Intelligence doesn’t protect you from believing wrong things. It makes you better at believing them.
Smart people are excellent at finding reasons for what they already want to believe. They can construct elaborate arguments. They can spot flaws in opposing views. They can make almost anything sound reasonable.
This is motivated reasoning. Your brain decides what it wants to be true, then your intelligence gets to work building a case.
I see this everywhere. The brilliant professor who thinks vaccines cause autism. The sharp lawyer convinced the election was stolen. The physicist who believes in homeopathy.
They’re not stupid. They’re using their intelligence in service of their conclusions, not their evidence.
The smarter you are, the more sophisticated your rationalizations become. You can find studies that support your view. You can identify methodological problems in studies that don’t. You can build theories that explain away inconvenient facts.
Regular people might believe something because they heard it on TV. Smart people believe it because they’ve constructed a twenty-page argument for why everyone else is wrong.
The antidote isn’t more intelligence. It’s intellectual humility. The willingness to be wrong. The habit of looking for evidence that contradicts what you want to believe.
But that’s hard. It means admitting your smart brain led you astray. It means losing arguments you’ve already invested in.
Most people — smart or not — would rather be wrong and confident than right and uncertain.
