By the way, Stack Exchange (which is not a prediction market, but still a mechanism that tracks reputation for people who give good answers) tracks the score separately per area of expertise, so e.g. correctly answering 100 questions on software development will not make you an expert on parenting, and vice versa. So this a possible approach to check for people who are “experts in X, crackpots in Y”.
Which again is not perfect, for example correctly answering 100 question on Java will automatically make you an expert on PHP. Perhaps the area of expertise could be defined more fluently, e.g. using tags, and displaying how much the person is an expert on given tags. (Which again raises a question of how the tags are assigned, especially if assigning the tag is part of the controversy...)
But yes, even “farming karma at X, burning it at Y” is preferable to current system that is without any tracking whatsoever (except for maybe “this person has a diploma” or “this person works for a newspaper” which gives them unlimited karma to burn).
Yes.
