There were so many times in graduate school (when I was younger, more idealistic, and far less jaded) when I thought 'oh, my colleagues just have it wrong' or 'I can't wait to see how this new evidence opens their mind' only to see grad students and ostensibly smart PhDs twist themselves in mental knots to justify their psychosis.

I left graduate school in such despair, because you can't reason with these people. They're not being led by a 'cabal' or anything -- they're just stuck in the same sort of faulty logic/hubris that humans have succumbed to time and time again.
