I don't agree that copying the thread-title makes the most useful subject
line. If I entitled this "Re: approval doesn't meaningfully meet Majority or
Mutual Majority", that wouldn't tell which posting by that name I'm replying
[This is a slightly improved version of the posting that I made 50 minutes
Good, that's good that you're improving your postings. But I suggest that
you should improve them more before posting them.
I am not making errors
You have been making errors. Lots of errors.
Your posting that I'm replying to now might not have the simplest kind of
factual errors that your previous ones had, but it still has incorrect
Main point: The way you word your PMC definition is not meaningful.
That's your main point? Your main point doesn't make any sense. In what way,
for what reason, do you think that the wording of PMC isn't meaningful? Do
you know what meaningful means? True to form, you repeat that statement
throughout your posting, without at any time telling why you don't think
that wording is meaningful. Instead of lreplying to each repetition of that
statement in your posting, I've replied to it in this paragraph.
should word it more like your MMC and CC definitions.
Again, you apparently forgot to tell us why I should word PMC like MMC and
CC. PMC isn't MMC or CC, and so unless you can suggest a reason, there's no
particular reason why it should be worded like them. You repeat that
statement too, in throughout your posting, and there's no need to reply to
each repetition, and so this paragraph is my reply to it.
But I'll comment some. You keep saying that, to be meaningful, PMC should be
worded like MMC and CC. My CC, MMC, and PMC were all written as they were in
order to comply with the intent of the original criteria that they're
versions of. None of those criteria is original with me.
So that's why I word them as I do. Predictably there are differences in how
they're worded, because they're intended to comply with the original intent
of different criteria.
The other Condorcet versions were around for a long trime before I wrote
mine, and so was the traditional votes-only MC. MMC is based on a criterion
that Bruce Anderson proposed in the early 90s, and my MMC is intended to
comply with the intent of Bruce's criterion.
You post "CC" and "MMC" versions that are worded more like PMC. But those
criteria can't accurately be called "CC" or "MMC", because that wording
change makes them too dilfferent from the intent of their original versions.
You say that your modified versions aren't meaningful. Yes they're
meaningful. They just aren't what I've sought to test for, and they just
don't bear any resemblence to the criteria whose names you give to them.
In a previous posting you said that preference criteria should stipulate
that everyone votes sincerely. I thought that was just a careless statement,
but apparently you believe it. As you said, preference criteria must
stipulate how voting is constrained by preferences. But who says that there
must just be one such constraint, for all preference criteria?
And, by the way, your comparison would be more meaningful (if I may borrow a
word from you) if you compared PMC to SFC and GSFC instead of to CC. CC
speaks of everyone voting sincerely, but PMC (like SFC & GSFC) speaks only
of members of the referrred-to majorilty voting sincerely.
SFC and GSFC are intended to require a lot from a method. MC is one of the
weakest and most easily-met criteria. They're opposite in that regard.
Therefore it's odd that you think that PMC should share the voting
stipulations of SFC & GSFC.
Note: In this posting I will refer to your MMC and CC definitions as PMMC
and PCC, because they are preference criteria.
Then do you refer to the other CC versions as NRMEECC
(Nonrank-Methods--Explicitly-Excluded Condorcet Criterion, because it
explicitly doensn't apply to nonrank methods) or NRMEFCC (Nonrank
methods-Explicitly-Fail Criterion, because it explicitly says that nonrank
methods fail it)? Or PPCC (Plurality-Passes Condorcet Criterion, because
Plurality passes it)?
Actually there's no need for saying PCC and PMMC, because preference CC and
preference MMC accord with the original intent of those criteria. The
difference, from NRMEECC and NRMEFCC is that my CC seamlessly applies to all
methods, with no mention of methods' rules (including balloting rules).
Summary: Points 2 and 3 lend support to the argument that your wording of
PMC is not a meaningful one
No. They don't. You don't at any time tell why you don't think that PMC's
wording isn't meaningful.
, i.e. not in accord with the intent of the
You don't at any time justify that claim. Where PMC differs from FHC is when
FHC says that Plurality passes and Approval fails, due to something that no
one could seriously call an advantage of Plurality over Approval. PMC
differs from FHC when FHC malfunctions. If you propose FHC, you're the last
person who should be using the word "meaningful".
Take your PMMC definition, your PCC definition, and your current PMC
definition. It's kind of like Sesame Street:
"One of these things is not like the others / One of these things just
doesn't belong / Can you tell which thing is not like the others / By the
time I finish my song?"
The one that doesn't belong is your current PMC definition.
It's good that you've learned something from Sesame Street. But you've
missed their point. They were merely trying to teach you that things can be
different some particular way even if they might be similar in other ways.
They weren't trying to teach you that things should be the same. Things are
often different. That's why we call them different things, instead of the
same thing. You've failed to understand what Sesame Street was trying to
Say you were presented with a pancake, a square cloth pot-holder, and your
brother. Which one of those things is most different from the others? Which
of those three things "doesn't belong"? By your reasoning, you'd believe
that it's somehow incorrect for your brother to be different from those
other two things, and so you'd want to make your brother more like those
other two things, by making your brother flat and not alive.
But you don't have to do that. It's ok for things to be different from
eachother. It's alright.
I take the voting systems topic seriously, and so I reply conscientiously to
people, even to you. But you don't. You're using EM as a role-playing
playground. If you want to play the role, without doing the work (the work
of verifying what you say), then I suggest that you take a drama class
