Here’s a medical riddle: When is just a touch of a disease worse than the full-blown thing?
And here’s a hint: worse for whom? Suppose it’s not the sick person you’re worried about, but that individual’s friends, family, colleagues and clients? The authors of “Almost a Psychopath” suggest that people with just a few of the dangerous characteristics of a psychopath may take a greater toll on the community than those with the real diagnosis, only because the partly psychopathic are so much more pervasive and elusive.
“Psychopaths are part of our professional lives,” write the authors (Dr. Ronald Schouten has both law and medical degrees and is a psychiatrist at Harvard Medical School; James Silver is a criminal defense lawyer). Most people, though, are unlikely to run into one of these career criminals; experts estimate that they constitute only about 1 percent of the population.
It is far more common to fall under the wheels of someone on the psychopathic spectrum, with enough of the charm, egoism, deceitfulness, aggression, manipulativeness and lack of empathy to ride blithely over the heads of others — and just enough normalcy to avoid detection. In fact, what these authors call “almost psychopaths” are also called “successful psychopaths,” because they often do quite well in life despite the gradual accumulation of victims in their wake."
