The best books that challenge everything you know about the brain

Lisa Barrett is one of the most respected researchers in psychology today in part because she is unafraid to debunk the comforting misconceptions we have about our minds, and especially about our emotions. Seven and a Half Lessons About the Brain dispels myths about emotion, and about our reptilian brain, among others. One of the most important lessons in the book is that your brain is not for thinking—it is primarily for myriad other processes of maintaining internal organs, blood oxygenation, energy consumption level, balance, and for performing a host of other tasks. But for Barrett, it’s not just about debunking. She has a compelling vision of how the brain actually does work. Not only does she have deep expertise in human behavior, brain anatomy, evolution, and neurochemistry, her vision of how our minds work is also described in energetic prose.

For most of the time that humans have studied the brain, the approach has been to go from the outside to the inside. That is, we probe the brain with “stimuli” from the outside—images, sounds, electric shocks, social scenarios—and see what happens inside. This has led to progress but we need more fundamental understanding about how brains work intrinsically. This is the “inside-out” neuroscience Buzsaki describes: it is about asking about the logic of the internal processes of the brain. Buzsaki is a highly respected researcher who has for decades probed and listened to neurons in the mouse hippocampus. This book, which is both accessible and entertaining, summarizes just a portion of his life’s work, and draws on a staggering amount of knowledge about brain physiology and evolution to paint an entirely new picture of how the brain works. Along the way, all kinds of popular misconceptions such as our “reactive” nature fall by the wayside and are replaced with new and exciting alternatives.

Thanks to Freud, one of the most cherished ideas in psychology is that we have an unconscious. Yet because it is by definition inaccessible, our unconscious is almost impossible to study scientifically. Freud himself certainly didn’t provide much reliable evidence for its existence. Nick Chater, a respected researcher of language and perception, argues that little if any evidence for an unconscious drive exists even now, almost a century after Freud. With lively and pugnacious arguments drawn from fascinating and diverse discoveries about language and perception, Chater deconstructs the unconscious and argues instead for a human mind that is inherently dynamic and in-the-moment. When I have assigned this book to my undergraduate students studying perception it has provoked some of the most heated debates, which is how I know it is a great book!

A popular myth that refuses to die is the idea that the left brain and right brain do quite different things. Chris McManus, a researcher of human perception, as well as a medical doctor, wrote the delightful book Right Hand, Left Hand in part to dispel these myths, but also to explore the wonderous world of laterality. From handedness, to how development builds a symmetrical organism, to asymmetries in subatomic particles, this exuberant book takes you on a grand tour of fascinating ideas and observations, told with the detail, color, and organization of a great symphony. 

No idea in psychology is more attractive than the notion that we have evolved to be super-amazing in terms of certain traits: our logic, mating strategies, food gathering techniques, emotional reactions, are all the best that they can be because evolution settles for nothing less. Daniel Milo, a philosopher of biology, shows instead that evolution almost always settles for “good enough” rather than what is optimal. From the size of our kidneys to our procreative abilities, what matters is what is workable, not what is best. This idea is widely supported, but still unorthodox in evolutionary psychology—and even in parts of evolutionary biology. Breaking out of rigid beliefs that the way things are is the best of all possible worlds is a liberating experience, and one well articulated by Milo.
