I don't mean to just be a pedant when I say this, but the use of the word crackpot is missplaced here. Crackpot theories are eccentric and not commonly believed. I am interested in crackpot theories because sometimes they end up turning out right, and I think within that dynamic there are important lessons for humanity that we end up learning in very hard ways. For example, the Great Depression paved the way for the acceptance of Keynesian economics--ideas previously written-off as crackpot theories. Another: NASA engineers warned of the exact dangers of a foam strike, under the exact conditions in which it took place, were at the time written-off by senior management. Social scientists that studied this described part of the problem as Groupthink.
