Yvain's blog: Epistemic learned helplessness.
A friend in business recently complained about his hiring pool, saying that he couldn't find people with the basic skill of believing arguments. That is, if you have a valid argument for something, then you should accept the conclusion. Even if the conclusion is unpopular, or inconvenient, or you don't like it. He told me a good portion of the point of CfAR was to either find or create people who would believe something after it had been proven to them.
And I nodded my head, because it sounded reasonable enough, and it wasn't until a few hours later that I thought about it again and went "Wait, no, that would be the worst idea ever."
I don't think I'm overselling myself too much to expect that I could argue circles around the average high school dropout. Like I mean that on almost any topic, given almost any position, I could totally demolish her and make her look like an idiot. Reduce her to some form of "Look, everything you say fits together and I can't explain why you're wrong, I just know you are!" Or, more plausibly, "Shut up I don't want to talk about this!"
If the arguments for orthodoxy are stronger, then you dismiss contrarians entirely: they are obviously wrong! So do other people, so you don't get to hear about them to begin with. And so do most potential contrarians themselves.
So by selection effect, we mostly see contrarian arguments which at least appear to be better than the orthodoxy.
