[EM] Re: Falsification & "completion"

[Kevin Venzke]

Mike,

I don't understand what prompted you to write such a puzzlingly irritated 
reply.  If I said something that offended you, do tell.

If you are angry that I didn't reply to your message showing that MMPO does 
have truncation incentive, I'll get that out of the way right now:

Mike seems to be right about MMPO and truncation incentive.

It sounds like you think I was arguing against you, but I was only trying
to be helpful.  Chris thought it was, but that doesn't mean I'm on anyone's
side.

Good points here, and you refrain from criticizing me.

I didn't say I believed that.  Here you are doing the same thing you just
scolded me for.

Here you do it again.  If I had said that apparently YOU hadn't been paying
attention to something, you would have given me hell for it.

I've been posting on this list since February.  I don't know why you think
I must not have paid attention to the Condorcet discussion.

I never advocated Symmetric-Completion or Margins.  You make that error
throughout your reply.  I can discuss something without advocating it,
can't I?

What Woodall or I consider important hasn't even been discussed.  You couldn't
back up that last sentence even if I asked you to.

I don't think I asked this.  It is a good answer, though.

I believe I asked, roughly, why it provides flawed results.  You can show
that it has bad effects with pairwise methods, but I remain interested in
finding a more general answer.

I'm glad you can agree that it sounds desirable.  I think so, too.  I
don't think it's attainable, though, as I think it requires Strong FBC.

Again with the condescending tone!

That's correct, as long as "should" means "according to the Symmetric-
Completion criterion."


I haven't replied to a lot of what you wrote, because I already agreed
with it.
