I said that Plurality only lets you rate one candidate. That isn't
true. You're still rating all of the
candidates in Plurality, but you're required to bottom-rate all but
one of them.
Looking ahead, Plurality lets the voter present a small amount of
information; Approval a bit more; and Condorcet additional - each such
as the previous methods do not permit.
So Plurality doesn't have a _lack_ of information. It has forced
falsification of informtion.
It should be pretty obvious that that can't be desirable. And it
shouldn't be surprising, the
adverse societal consequences of it.
Approval is such a simple, minimal change that there can be no
question that Approval is
an improvement on Plurality, and only an improvement.
Agreed that Approval allows approving more than one, and that each
approved is preferred over each unapproved, just as the one approved
in Plurality is preferred over all others.
That can't be said for Condorcet or Kemeny, or any other rank method
or complex method.
Now it is time to be more careful.
In Condorcet if I give one rank to all I prefer I have given the same
preference to those ranked over those unranked as I could do with
Approval's approving.
But ability to use multiple ranks in Condorcet or Kemeny gives me
additional power - among the ranked candidates my preferences can be
unequal and I show this by ranking higher each that I prefer over
other ranked candidates.
Condorcet perhaps should be described as a family of election methods,
usually agreeing as to details such as winner chosen - such as Kemeny.
I don't know anything about Kemeny's properties, and I was just
asking what it does with the
2nd set of rankings in my previous posting, and whether or not it
passes FBC. I don't claim to
know Kemeny's properties.
"2nd set" implies misunderstanding - in the Condorcet family voters
are normally permitted to use more than two rank values.
"FBC" is simply one of many acronyms for which definitions are hard to
find (and to verify having found correctly).
Ask some people, some members of the public, what they think of
various proposed methods.
