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 twenty-five—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 twenty-five everyday Americans, therefore, is secretly a sociopath. They could be your colleague, your neighbor, even family. And they can do literally anything at all and feel absolutely no guilt.

It is the ruthless versus the rest of us, and The Sociopath Next Door will show you how to recognize and defeat the devil you know.

These days, no one in America feels immune to violence. But now, in this extraordinary groundbreaking book, the nation's leading expert on predicting violent behavior unlocks the puzzle of human violence and shows that, like every creature on earth, we have within us the ability to predict the harm others might do us and get out of its way. Contrary to popular myth, human violence almost always has a discernible motive and is preceded by clear warning signs.

Through dozens of compelling examples from his own career, Gavin de Becker teaches us how to read the signs, using our most basic but often most discounted survival skill - our intuition. The Gift of Fear is a remarkable, unique combination of practical guidance on leading a safer life and profound insight into human behavior.
