The Steering Council election recently concluded, using a new voting method and voting service. It’s fair to say it was a success by any measure. Here are the results:
An informal poll after the election showed that nobody preferred older voting services, although half were indifferent.
More to the point, almost everyone preferred the new voting method. Two had no preference, and only one preferred Approval (which most PSF-related elections still use).
The newer method is called STAR, Score Then Automatic Runoff. Each ballot gives each candidate from 0 through 5 stars. The two candidates with the highest total number of stars proceed to a runoff phase: whichever of the two is preferred on more ballots is the winner. A is preferred to B on a ballot just means the ballot gave more stars to A than to B. The magnitude of the difference doesn’t matter. 2 to 1 is just as much “a preference” as 5 to 0.
For a multi-winner election, put the winner aside, and repeat the process with the candidates remaining. You don’t need to vote again. You cast one ballot at the start and you’re done.
There’s nothing wrong with Approval. It’s a fine method! And it will usually deliver the same winners as STAR. In large-scale voting simulations, STAR does somewhat better, but that’s not the primary point here.
The point is that people like being able to express more of what they believe, and particularly to express that they like A “a lot more” than B, or “just a little more”, or that they have no preference between them (if so, give them the same number of stars). The happier people are with their voting experience, the more likely they are to vote, and that matters too.
STAR is more involved than Approval, but not much so. Approval is basically a “0 or 1 star” method Every part of STAR is simple, and easy to understand.
STAR is a highly regarded (by voting theory experts) method, and - a story for another day - encourages honest ballots in several ways. Games people play to try to “outwit” purely scored (“cardinal”) or purely preference (“ordinal”) methods are as likely as not to backfire under STAR, because it incorporates aspects of both cardinal and ordinal methods. Each tends to counteract the weaknesses of the other.
STAR’s leading advocacy group is “The Equal Vote Coalition”, which has a world of info about the method:
It’s refreshingly non-hysterical for an advocacy site, though. They play fair, and - yup! - they like Approval too. They just like STAR better.
I’d like to see the PSF move to STAR for Board elections too. How about you?
Hoppy to answer any questions I can. But tagging @ArendPeter, who is an expert on both the method and the voting service. Arend is the best source for definitive answers.
