Ben Carson’s ideas about things like the pyramids, combined with what he has said about other more immediate topics, suggest not only that his beliefs are impervious to evidence but also an alarming lack of what we might call epistemological modesty. It isn’t what he doesn’t know that’s the problem, it’s what he doesn’t realize that he doesn’t know. He thinks that all the archeologists who have examined the pyramids just don’t know what they’re talking about, because Joseph had to put all that grain somewhere. He thinks that after reading something about the second law of thermodynamics, he knows more about the solar system than the world’s physicists do. He thinks that after hearing a Glenn Beck rant about the evils of Islam, he knows as much about a 1,400-year-old religion as any theologian and can confidently say why no Muslim who doesn’t renounce his faith could be president.
So what happens when President Carson gets what he thinks is a great idea, and a bunch of “experts” tell him it would actually be a disaster? What’s he going to do?
He’s kind of an extreme case, but the problem is fairly widespread at the moment. It’s pretty rare these days to hear someone say the words, “I don’t know.”
