Thanks for the comments regarding Arrow's theorem. It helped hash some
things out in the discussion section of wikipedia, and I ended up able
to get a more modified objection of the *usage* of Arrow's theorem back
in the wiki page. Here it is:
http://en.wikipedia.org/wiki/Arrow%27s_impossibility_theorem
Of note, the previous summary definition of Arrow's theorem was:
"In voting systems, "Arrow's impossibility theorem", or "Arrow's
paradox" demonstrates the impossibility of designing a set of rules for
social decision making that would obey every "reasonable" criterion
required by society."
The new summary definition on the wiki page is:
"In voting systems, "Arrow's impossibility theorem", or "Arrow's
paradox" demonstrates the impossibility of designing a set of rules for
social decision making that would pass all the criteria collected by
Arrow in the theorem. The theorem is frequently misrepresented as a
proof that a reasonable voting method is impossible."
More is added in a discussion section.
