Why do you think the Bloodletters set back science? As if there was anybody at that time that would have made more rapid progress if only they hadn't been held back. Science isn't a strait line of analytical progression, and when it does get side tracked, it isn't some nefarious group. I could just as easily say if only those stupid String Theorist had just stepped aside, we wouldn't have set Physics back a decade. It's human dynamics, hmmm, I wonder if there is someone studying why groups get stuck in these loops, hmmm, why do humans seem to get stuck at a plateau that is difficult to think beyond, hmmmm let me think now, hmmm. Psychologist?
