David Brooks's Reading List

"Right. And I started with the easy ones. One very accessible one, but by a guy who is very serious, is a book called The Happiness Hypothesis . It’s by Jonathan Haidt, who is a psychologist at the University of Virginia. Haidt uses the metaphor of a boy and an elephant. He says our minds are structured like a boy riding an elephant, and the boy is the conscious reasoning part, the cortex-based brain. And it can see very far, and make certain steering decisions. But most of the work is done by the elephant, which is the unconscious part of the brain. His work is to try to explain what the elephant is doing. In his research, he focuses especially on moral judgments. So he tells his students the story of a brother and a sister who are off on a trip somewhere. They decide one night they’re going to have sex with each other. They do it, they find it pleasant, and decide they’ll never do it again. But they are glad they did it. And he asks: ‘Is that wrong?’ And most people say it is. But they can’t really explain why they feel that way. He says that feeling of disgust that we experience is a moral feeling that flows unconsciously, it’s not based on conscious reasoning. And he argues that most of our moral decisions are that kind of an instant reaction. It’s like aesthetics: when we see a scene we know instantly if it’s beautiful or not. We know instantly if something feels moral to us or not. I think I would say, and he would say and most scientists would say, that it’s the result of two flows of information. One is the genetic, and in every culture under the sun, incest is regarded as wrong. There is no human culture that really tolerates incest. There’s that sort of knowledge. So we do have some moral knowledge that just comes to us genetically: a sense of fairness, a sense of reciprocity. All humans have these, except psychopaths. So some of that is genetic. But then it’s underlined by cultural things; that’s the second flow of information. And those cultural things may be learned consciously, but are also stored in the elephant."

"This is also a book – like most of the books I have chosen are – on the distinction between subterranean mental processes and conscious processes. And Damasio’s work concerns emotion and the role of emotion in decision-making. We have an idea that every day decisions are shaped by rational thinking, Dr Spock-type logical thinking. But Damasio worked with people who have suffered strokes and as a result are incapable of feeling emotion. And far from making good decisions, they make terrible decisions, and their lives fall apart. His theory, which has now been widely accepted, is called the somatic marker hypothesis. So the basic idea is that emotions is how we value things, it’s our GPS system. When we see something as trivial as an ice-cream cone or as important as a potential spouse, our emotions say we either want that or we don’t, it’s going to lead to pleasure or to pain. And we follow that emotional signal. So the error Descartes made was to separate the mind and the body; the idea that the mind can exist without the visceral emotional reactions of the body. Because you actually can’t have a brain thinking without those visceral reactions. The application for me is that it gives me a new view of how human beings make decisions and operate. We believe that people make decisions based on rational and clear responses to incentives. But in case after case they don’t make decisions that way. And I think most of us understand that the economic model of human nature is not really accurate. And yet all our public policies are based on that model. Economists have tremendous sway over public policy, over foreign affairs. Game theorists impact on our international relations people, they train our public policy figures. And for me, as a result of these books, I just observe and place a lot more emphasis on unconscious decision-making. I’m interested in cultural influences that shape our behaviour in ways that we don’t understand, and even the way that genetics can shape our behaviours in ways that we don’t understand."

"My next book is called Smart World and is by Richard Ogle, who is a private consultant and entrepreneur. And he takes some of these ideas that I’ve been talking about and translates them into the world of business and creativity. And his book is very underappreciated, I think. The other books I’ve chosen are very famous, but this one hasn’t got the attention it deserves. Ogle is a populariser of the work of a philosopher named Andy Clark, who emphasises that ideas don’t just exist in one head, but they exist outside the mind, in a whole bunch of minds at once. And one of the traits of unconscious thinking is that we’re intensely social, we catch ideas and thoughts in ways we’re not consciously aware of from each other. According to Ogle, we’re embedded in what he calls ‘idea-spaces’, what most of us would call culture. So, for example, the simple illustration is Picasso, who existed in one culture, the culture of western art. He came across a separate culture, of African masks, and he really merged these two cultures to create Cubism. The creativity came from these two idea-spaces merging together. Ogle’s book is really about how that happens, ranging from Picasso to the invention of the personal computer."

"Yes, so these are two gigantic books, both very famous, which really should be read by anyone interested in this world. And the first is called The Blank Slate by Steven Pinker and the second is called Consilience by Edward O Wilson. And these books are both landmarks of our time. Yes. Blank Slate is an argument against the old view that there is no such thing as human nature, that we’re all culturally determined. He brings together a ton of evidence that that’s wrong. Some of it involves brain structure, a lot of it involves genetics. He doesn’t really think of it this way, but a lot of it is about the unique qualities that guide behaviour that we’re not aware of. I would say that he is overly reliant on genetic explanations, but it’s still a very important book. Yes, all of these books I’ve chosen are very accessible."

"Wilson makes the argument – or rather the prediction – that a lot of the disciplines we have separated human behaviour into are obsolete, and that we are on the verge of unifying knowledge in an interdisciplinary way. And that’s important because if you look around at various fields, what Wilson predicted a decade ago is actually happening with neuroscience. There’s a field of neural economics, which is a combination of economics and neuroscience, there’s neural this and that, basically neural everything: literary critics, historians. People in many different disciplines are using this work on the brain to illuminate their thinking. And in this way, I think what they’re finding in our unconscious mind will have the same sort of influence that Marx had, and that Sigmund Freud had, namely an entire new vocabulary, that will help define a lot of different fields. Well, except that in the Renaissance we thought we were masters of our destiny, and the whole idea was ‘what a glorious thing man is, with limitless capacities’. But here, each individual is not so special, we are shaped by genes, by social trends; individual decision-making is bounded. There are severe limits on free will."
