Even many of the smartest people that have ever lived convinced themselves of false things (just like the rest of us). Here are some fun and wild examples:
(1) Linus Pauling won TWO Nobel prizes – one in peace and one in chemistry. Unfortunately, he eventually became obsessed with and widely promoted the false (and sometimes still repeated) idea that high-dose vitamin C cures many diseases, including HIV and snakebites.
(2) Isaac Newton, who co-invented calculus and discovered the laws of gravity, also was convinced the Bible had hidden messages he could decode for prophetic purposes, and spent a lot of time trying to create the mythical philosopher’s stone, so he could turn metal into gold.
(3) Alan Turing, often considered to be the father of theoretical computer science and artificial intelligence, seemingly was convinced by the existence of extrasensory perception. He wrote: “the statistical evidence, at least for telepathy, is overwhelming.”
(4) C. Langan, who appears to have one of the highest IQs ever recorded, believes “you can prove the existence of God, the soul, and an afterlife, using mathematics.” and has claimed that 9/11 was an inside job staged by the Bush administration.
My point is not that these people were stupid – they are the opposite of stupid – they are far smarter than 99.9% of the people that have ever lived (by at least some reasonably common ways of thinking about intelligence). My point is that even the smartest among us hold some silly, false beliefs – intelligence is not enough to avoid error.
Rationality (in the sense of evaluating evidence in such a way as to effectively arrive at the truth on important topics) and intelligence, while related, are also not the same things. Rationality involves actively working to disprove your own beliefs – which intelligent people may or may not do. For instance, intelligence is often used to come up with clever and convincing arguments for why what you already think must indeed be correct. In other words, intelligence can be deployed for rationality but also for rationalization.
Of course, it may also be me that’s wrong. Perhaps there’s a philosopher’s stone, vitamin C cures a ton of diseases, 9/11 was an inside job. But more likely, I’m wrong about other things (that I have no clue I’m wrong about). It’s useful to remember: we all believe false things.
