This groundbreaking book, a Pulitzer Prize finalist and "New York Times" notable pick, rattled the psychological establishment when it was first published in 1998 by claiming that parents have little impact on their children's development. In this tenth anniversary edition of "The Nurture Assumption," Judith Harris has updated material throughout and provided a fresh introduction. Combining insights from psychology, sociology, anthropology, primatology, and evolutionary biology, she explains how and why the tendency of children to take cues from their peers works to their evolutionary advantage. This electrifying book explodes many of our unquestioned beliefs about children and parents and gives us a radically new view of childhood.

A NEW YORK TIMES NOTABLE BOOK

How much credit do parents deserve when their children turn out welt? How much blame when they turn out badly? Judith Rich Harris has a message that will change parents' lives: The "nurture assumption" -- the belief that what makes children turn out the way they do, aside from their genes, is the way their parents bring them up -- is nothing more than a cultural myth. This electrifying book explodes some of our unquestioned beliefs about children and parents and gives us a radically new view of childhood.

Harris looks with a fresh eye at the real lives of real children to show that it is what they experience outside the home, in the company of their peers, that matters most, Parents don't socialize children; children socialize children. With eloquence and humor, Judith Harris explains why parents have little power to determine the sort of people their children will become.

The Nurture Assumption is an important and entertaining work that brings together insights from psychology, sociology, anthropology, primatology, and evolutionary biology to offer a startling new view of who we are and how we got that way.

The author of the controversial book The Nurture Assumption tackles the biggest mystery in all of psychology: What makes people differ so much in personality and behavior? It can't just be "nature and nurture," because even identical twins who grow up together same genes, same parents have different personalities. And if psychologists can't explain why identical twins are different, they also can't explain why each of us differs from everyone else. Why no two people are alike. Harris turns out to be well suited for the role of detective it isn't easy to pull the wool over her eyes. She rounds up the usual suspects and shows why none of the currently popular explanations for human differences birth order effects, for example, or interactions between genes and environment can be the perpetrator she is looking for. None of these theories can solve the mystery of human individuality. The search for clues carries Harris into some fascinating byways of science. The evidence she examines ranges from classic experiments in social psychology to cutting-edge research in neuroscience. She looks at studies of twins, research on autistic children, observations of chimpanzees, birds, and even ants. Her solution is a startlingly original one: the first completely new theory of personality since Freud's. Based on a principle of evolutionary psychology the idea that the human mind is a toolbox of special-purpose devices Harris's theory explains how attributes we all have in common can make us different. This is the story of a scientific quest, but it is also the personal story of a courageous and innovative woman who refused to be satisfied with "what everyone knows is true." "
