Cranks read their own deeper meanings into simple models. Totally agree that Pr[ person has this characteristic | he is crank ] is high. But lots of “good” researchers do this too. It seems like Pr[ person is crank | has characteristic ] might be low.

Doing research is a social activity. There are important norms. Some people cross these lines in the sand and end up making important discoveries; they get celebrated. Other habitual line steppers make no impact; we call these guys cranks.
