I am not a fan of Criminal Minds and its ilk, as these TV shows often suggest that forensic work is easy, simple, and glamorous. I think life happens in the quiet spots rather than the highs and lows, and I appreciate the quiet and small. As a result, I was initially turned off by Kent Kiehl's tone in Psychopath Whisperer: The Science of Those Without Conscience: he was glib and seemed to be choosing his subjects for their shock value. It was worth persevering.
Psychopath Whisperer is three things: a study of psychopaths, an intellectual memoir of Kiehl's life, and a description of the scientific process. Most readers will probably focus on the first, but the latter two are at least as interesting. Kiehl's life and work was not easy and simple but, as he describes it, the consequence of long, hard hours of work; thousands of articles read; savvy networking; good mentoring, probably the consequence of some of the above; good advice; and (probably) his quad espressos. As he said about two of my friends (and others):
Dr. Long called a couple of other professors, Dr. Michael Gazzaniga, the founding father of the field of cognitive neuroscience (the study of how the brain processes information), and Dr. George Mangun, an attention researcher, both of whom had just relocated their laboratories from Dartmouth University to UC Davis. She told them that she had a motivated undergrad she was sending their way. Next she called Dr. Carolyn Aldwin in the human development department. Carolyn was married to Dr. Michael (Rick) Levenson, a research professor who studied psychopathy, among other conditions. She also set me up to see a lecture by Michael Szymanski, a graduate student who was studying brain electrical activity in killer whales. Wow! Dr. Long still receives free drinks anytime our paths cross. All of the individuals she contacted that day became mentors and lifelong friends, and eventually, I am honored to say, I came to be called a colleague by them. (p. 15)
Why did Long make these introductions? Probably because Kiehl was a bright and hardworking undergraduate. Why did they stay in his life? Because he was exceptionally hardworking, dedicated, and focused, and early knew the value of sharing out-of-date and easily available bags of Starbucks coffee. Relationships open doors that would otherwise stay closed.
In Psychopath Whisperer, Kiehl straddles the cusp between abstract and concrete in a way that satisfies me. For example, as he talks about the Psychopathy Checklist – Revised (PCL-R), Kiehl discusses two men who killed US presidents. They committed similar-seeming acts, yet Kiehl argues that Charles Geiteau was a psychopath, who would score in the 99th percentile of the PCL-R, Garfield's murder relatively meaningless, with Geiteau experiencing little (no???) guilt and shame. John Wilkes Booth, on the other hand, killed Lincoln for reasons most of us don't agree with, yet they were part of his deep commitment to the South. His psychopathy score was higher than that of the average man, yet still relatively low.
All criminals are not psychopaths and, probably, not all psychopaths are criminals (or at least found in prison).
We often want to know: nature or nurture? Was Ted Bundy born or made that way? Kiehl provides considerable evidence that would support either end of this hypothesis. Psychopaths often come from abusive and chaotic families, with parents who used authoritarian parenting strategies. (Why aren't their siblings also psychopaths?) On the other hand, there is convincing research that structures in the paralimbic sections of the brain, those typically involved in processing emotions and emotional memories, are less active than those of nonpsychopaths during tasks eliciting emotional processing. His argument seems to support both nature and nurture, as most psychologists respond when asked this question. Nonetheless, Caldwell and Van Rybroek's research from the Mendota Juvenile Treatment Center in Wisconsin convincingly concludes that they can change. (At least callous and unemotional youth, likely youth who will become psychopaths, can change.)
In sum, this book has something for everyone, and is worth reading.
