As you know, I’ve been a lot more favorable to Hare than most. But:
1. I’ve realized that the choices, sometimes strategic, that Approval puts
on the voter are a lot better than the count-complexity &
computation-intensiveness—& consequent count-insecurity & count-fraud
vulnerability of the ranked methods such as Condorcet & Hare.
That count-fraud problem is the worst, but, overall, Approval is much
easier to introduce, describe, explain, propose—& much easier & inexpensive
to implement (can be implemented at zero cost, without even
software-modification), administer & audit against error &
count-fraud…compared to any other multicandidate-suitable method.
…especially the ranked-methods.
I’d much rather trust voters to use Approval well than trust that the
count/m-staff won’t be bribed to do fraud.
Approval is the absolutely minimal method that allows & counts
multicandidate comparison…& therefore the unique completely unarbitrary
method.
Score & STAR? They have a strategy-problem that Approval doesn’t have, when
some people vote sincerely (merit-proportionate) & others vote
strategically (all-or-nothing).
But I nonetheless would rather have that than the problems of the
rank-methods.
Likewise, Score & STAR are less simple than the absolutely minimal
Approval, & so I much prefer Approval. …but Score & STAR don’t even come
close to the computational complexity of Condorcet & Hare.
I prefer Score(0-5) to STAR because of the strategy-complications &
problems of the runoff, & the resulting FBC failure that you pointed out.
But, for public political elections, STAR still beats Condorcet & Hare, due
to their count-complexity.
2. Hare, while sharing the count-complexity of Condorcet (& additionally
requiring either one big central count, or lots of back-&-forth information
transfer between precincts & Central) doesn’t share Condorcet’s
strategy-freeness…requiring a favorite-burying top-end defensive-strategy
to protect acceptables from unacceptables. …with the risk that timid
lesser-evil voters will do the same to protect their lesser evil.
Sure, Hare elects the favorite of the largest faction of the
mutual-majority when there is one, but the support isn’t always mutual.
You can hope that, with Compromise as your 2nd-choice, if Favorite
eliminates Compromise, Compromise’s voters will transfer to Favorite
because they’re both progressives. But, for one thing, if Compromise’s
voters transfer the other way, an unacceptable could be elected. That’s too
big a chance to take when there are completely unacceptable candidates.
For another thing, if they transfer to a perceived progressive, it might
not be Favorite, & might not even be very (or at-all) progressive.
I used to think that Hare was alright for polls, but Hare can have its
problem & do a funny trick, do a Silly, even in a poll. It demonstrated
that in a Free-&-Equal poll.
But I like Hare for choosing a pizza 🍕 topping or a 🍿 etc.
Easy handcount too.
I prefer Condorcet, especially RP(wv), for polls, & to propose to
jurisdictions where people insist on rankings. But not for public political
elections, for the abovestated reasons.
