"Double Defeat, Hare" poll candidate

CB

Tue, Apr 16, 2024 2:48 PM

I would like to nominate  Double Defeat, Hare.

*Voters strictly rank from the top however many candidates they wish and
also may specify an approval cutoff.

Default approval is only goes to top-ranked candidates.

All candidates that are pairwise beaten by a more approved candidate are
disqualified.

If that leaves more than one qualified (i.e. not disqualified)
candidate, commence eliminations according to Hare
rules until only one qualified candidate remains.*

This is a compromise between Hare and Condorcet which will probably not
please the fundamentalist supporters of either,
because it doesn't meet the Condorcet criterion and is more complicated
than Hare and fails Later-no-Harm and Later-no-Help.

But it addresses the concern some have about electing a weak low social
utility Condorcet winner, and I think it might simulate
well.

I think that methods that allow voters to both rank the candidates and
specify an approval threshold/cutoff
should never elect a candidate that is pairwise beaten by a more
approved candidate.

I coined this criterion as "Double Defeat" and it occurred to me that it
could be a disqualification device that
is part of a method.

Some people are wary of Condorcet electing a "weak centrist" candidate,
for example

49 A>>>C>B
48 B>>>C>A
03 C>A>>>B

Assuming all voters get the same utility from electing their favourites,
the Hare (and FPP and presumably Approval)
winner is the highest Social Utility candidate A.

With those sincere preferences, the ranking-with-specified-approval
ballots would be

49 A|>C
48 B|>C
03 C>A|

Here the Double Defeat rule doesn't interfere with Hare.  B is
disqualified because B is pairwise beaten by the more approved A.

So then, following Hare rules C is eliminated leaving A as the only
qualified candidate and so winner.

The C>A voters have no real complaint other than "The method should meet
the Condorcet criterion" and any complaint from
the B>C voters is answered by "To get a result you prefer you didn't
have to order-reverse, you could have had A disqualified by
approving C".

The method is similar in spirit to an "Approval-enhanced Hare" that
arose from discussion I had here a few months ago with Forest,
but which I forgot about and didn't rediscover until after nominations
for the poll had closed:

Elect the most approved member of the set comprising the Hare winner
and all the candidates with a beat-path to the Hare winner.

49 A (sincere might be A>B)
24 B (sincere might be B>C)
27 C>B

A classic example that has been interpreted as Hare and Margins by
electing A failing Minimal Defense and avoidably causing the C voters to
regret
not Compromising, and alternatively by electing B the C>B voters having
been taken advantage of by the B voters using a Defection strategy, a
failure
of the Chicken Dilemma criterion.

In this example it is true that in all the methods that meet Double
Defeat it is up to the C>B voters to decide which is more important for
them:
preventing the election of their greater evil A, or preventing being
taken advantage of by Defecting B voters.

It's still happening, I think Mike just didn't want anything to do with
it. I'll gather up the poll posts and run them through Schulze (for the
ranked ballots) and Approval (for the approval ballots) once the period
is up.

That reminds me: I should make a post showing the subject of the poll,
per Mike's first post, and the deadline. If I can just get enough time
from the things claiming my attention at the moment.

It's still happening, I think Mike just didn't want anything to do with
it. I'll gather up the poll posts and run them through Schulze (for the
ranked ballots) and Approval (for the approval ballots) once the period
is up.

I appreciate it. …that the poll is being administered effectively. Sorry
again about losing my temper..

I was discouraged when It seemed like Garman’s & Robert’s
contrarinesses-for-its own-sake was the state-of affairs.

I just feel that Schulze has much long-established support.

I still want my ballot counted, but with Smith//Approval(implicit) added
directly above Schulze, due to its better simplicity & proposability.

I’ll re-send my ballot with that revision.

…& thanks for mentioning the initial motivating-question of finding out
what members like for public-political-elections.

That reminds me: I should make a post showing the subject of the poll,
per Mike's first post, and the deadline. If I can just get enough time
from the things claiming my attention at the moment.
