IRV is more complex in every way than STAR voting. STAR is just score with a single automatic runoff. It gets everything you are talking about in terms of intuition, explanation… everything you like about IRV is present in STAR and basically everything wrong with IRV is fixed by STAR.

I think the idea of rating candidates vs voting for them could be less intuitive and feels more complex, though there isn't any reason you couldn't just change it to 'rank candidates in order of preference 1-5, candidates may tie' or something. What it's missing compared to IRV is that you can't go, it's just like what people already do (runoffs), just in a single round.

  It's true that ratings can feel a little harder to grasp, but just any concrete experience with the system, it's easy to get. Check out http://star.vote/ http://star.vote/ and try for yourself. In STAR, 5 points is simply "most points" i.e. most support. It doesn't mean something semantically. You can give up to 5 points, like if there's a race, you can push each candidate forward as much as 5 steps. The only thing it means is that you pushed them forward more than another candidate. That's not that hard to get intuitively. IRV is not what people already do but in a single round, it's much more complex than that. And whoever's 1st choice in IRV loses in the final round, they (and that could be as much as 49% of the voters!) never get any of their other preferences counted at all, unlike either STAR or our current two-round system.

    > In STAR, 5 points is simply "most points" i.e. most support. It doesn't mean something semantically. Yes, so you import the well-known cultural variation in numeric rating systems without concrete semantics for rating levels into your voting system. That's a great idea. More data on ballots is good only as long as it has a consistent meaning and is used in a way that is consistent with that meaning. STAR (and other score voting systems) gather noise and pretend it is signal.

      STAR gathers scores that voters choose when looking at the pool of candidates. It uses those in tabulating the outcome. They have an effect. There's no sense in which this is noise. I don't even understand the claim.

    I looked at the website. STAR Voting allows voters to rate all the candidates similar to how we rate books on Amazon Ah yes, Amazon, that site with famously reliable and unbiased user reviews. This is a terrible idea. It’s a bad voting system made worse by appeal to similarity with popular apps and websites, which themselves use a really bad voting system.
    - quadrangle 8y ago
      It's not a terrible idea, it's a bad metaphor from imperfect people trying to explain a perfectly fine idea. STAR voting is NOT like rating books on Amazon, it's just superficially similar. At Amazon, if you don't like any of a bunch of books, none of them get 5 stars. With STAR voting, you award points not to mean anything, but only to decide how much ahead in the race you want to push each candidate versus the others. Whoever you want to win most, you push them ahead with all 5 available points. That's it. Your reaction and misunderstanding does further my annoyance at the people explaining STAR using the Amazon analogy, and I think that bad comparison is harming support for what is truly an excellent voting system.

        I’ll admit I didn’t read much further than that, yeah. It’s possible it’s a good system and I’m just put off by the unfortunate comparison. My issue with all of these point- and range-based voting systems is that when you see the results, you might want to tweak your scores. Let’s say I’m range voting out of 10 and I give four candidates 1, 3, 8 and 10 points respectively. But the candidate I rated 3 wins, with the candidate I rated 8 a close second. Damn it! If I’d known that was going to happen, I would have voted 1, 1, 10, 10. So with extra information, range voting boils down to approval voting, and I think it all ultimately becomes ranked voting. It’s hard to imagine any scenario where I would want to change my rankings, even if I have information about the results. If I like both candidates A and B, but A slightly more, I’ll always put them at the top of my list and in that order. Now, it’s true that in IRV there are scenarios where I can get a better result for myself by voting for candidate ranks in a different order; but those are rare (I think) and definitely unintuitive. In the example above, if B were a real long shot candidate, it might be worth ranking them above A in case B gets eliminated early. But it’s unlikely to make a big difference because, you know, B is a long shot. And that’s just IRV; other ranked voting systems are much more robust.

IRV has problems, but complexity, intuition, and explanation are not three of them. Intuiting what "giving one star more or less to a candidate" means is really difficult to understand as a voter. "If more voters had given Kodos four stars instead of three, he could have won" is a headache inducing explanation. Approval voting is the only alternative to IRV or plurality voting that seems to match the level of intuitiveness of both the voting process and the tabulation process.

  The way to turn ballots into results is just a simple division, numerator (sum of scores) over denominator (number of voters). Try to explain to me the function from ballots to results in IRV with 5 candidates in as simple of terms? It's absolutely much harder to analyze IRV and predict what is going to happen. In every range voting scenario, I can show you a bunch of ballots and you could quickly figure out the smallest change required to make a different person win. With IRV, I imagine you'd first start by drawing a big tree of options, and then simulating every way each could play out...
- quadrangle 8y ago
  I seriously doubt that anyone would get a headache over "if people had given that losing candidate higher scores, they would have won". I don't even see how you can honestly claim that to be anything but completely intuitive to everyone. If IRV complexity and explanations were not a problem, we wouldn't see today's reality where IRV proponents themselves constantly make incorrect claims about it. Not always (and not in the linked article here), but often people get the intuition that their 2nd choice will get counted when their 1st choice is eliminated, and then try to get them to understand why their 2nd choice was not counted (because their 2nd choice had already been eliminated) while someone else's 2nd choice was counted… What happened in Burlington before they repealled IRV shows not only people getting intuitions about IRV wrong but people often don't even get what happened in Burlington because it seems so counter-intuitive. https://www.equal.vote/Burlington https://www.equal.vote/Burlington And yet, that scenario is common enough. Burlington is just the case where all the ballot stats were released so we can study it.

All score methods are bad (especially in a large multicultural polity) because mapping from subjective opinion and preference to numeric scores is inconsistent and, particularly, highly culturally variable. If there were an objective way to measure actual utilities, score-based methods would be great (and economics and policy assessment would be much simpler, and...)
- quadrangle 8y ago
  There is no such mapping, especially with STAR. So, the critique of scoring based on mapping being variable is fundamentally a misunderstanding. In STAR voting, you have up to 5 points to give to each candidate. You effectively get to push each candidate ahead in the race relative to the others by as many as 5 steps forward. There is NOTHING subjective about the meaning of points. They are just points. More points wins. They have no cultural signficance, no opinion, nothing subjective.
  - dragonwriter 8y ago
    > There is no such mapping, especially with STAR. Yes, there's a mapping to a (typically 0-5) numerical rating like those popular in online review systems, which is a motivation for the forced acronym, and exactly the similarity that is viewed as making it particularly intuitive and accessible. Cultural differences in how such rating systems are used for similar preferences have been studied considerably. It's true that you can also view STAR as a limited bucket (and so forced-tie for any but the smallest candidate pool) ranked-ballot method, in which you force voters to arbitrarily select which intercandidate ranking preferences to suppress, and then do a completely wacky (from a ranked preference perspective) method of tallying the ballots.
    - quadrangle 8y ago
      It's unfortunate that the branding emphasizes the bad-to-good popular ratings metaphor. I agree that is a problem. It is indeed a form of ranking that allows ties and has a limited resolution. But the limited resolution does help with simplicity. From a UI perspective, presenting a ranked ballot that allows ties is unfortunately complicated. That's what STAR actually could/should be though. And the tallying method is fine, not wacky. In a sense, it's like Borda Count to get to two finalists and then IRV for the finalists. That avoids all the worst aspects of IRV (which are all symptoms of the way its multi-round elimination ignores the preferences of many voters while counting the preferences of others).
