There is a book called Snakes In Suits: When Psychopaths Go To Work.
The following is some pertinent information, excerpts, and quotes from the book.
Book Disclaimer: "Only qualified psychologists or psychiatrists can diagnose a personality disorder, including psychopathy, and differentiate it from others that may look similar. It is important to note that psychopathy is a personality disorder, and that personality disorders are not the same as mental illness."
"We consider it important to caution the reader that, although the topic of this book is psychopathy in the workplace, not everyone described herein is a psychopath. The "snakes" we describe are not based on actual persons, and any resemblance to such persons, (or CEOs) living or dead, is purely coincidental. The reader should not assume that an individual is a psychopath simply because of the context in which he or she is portrayed in this book."
"Covert attacks and defensive maneuvers waste valuable time and energy that could otherwise be focused on creativity, productivity, and profitability. In addition, bruised egos and lowered morale are much harder to measure but can lead to large declines in organizational performance. Even loyal coworkers--firsthand witnesses to much of the psychopath's machinations--do not always understand what is happening. And, when some do raise the red flag, they may find that no one at the top responds to it. This book evolved out of our growing realization that lack of specific knowledge about what constitutes psychopathic manipulation and deceit among businesspeople was the corporate con's key to success."
According to the PCL: SV Manual a psychopath is SUPERFICIAL, GRANDIOSE, DECEITFUL, LACKS REMORSE, LACKS EMPATHY, & DOES NOT ACCEPT RESPONSIBILITY. More extensive descriptions are provided in the book Without Conscience.
Psychopathy, Sociopathy, and Antisocial Personality Disorder
Many people are confused about the differences among psychopathy, sociopathy, and antisocial personality disorder. Although the terms frequently are treated as if they are interchangeable--by the general public and professionals alike--they refer to related but not identical conditions. Psychopathy is a personality disorder described by the personality traits and behaviors that form the basis of this book. Psychopaths are without conscience and incapable of empathy, guilt, or loyalty to anyone but themselves. Sociopathy is not a formal psychiatric condition. It refers to patterns of attitudes and behaviors that are considered antisocial and criminal by society at large, but are seen as normal or necessary by the subculture of social environment in which they developed. Sociopaths may have a well-developed conscience and a normal capacity for empathy, guilt, and loyalty, but their sense of right and wrong is based on the norms and expectations of their subculture or group. Many criminals might be described as sociopaths. Antisocial personality disorder (APD) is a broad diagnostic category found in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV). APD is similar to sociopathy. Some of those with APD are psychopaths, but many are not. The difference between psychopathy and antisocial personality disorder is that the former includes personality traits such as lack of empathy, grandiosity, and shallow emotion that are not necessary for a diagnosis of APD.
According to Cleckley, psychopaths come across as having a superficial charm and good intelligence. Psychopaths are often entertaining and can tell creative, believable stories. They don't seem to experience delusional or irrational thinking, which often characterizes a mental disorder, and they tend not to be anxious or neurotic. On the surface, then, they appear normal, sane, and in control; in fact, many are quite likable. As Cleckley put it, "[the] psychopath presents a technical appearance of sanity, often one of high intellectual capacities, and not infrequently succeeds in business or professional activities." The title of his book, The Mask of Sanity, reflected Cleckley's belief that, although psychopaths do not exhibit the obvious symptoms of mental illness, they suffer from a profound underlying disorder in which the language and emotional components of thought are not properly integrated, a condition he called semantic aphasia. As noted in Without Conscience, the elements needed for the development of psychopathy--such as a profound inability to experience empathy and the complete range of emotions, including fear--are provided in part by nature and possibly by some unknown biological influences on the developing fetus and neonate. As a result, the capacity for developing internal controls and conscience and for making emotional "connections" with others is greatly reduced. More extensive descriptions are provided in the book, Without Conscience.
Grandiose, superficial, deceitful, lacks remorse, lacks empathy, doesn't accept responsibility, and impulsivity are just some of the traits associated with psychopathy. The PCL-R checklist is one tool used by professionals to assess psychopathy and or the level of it. Psychopaths simply do not care if what they say and do hurts people as long as they get what they want, and they are very good at hiding this fact. Given his or her powerful manipulations skills, it is little wonder why seeing a "psychopathic" personality beneath someone's charming, engaging surface is so difficult. The book focuses less on bully psychopaths and more on those who are capable and willing to use their "deadly charm" to con and manipulate others. Psychopaths lack empathy and possibly even the most basic understanding of human feelings. Characteristically, the economic and emotional impact of their selfish behavior on others is irrelevant to them, in part because they believe everyone in this dog-eat-dog world is as greedy and unfeeling as they are. Psychopaths also lack feelings of remorse and guilt, part of the internal moral sense that prevents the rest of us from acting out some of the fantasies we occasionally have about using, manipulating, or hurting others. Some might suggest that psychopaths are such effective predators because they are not plagued by doubts and concerns raised by a conscience. Psychopaths have a great sense of superiority and entitlement. Narcissism is a key psychological trait of psychopaths.
