"I think people tend to fool themselves. People think they’re good at what they do, and they don’t question their practices. Because James [Somerton] and [co-writer] Nick both thought they were experts on the topics they talked about, they bumbled into so many blind alleys. I mentioned making this video to my friend Todd and he independently started watching James, and fell down all these rabbit holes, and made a video about him as well. It’s the Dunning-Kruger effect, when you’ve managed to stay at the top of the curve so you think, "I must be an expert", and you never do any work that can disconfirm your hypothesis. It’s scary how easy it is to do that."
