A lot of very smart people believe some very stupid things. Why? 

“While unintelligent people are more easily misled by other people, intelligent people are more easily misled by themselves. (Intelligent people) are better at convincing themselves of things they want to believe rather than things that are actually true. This is why intelligent people tend to have stronger ideological biases; being better at reasoning makes them better at rationalizing.” – Gurwinder
