Well, now I see what happened. I did *not*
ridicule Venzke. Read it carefully. I said that
Venzke had confirmed the obvious. Since the
obvious sometimes leads to error, it is an
appearance only, confirmation is quite useful. I
was just pointing out that it *was* obvious. I
apologize for the ambiguity in my message that
allowed a tone of ridicule to appear.
Confirming the obvious is a valuable activity, it
keeps us from being stuck in what may even be ancient errors.
Further, while we do have Warren's simulations,
and some theoretical work as well, many don't
trust those, for reasons which must be
frustrating to Warren, since they boil down to
"You've done it wrong," or "You are biased," but
don't point out exact errors, and, in some cases,
the alleged "errors" are only simpifying
assumptions that Warren is explicit about. For
example, it's possible that the utility
distributions Warren uses don't match reality.
However, it is far from clear that this has any
significant effect on what the simulations show.
It's true, Condorcet methods work better in real
elections, we can expect, than we would expect
from, say, random assignments of utilities,
making cycles rarer than they would otherwise be.
However, I think the distributions Warren uses,
which are *not* even random distributions, if I'm
correct, are likely to be reasonable, with more
accurate distributions not significantly shifting
the results. How voter utilities will be
distributed, in real elections, will be a constantly shifting thing.
No more new text below.
