We know of psychopaths from chilling headlines and stories in the news and movies - from Ted Bundy and John Wayne Gacy to Hannibal Lecter and Dexter Morgan. As Dr. Kent Kiehl shows, psychopaths can be identified by a checklist of symptoms that includes pathological lying; lack of empathy, guilt, and remorse; grandiose sense of self-worth; manipulation; and failure to accept one’s actions. But why do psychopaths behave the way they do? Is it the result of their environment - how they were raised - or is there a genetic component to their lack of conscience?

Most people are both repelled and intrigued by the images of cold-blooded, conscienceless murderers that increasingly populate our movies, television programs, and newspaper headlines. With their flagrant criminal violation of society's rules, serial killers like Ted Bundy and John Wayne Gacy are among the most dramatic examples of the psychopath. Individuals with this personality disorder are fully aware of the consequences of their actions and know the difference between right and wrong....

In this engrossing journey into the lives of psychopaths and their infamously crafty behaviors, the renowned psychologist Kevin Dutton reveals that there is a scale of “madness” along which we all sit. Incorporating the latest advances in brain scanning and neuroscience, Dutton demonstrates that the brilliant neurosurgeon who lacks empathy has more in common with a Ted Bundy who kills for pleasure than we may wish to admit, and that a mugger in a dimly lit parking lot may well, in fact, have the same nerveless poise as a titan of industry.

We are accustomed to think of sociopaths as violent criminals, but in The Sociopath Next Door, Harvard psychologist Martha Stout reveals that a shocking 4 percent of ordinary people, one in 25, has an often undetected mental disorder, the chief symptom of which is that that person possesses no conscience. He or she has no ability whatsoever to feel shame, guilt, or remorse. One in 25 everyday Americans, therefore, is secretly a sociopath.

Although highly controversial, Hervey Cleckley's Mask of Sanity provides one of the most influential clinical descriptions of psychopathy in the 20th century. At the crux of his argument, Cleckley claims that many psychopathic personalities go undiagnosed because they maintain a social mask that conceals their mental disorder and enables them to blend in with society. Furthermore, many of these affected individuals appear to function normally in accordance with standard psychiatric criteria.

As M. E. Thomas says of her fellow sociopaths, we are your neighbors, co-workers, and quite possibly the people closest to you: lovers, family, friends. Our risk-seeking behavior and general fearlessness are thrilling, our glibness and charm alluring. Our often quick wit and outside-the-box thinking make us appear intelligent - even brilliant. We climb the corporate ladder faster than the rest, and appear to have limitless self-confidence.... Who are we? We are highly successful, non-criminal sociopaths and we comprise 4% of the American population (that's 1 in 25 people!).

We may all know some people who could fit the profile, but sometimes, the term psycho gets used out of context. What defines a psychopath, and how are they different from sociopaths? Psychopathy is not uncommon, and chances are that you might know someone who is one, even though it may have never crossed your mind. To study and understand what a psychopath is and how to look for the signs and subtle differences, is to protect yourself and others, and to get a greater comprehension of the human mind.

From the celebrated neurobiologist and primatologist, a landmark, genre-defining examination of human behavior, both good and bad, and an answer to the question: Why do we do the things we do? Sapolsky's storytelling concept is delightful but it also has a powerful intrinsic logic: He starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs, and then hops back in time from there, in stages, ultimately ending up at the deep history of our species and its evolutionary legacy.

Borderline personality disorder, autism, narcissism, psychosis, Asperger's: All of these syndromes have one thing in common---lack of empathy. In some cases, this absence can be dangerous, but in others it can simply mean a different way of seeing the world. In The Science of Evil, Simon Baron-Cohen, an award-winning British researcher who has investigated psychology and autism for decades, develops a new brain-based theory of human cruelty.

A leading criminologist who specializes in the neuroscience behind criminal behavior, Adrian Raine introduces a wide range of new scientific research into the origins and nature of violence and criminal behavior. He explains how impairments to areas of the brain that control our ability to experience fear, make decisions, and feel empathy can make us more likely to engage in criminal behavior. He applies this new understanding of the criminal mind to some of the most well-known criminals in history. And he clearly delineates the pressing considerations this research demands.

In The Molecule of More: How a Single Chemical in Your Brain Drives Love, Sex, and Creativity—and will Determine the Fate of the Human Race, George Washington University professor and psychiatrist Daniel Z. Lieberman, MD, and Georgetown University lecturer Michael E. Long present a potentially life-changing proposal: Much of human life has an unconsidered component that explains an array of behaviors previously thought to be unrelated, including why winners cheat, why geniuses often suffer with mental illness, why nearly all diets fail, and more.
