I'd say that these voters can't even determine what the mean *is*. The mean is based on utility estimates, which are made on the assumption that a candidate's estimated utility corresponds to the voter's happiness with the result when this candidate is elected. If the voter can't estimate this independently, he has to use a different strategy. > Given a free chance, would you rather have a fifty percent chance of > winning a million dollars or a one percent chance of winning sixty > million dollars? > > Your answer tends to depend on whether or not you are already a > millionaire. This would affect the utilities of the choices. What you should ask instead is "Given X free chances, would you rather have a fifty-percent chance of 0.17 utility or a one-percent chance of 10 utility?" The default prize is 0 utility. You should assume that the special value (if any) of having some utility rather than no utility has already been accounted for. Otherwise, I don't see what the 0.17 and 10 figures would be based on, or even what this question is asking.
