Judith Rich Harris is an independent investigator and a former writer of textbooks in child development. She lives in New Jersey with her husband.
Why do identical twins who grow up together differ in personality? Harris attempts to solve that mystery. Her initial thesis in The Nurture Assumption: Why Children Turn Out the Way They Do is replaced here with a stronger, more detailed one based on evolutionary psychology. Reading this book is akin to working your way through a mystery novel-complete with periodic references to Sherlock Holmes. And Harris has a knack for interspersing scientific and research-laden text with personal anecdotes. Initially, she refutes five red herring theories of personality differences, including differences in environment and gene-environment interactions. Eventually, Harris presents her own theory, starting from modular notions of the brain (as Steven Pinker puts it, "the mind is not a single organ but a system of organs"). Harris offers a three-systems theory of personality: there's the relationship system, the socialization system and the status system. And while she admits her theory of personality isn't simple, it is thought provoking. Harris ties up the loose ends of the new theory, showing how the development of the three systems creates personality. Harris's writing is highly entertaining, which will help readers stick with her through the elaboration of a fairly complex theory. 12 b&w illus. (Feb.) Copyright 2005 Reed Business Information.
"A display of scientific courage and imagination." -- William Salatan - New York Times "As she did in The Nurture Assumption, independent scholar Harris makes waves again with a new theory of personality to explain why no two people are alike." -- Kirkus Reviews
In this follow-up to her controversial 1998 book, The Nurture Assumption: Why Children Turn Out the Way They Do, Harris presents what may be the best personality theory since Sigmund Freud's. Why do identical twins with the same genes and raised in the same household grow up with different personalities? According to Harris, adept brains and complex culture account for the difference. With neither a doctorate nor a university behind her, Harris more than compensates with intelligence, dogged research, lively writing, a love of mystery, and droll humor. She wrestles bulging files of research data into shape, in the process taking down some champions of the old order, including Freud, James Watson, Eleanor Maccoby, and Frank Sulloway. Her three-systems theory of personality postulates a modular brain that must from infancy learn the particulars of relationships along with abstract principles of language and socialization. Harris makes behavioral genetics and evolutionary psychology enjoyable and accessible to general readers as well as scholars. Essential for general and academic libraries.-E.
