SACRW2: Score And Choose Random Winner from 2 complementing methods
-
I favor your idea in general.
In addition to the procedures you mention, Majority Judgment and STAR could be added. Why not use four methods?
I particularly like your idea for the ceremony featuring a child making the random selection. I think it would appeal to citizens' emotions and make them feel solidarity around the overall method.

after a few adjustments I would change this to:
RWLCP: Random Winner from a List of Complementing Philosophies
A hybrid design for a single winner winner systems that combines some aspects of different voting-philosophies without predictable results for strategizing. So (succesfull) strategizing would not happen much. Also importantly the randomization would be perceived by normal citizens (as non voting-experts) to be a fairly honest choice between different kind of winners which all have a fair case to say they are legitimate and have a mandate. It could also lead to a bit more humbleness in the winner instead of arrogance because the winner would know he had an element of just luck on their side.
steps:
- start with a ballot that's suited to gather all needed info
- use independ and different methods to suggest a single winner:
- ends by picking the ultimate winner from the combined set of suggested winners (lets make that symbolical and festive: a little schoolchild chooses blind)
- the ultimate winner is announced
-
In order for such a system to effectively deter strategic voting, the best strategies in the component systems used need to be sufficiently different. Otherwise common vulnerabilities still can be exploited. The most useful strategy in Score and Condorcet is usually exaggeration, so I am skeptical that the two systems effectively complement each other.
There is also a risk that mixing many systems in this way could compound their strategic vulnerabilities rather than offset them.
Strategic voting in Condorcet methods often attempts to increase the size of the Smith set and force cycles. The same strategies could be used with this system since the size of the Smith set also indicates how many winners the Score-based methods are expected to return. Random selection can be exploited by running many similar candidates, since when the Smith set contains multiple candidates, cloning a candidate in the Smith set would cause the clone to be added to the Smith set.

You'll never get lay people on board with a blatantly non-determinative method. If a blatantly non-determinative method was implemented, people wouldn't vote because they would feel, even more so than they already do with FPTP, that their vote doesn't matter.
-
@Sass Agree that anything with randomness is bad. Can't speak to people's incentives to vote though. Having some degree of randomness doesn't necessarily make their vote "matter" less, at least not from a game theoretical point of view. Still I think anything with true randomness would never fly in any real world political election.

On what grounds you come to that prediction? There is randomness in filling jury pools, and what juries do is extremely important as innocent people could be punished by the mechanism of the state. Moreover, people who I suppose have a libertarian bent, or at least, a mistrust of officialdom, keep suggesting, on Facebook, sortition to fill legislative seats and executive office in gov't.

Why not? If the two methods elect the same person almost all of the time, while choosing between them randomly makes strategy impossible, people will understand.
I've often wondered about such a system, and if it provides a workaround for Gibbard's theorem. Design two voting systems that behave consistently if people are honest, but behave oppositely if people are strategic, and choose between them randomly, so that no one can predict whether a given strategy would help them or hurt them. I don't think you can pick two existing methods, though, I think you need to specifically design them to be contradictory.

@Psephomancy I can't speak on behalf of other countries, but Americans are so used to voting strategically that they're having trouble understanding the concept of a voting method that allows honest voting, let alone one that encourages it. The Equal Vote Coalition was a bit bewildered when folks we're only scoring two or three candidates on STAR ballots in some early tests. The voters just had trouble internalizing the idea that they could support multiple candidates. If you try to tell voters you have a method that picks a random winner if they vote strategically, they won't understand it and the media will latch onto "random winner" and ignore everything else. I support systems that incentivize honest voting, but that can be done with many existing methods that don't rely on randomness.

Good luck explaining the Smith Set to lay voters. -
Introducing randomness into an election is a bad idea on so many levels. For instance, what if you have a recount? But just the general idea of it will be, and should be, offensive to many. This is not the same as picking a jury, obviously. (a jury is supposed to be random)
I'm sure voters can wrap their heads around the idea of a system that doesn't punish honest/sincere voting. Some will still try to vote strategically for a while, but those voters will essentially average out and not cause a lot of harm. The main point is that a system that favors honest voting.
I suspect the reason people only scored a subset of the candidates (in STAR elections, I guess) is that they didn't know anything about the ones they didn't give a score to. That's exactly what I'd do... just give them all an implicit zero. Even though I fully understand the idea of supporting multiple candidates.

honest/sincere voting
Please consider the following system. The voters submit 32 hex digits as their vote. The tally sorts the votes, concatenates them together, and computes the SHA 256 hash of the whole. It interprets this result as an integer and divides the count of candidates into that. The remainder is used to indicate the winner.
Which votes are sincere?
Approval-ordered Llull (letter grades) [10], Score // Llull [9], Score, STAR, Approval, other rated Condorcet [8]; equal-ranked Condorcet [4]; strictly-ranked Condorcet [3]; everything else [0].
-
I misread your original post. I was thinking, collect rating ballots, use methods each of which is designed to pick a single winner, and choose at random from among the winners that the methods identify.
-
@Jack-Waugh It sounds like you simply described a random voting system with the 32 bit hex thing. Not sure what you're after here. I don't think your vote can be sincere when the voter doesn't know how to do anything other than put a random number down.
Regardless, I'm saying no one is going to accept a voting method with randomness in it as you describe, even with your more reasonable options. It is a non-starter.
That said, I think several "reasonable" methods are hard to say what a sincere vote is, Approval being the most obvious one. But a ranked method it is pretty straightforward to determine what a sincere vote is.
-
@Jack-Waugh I think it is difficult to define a sincere vote as something completely isolated from its effects on the outcome, since I think that those effects are what give votes "meaning". Imagine a Score voting system where whoever had the fewest points wins. A "sincere" vote under this system might be the exact opposite of a sincere vote under standard Score voting.
Under a system where the effects of your vote are be completely unpredictable, like the hashing one you described, I don't think your vote is capable of expressing anything about your preferences, since there is no way to tell in advance what any vote actually does.

True, but with ranked methods, I think we can pretty easily define "sincere" to mean that you ranked them according to your actual preferences. Likewise under plurality, if I preferred Ralph Nader to Al Gore (in 2000), but voted for Gore because I thought Nader didn't have a chance, and preferred Gore to Bush... that's an insincere, strategic vote.
One shortcut to deciding what is a sincere vote is if you actually would vote the same way if you truly had no idea which of the candidates is more likely to win. If so, that is (in all cases I can think of) a sincere vote.
