Is there a biological basis for evil? From neurological imaging to behavioral studies, Dean Haycock's account of the groundbreaking research reveals what scientists are learning about the psychopaths living among us.



How many times have you seen a murder on the news or on a TV show like CSI: Crime Scene Investigation, and said to yourself, "How could someone do something like that?" Today, neuroscientists are imaging, mapping, testing and dissecting the source of the worst behavior imaginable in the brains of the people who lack a conscience: psychopaths. Neuroscientist Dean Haycock examines the behavior of real life psychopaths and discusses how their actions can be explained in scientific terms, from research that literally looks inside their brains to understanding out psychopaths, without empathy but very goal-oriented, think and act the way they do. Some don’t commit crimes at all, but rather make use of their skills in the boardroom. But what does this mean for lawyers, judges, psychiatrists, victims and readers--for anyone who has ever wondered how some people can be so bad. Could your nine-year-old be a psychopath? What about your co-worker? The ability to recognize psychopaths using the scientific method has vast implications for society, and yet is still loaded with consequences.
