first choice would receive 4 points, second 3 points, third 2 points, and first 1 point. You add up each choice’s total points, then the highest is the winner. So: West= (42*4) + (15*1) + (26*1) + (17*1) = 226 East= 207 North= 294 South= 273 So North would win, which makes sense because it is the most central to all the colonies. It’s not a perfect system, but it seems better than the electoral college at least.

    For Condorcet, if you do get a loop like that, there are ways of resolving it, either baked into the system, or using a secondary system to pick from that loop (known as the Smith set). What you can also consider is what kind of tendencies a voting system has. FPTP, especially if it is a regularly held vote with the same or similar candidates, such as typical elections, has a tendency to result in effectively a two-party system because it creates situations in which only two parties/candidates have a reasonable chance to win. Instant Runoff has a tendency of the centre-squeeze, that is, centrists often receive fewer first place votes and are squeezed out, and split over the more extreme candidates, even though most would probably consider them a reasonable option (albeit not necessarily their favourite) and prefer it over the other extreme. Condorcet has kind of the opposite effect, and is more likely to elect moderates who may not be many people's first choice, but who are deemed reasonable by most, and preferable by a (varying) majority to every other candidate. Two round systems can kind of go either way depending on how people (tactically) vote: if a centrist and an extremist go to the second round, the centrist usually wins by getting the votes from the other end's extreme (unless there is something going on where people prefer any anti-establishment extremist over an establishment centrist), whilst if two extremists go to the 2nd round, then the centrists are squeezed out and forced to pick one of the extremes. For picking something like a president, having a more centrist uniting factor may be preferable, and thus Condorcet would be preferable, but for picking local representatives for a national level (e.g. UK constituencies), it may be less ideal as it would cause mainly centrists to end up representing the population, rather than being more representative of the varying views in the country (but then again, electing local representatives for a national level is generally bad at being representative of the differing views that exist within society; you need something more proportional for that).

    Instant runoff guards well against the spoiler effect, e.g. a third party candidate coming in from the fringes and stealing votes from a more moderate candidate. They will typically get eliminated first, and their votes redistributed as if they had never run. However, it doesn't guard well at all against a centrist candidate being squeezed from either side. Centrists will also be quick to depart the race. In the end, you still have the same two-party system that Plurality incentivizes.

    I'm not sure if this system also exists, but a voting system that seems alright to me would be using the ranking that we saw for the "Instant runoff voting" system, but instead of counting the votes in the way that was shown, instead, each voter's first place vote would be worth 4 points, their second-place vote would be worth 3 points, third-place would be worth 2 points and last place would be worth 1. Then, we would add up all the points for each place. If this method is used, then East actually ends up with the least amount of points and North ends up with the most points.

This was everyone has a say you still have a local member and internal party politics doesn't affect candidate placement.
