In this book, Dr. Adrian Raine presents the growing body of evidence that shows how genetics and environmental influences can conspire to create a criminal brain, and how something as seemingly innocent as a low resting heart rate can give rise to a violent personality. Bristling with ingenious experiments, surprising data, and shocking case studies, this is also a clear-eyed inquiry into the thorny ethical issues this science raises about prevention and punishment.
