That is almost the only thing I did. You didn't ask me to confine myself
to properties that I personally think are *important* or to explain why
I think they are important.

I wasn't criticizing you there. I was merely asking Forest about MAMT.

You replied:
I assume you know what the criterion specifies and are asking me why
meeting Later-no-Help is a good thing.
[endquote]
You assume wrong. I meant what I said. Re-read the last two paragraphs of mine
that you quoted above. If you don't have an answer to it, then that's ok. I
accept that you don't.
No, I'm not asking you about generalities regarding a criterion. I'm asking
specifically who is wronged by the situation that I described.
You continued:
Failing LNHelp while meeting
LHHarm creates a random-fill incentive.
One of the problems with that is
that is unfair to sincere truncators. Why should they be penalised for
declining to play silly games with candidates they don't care about?
Another is that all methods that fail LNHelp are vulnerable to Burial
strategy.

That's what I mean by repetition of generalities such as your criteria,
and such as "unfair to sincere truncators" and "burial strategy", etc.
I asked you specifically about situations with MMT. I asked who is wronged
therein.
I didn't ask for repetition about generalities.
I've told why your criteria, and your terms such as those in the paragraph
before
last, don't describe problems with MMT results and situations.

It is a weakened version of Smith that is compatible with LNHelp
compliance (and so Burial Invulnerability) and also compliance with
LNHarm. It says that that if there is a subset S of candidates that on
more than a third of the ballots are voted strictly above all the
outside-S candidates and all the S candidates pairwise-beat all the
outside-S candidates then the winner must come from S.
From your recent past statements I know I don't have to sell the
desirability of compliance with this to you. I gave this example:
49: A
48: B
03: C>B
I can't take seriously any method that doesn't elect B here. Can you?
Isn't this just the sort of small (probably wing) "spoiler" scenario
that motivates many to support electoral reform?
[endquote]
B pairwise beats A, and is CW. Condorcet's Criterion is incompatible
with FBC. Various different FBC-complying methods, and especially FBC/ABE
methods, will fail CC in various ways, some CC failures being bigger than
others--a matter of degree. But they all fail CC. Maybe you're a strict
Condorcetist, and I don't criticize you for that. We needn't all have the
same goals, values and purposes.
In your example, there's something favoring A and there's something favoting B.
A is better in 1st choice ratings. B has more (1st place + 2nd place) support.
It's
a toss-up, unless your goal is to elect the pairwise winner and the CW.

Yes, and I obliquely responded to your comment. But to be blunt, if
failure of Mono-add-Plump isn't self-evidently *completely ridiculous*
(and so much so that anything not compatible with Mono-add-Plump
compliance is thereby made a complete nonsense of), then I have no idea
what is.
[endquote]
Not good enough. I asked you specifically what is wrong with situations and
results that I described for MMT.
Angry noises may serve to vent your anger, but they don't answer my question.
Could it be that you're evading my questions about what is wrong, unfair
or surprising about the MMT situations and results that I asked you about?
You continued:
This doesn't come anywhere near cutting it:

Is it "surprising or unfair" that some new voters should in effect have
their ballots given negative weight because they refused to play silly
games with some candidates they weren't interested in and maybe knew
nothing about?
Err....*yes*.
[endquote]
Err...You mean "silly games like mutual majority coalition support? :-)
If they think that is silly, then they certainly have the right to decline it...
and then not benefit from it.
