Schizophrenia is a widely investigated psychiatric condition, and though there have been claims of gene "associations," decades of molecular genetic studies have failed to produce confirmed causative genes. In this book, Joseph focuses on the methodological shortcomings of schizophrenia genetic research. His findings have major implications not only on how we understand the causes of schizophrenia and other psychiatric conditions, but also on how we understand the causes of human behavior in general. Chapters explore the differing theoretical concepts of schizophrenia, molecular genetic research around schizophrenia, family, twin, and adoption studies, and non-medical prevention and intervention strategies. Prominent researchers and studies in the field are discussed and critiqued comprehensively throughout. This book is essential reading for psychiatrists, psychologists, behavioral scientists, and anyone interested in the causes of human behavior.

The Trouble with Twin Studies questions popular genetic explanations of human behavioral differences based upon the existing body of twin research. Psychologist Jay Joseph outlines the fallacies of twin studies in the context of the ongoing decades-long failure to discover genes for human behavioral differences, including IQ, personality, and the major psychiatric disorders. This volume critically examines twin research, with a special emphasis on reared-apart twin studies, and incorporates new and updated perspectives, analyses, arguments, and evidence.

Can genes determine which fifty-year-old will succumb to Alzheimer's, which citizen will turn out on voting day, and which child will be marked for a life of crime? Yes, according to the Internet, a few scientific studies, and some in the biotechnology industry who should know better. Sheldon Krimsky and Jeremy Gruber gather a team of genetic experts to argue that treating genes as the holy grail of our physical being is a patently unscientific endeavor. Genetic Explanations urges us to replace our faith in genetic determinism with scientific knowledge about how DNA actually contributes to human development. The concept of the gene has been steadily revised since Watson and Crick discovered the structure of the DNA molecule in 1953. No longer viewed by scientists as the cell's fixed set of master molecules, genes and DNA are seen as a dynamic script that is ad-libbed at each stage of development. Rather than an autonomous predictor of disease, the DNA we inherit interacts continuously with the environment and functions differently as we age. What our parents hand down to us is just the beginning. Emphasizing relatively new understandings of genetic plasticity and epigenetic inheritance, the authors put into a broad developmental context the role genes are known to play in disease, behavior, evolution, and cognition. Rather than dismissing genetic reductionism out of hand, Krimsky and Gruber ask why it persists despite opposing scientific evidence, how it influences attitudes about human behavior, and how it figures in the politics of research funding.
