I would probably say that we can define honesty for ranked ballots and 
for von Neumann-Morgenstern utilities, but anything beyond that and it 
gets really hard. And if we can't define honesty, then methods can get 
away with externalizing their burden on the voters the way Range does.

As for different strength prefereces, it feels kind of like "neither 
this nor that". I'd rather have an automatically normalized rated ballot 
(if utilities are important) or MJ-style grades or plain rankings (if not).

(Personally, I'd imagine what voters can reliably answer lies somewhere 
between rankings and vNM utilities. Just where, I don't know, though.)
