Jon Ronson's thought-provoking The Psychopath Test: A Journey Through the Madness Industry is certainly one of the best new books of the year. Though not the first to make these revelations, the book is one of the best on the subject, journalism structured in such a way to create a tension in the narrative, to make the outcome seem in doubt.
Then at the end, Ronson makes readers question what they have read--so that they can come to their own conclusions. Can psychopaths be cured and taught to feel empathy? Probably not in this lifetime. Are those damn ruthless CEOs psychopaths? Those who lay people off gleefully while they ruin their companies, their employees, and their stockholders? Probably so.
