It seems that in most real life examples of range voting, they are in a niche field where either:
There are objective measurable criteria for how to determine ranges (physical distance, time distance), or
Complicated scoring system that at least pretends to be objective via complicated scoring rules.
How do the proponents of range voting propose to deal with the complication of "what does 0-10 mean objectively" for political applications of range voting, where the scoring criteria is basically a fully subjective "like-dislike" or "approve-disapprove" continuum?
