The human brain is an incredible marvel of evolution. But what's even more incredible is how this supercomputer in your head is able to occasionally make such dumb mistakes.
Pop quiz, hot shot! What do cows drink? If you're like the vast majority of people, you probably just had the word "milk" flash in your brain. That's natural, as 'cow' plus 'drink' to most people equals 'milk'. But that's your automatic system talking, and that, as neuroscientist Dean Buonomano points out, is usually the part of the brain that makes most of the bonehead decisions in life like forgetting people's names and missing easy math problems. The reflective system, on the other hand, is the more logical and computational part of the brain. It takes a little longer to arrive at the answer but that's because it's doing a much deeper dive than your other system. It's a fascinating topic, and Dean explains it perfectly. And if you're still wondering what the answer to the pop quiz was, your reflective system should've told you that cows drink water. Dean Buonomano's new book is Your Brain is a Time Machine.
One day in 1995, a large, heavy middle-aged man robbed two Pittsburgh banks in broad daylight. He didn't wear a mask or any sort of disguise. And he smiled at surveillance cameras before walking out of each bank. Later that night, police arrested a surprised McArthur Wheeler. When they showed him the surveillance tapes, Wheeler stared in disbelief. 'But I wore the juice,' he mumbled. Apparently, Wheeler thought that rubbing lemon juice on his skin would render him invisible to videotape cameras. After all, lemon juice is used as invisible ink so, as long as he didn't come near a heat source, he should have been completely invisible.
