We feel a deep pleasure from realizing that we believe something in common with our friends, and different from most people. We feel an even deeper pleasure letting everyone know of this fact. This feeling is EVIL. Learn to see it in yourself, and then learn to be horrified by how thoroughly it can poison your mind. Yes evidence may at times force you to disagree with a majority, and your friends may have correlated exposure to that evidence, but take no pleasure when you and your associates disagree with others; that is the road to rationality ruin.
Besides him telling me that one of my secret pleasures is "EVIL," Hanson's post disturbed me because I think it is totally wrong. Isn't the whole point of John Stuart Mill's On Liberty that we should nurture dissent, so as not to become slaves to our own prejudices? I go out of my way to disagree when there is a "consensus" on something, and I think that serves a useful purpose besides relieving me of the chore of maintaining a bunch of friendships.
