Look at the last sheet. If your browser has trouble with the
formatting, there is a simple page at
http://www.beyondpolitics.org/OptimalRangeVote_files/sheet006.htm
That page and the previous tab, sheet005, are reformatted for
clarity, the other pages are my original 2-voter study and the first
arrangement of the many-voter study.
The election is many voters, so many that three-way ties can be
neglected. The study looks only at conditions where the voter's vote
can affect the outcome; conditions other than these cannot affect the
voter's relative utilities for choices which *can* affect the
outcome. (The utility for all those other conditions is 1.0 in this election.)
This election is a counterexample to the claim that optimal voting in
Range is never the sincere vote.
The election is many voters, Range 2 (3 Cardinal Ratings), three
candidates, zero knowledge.
The voter has utilities of 2, 1, 0.
The *relative* utility for voting sincerely is 40/27, for voting
Approval Style, either 220 or 200, it is 39/27.
Numerous writers have informed me that this is impossible, but have
given me theoretical arguments which do not address the conditions of
this study. Most notably, this is a Range 2 election, and it is
totally zero knowledge, and the utilities are exactly balanced for
the middle candidate.
