What is the justification for Bayesian Regret, as used in IEVS and
described at http://rangevoting.org/BayRegDum.html, being the
"uniquely right" metric, the "gold standard", for comparing different
election methods or varying election scenarios?
Why is the societal utility for a candidate the sum of the voters'
individual utilities for that candidate? How does that avoid the
problems of being arbitrary or not well-defined, when making
interpersonal comparisons or summations of von Neumann-Morgenstern
utilities? What is Bayesian about the resulting value, which is just
a difference in utility values?
