For a copy of the proof (Warning: turgid): <A HREF="http://socrates.berkeley.edu/~sgoldman/201a/arrow.pdf">http://socrates.berkeley.edu/~sgoldman/201a/arrow.pdf</A> Some good discussion of the basic concepts with easily understood examples and demonstrations can be found at: <A HREF="http://www.gate.net/~svaughen/apportion/p1.html">http://www.gate.net/~svaughen/apportion/p1.html</A> <A HREF="http://www.gate.net/~svaughen/apportion/p2.html">http://www.gate.net/~svaughen/apportion/p2.html</A> We're all familiar with the Black Rose logs (see the archives if you're not (Note: Yes, I just found out that the archives were not updating nightly (cron died) they will all update tonight, MUD-Dev is current now)) and its attempt at governance thru concensus. Arrow's theorem makes the Black Rose incident especially interesting as it now becomes a progressively normed voting system where the number of choices never descend below three.
