A counterpoint is the “door-in-the-face” experience, where the guilt you feel about denying a request-such as loaning bus fare-leads you to acquiesce in other ways-like picking up the beer tab-as a means of making it up. You might first be willing to lend a friend bus fare, and next to pay for drinks at the pub, and finally you’ll take care of the cab ride home. There’s the “foot-in-the-door” technique, “where agreeing with a small request will make you more amenable to a larger request,” says Burnett. Two phenomena demonstrate this perfectly. All of our brains are easily manipulated. But one of the most fascinating revelations Burnett makes has to do with the extent to which the brain can be manipulated because of our desire to please others. As Burnett puts it, “Who needs predators when we have our expanded craniums to drag us down with persistent stress?”Ĥ. These things matter to our big, lumpy brains.” In this sense, humans have hardly evolved despite surviving the era when we were perpetually stalked by toothy beasts looking for their next meal. “The threat of not being liked poses no physical danger,” says Burnett, “but to our mental well-being and our place in the community it’s a proper danger because we could lose our status, support network respect. That desire to be liked? It’s programmed in all of us. We can still be afraid of them because that part of our brain doesn’t discern between real threats and imaginary ones.” The result is a modern plague: rampant anxieties.ģ. “Now we can be afraid of things that are both unharmful in the physical sense and might never happen. As such, “the term ‘threat’ is up for grabs now,” says Burnett, in describing the “smallest tip of the gargantuan neurotic iceberg” of worries taken up by our brain. But few of us live among nature like wild animals anymore.
Your brain is paranoid by design. Humans, like all creatures, have evolved by way of a “primitive threat detection system,” Burnett says. “A sense of self-worth and achievement seems to be integral to normal functioning for humans,” says Burnett. That is to say, insecurity undermines progress.Ģ.
It’s a practical method for us to avoid paralysis. But why? Burnett says given the number of decisions facing us every day, our brain requires an inherent confidence for us to be capable of actually making any choices. In effect, people unknowingly give themselves more credit than they’re due. Your brain thinks you’re better than you are. Early on in the book, Burnett describes the incredible egocentric bias exhibited by the brain as a means of “making you feel and look as good as possible”-to the point of even modifying memories unconsciously. “These things have a massive effect on the world at large because everyone is using the same system to get things done.”ġ. “All these weird habits of the brain affect every single person,” says Burnett. In fact, in some ways, the human brain is rather stupid. In The Idiot Brain: A Neuroscientist Explains What Your Head Is Really Up To, Burnett-who is based at the Institute of Psychological Medicine and Clinical Neurosciences at Cardiff University in Wales-manages to both confirm and disavow the common notion that the human brain is a sophisticated marvel. “It’s like a self-awareness book-not a self-help book.”īurnett has, by way of a joke, invented a new literary genre that he alone appears to occupy, which seems in keeping with his clever approach to writing and science. “The response I was going for was always, ‘Oh, that’s why that happens,’ ” says Burnett. When British neuroscientist and comedian Dean Burnett was asked to write a book about how the brain works, by publishers who were impressed with his popular science blog for the Guardian newspaper, there was one condition: Burnett wouldn’t prescribe solutions for readers to overcome the range of quirks he knew would be uncovered.
