[EM] Arrow's Theorem

[Jobst Heitzig]

Dear Stephen,

> "democratic" implies majority rule

This is by no means clear. You might want to consult this list's
archives to find some discussion of this.

My opinion is rather that "democracy" and "majority rule" are
incompatible since the latter assigns all power to 50%+epsilon in the
worst case, allowing a mere majority to oppress all other voters.
Democratic group decisions rather require some amount of chance to give
all voters a fair share of the power. There is an article on this by
Forest and me in Soc Choice Welf
