Unfortunately, there are certain area of science where there are unexamined biases. Stray too close to there, and they are automatically dismissed as crackpot.<p>In science, evidence trumps eminence, unless it is something like cold fusion.<p>If we can measure this &quot;crackpot bias&quot;, I am not sure psychedelic research would have as high of a bias as cold fusion, but it might have been closer say, ten or twenty years ago. No one wanted to touch that stuff or could get grants to do such research.
