First of all, the original statement was general, and so Smith simply 
gave a simple counterexample from a small election, a common practice 
on this list. Ossipoff does it himself. But now he specifies his 
statement more narrowly, and Smith's example, therefore, no longer 
applies -- if I remembered it correctly.

I've given a case, fully specified. How many times to I have to 
repeat it. Many voters. Zero knowledge, which means that all the 
probabilities are exactly equal. Three candidates, Range 2, our voter 
has utilities of 2,1,0.

Optimal voting strategy: Sincere. Expected utility of Sincere: 40/27, 
of Approval, 39/27. Not voting: 1.0.

With a counterexample, we do not worry about consensus, do we? The 
emperor has no clothes.
