So many people thought they were in full control of their actions, but much of human behavior was hardwired through evolution. People couldn’t change it if they wanted to. “If a man is walking through the forest and he hears a noise . . . if he assumes it’s a tiger and runs away, he’s more likely to survive than the man who hears a noise and guesses it could be anything. The man who survives has kids who have the gene to be suspicious of random noises and make connections even if they don’t exist.”
