The other day, I was discussing with someone the recent story about George Zimmerman’s girlfriend accusing him of pointing a gun at her. We both agreed that the interesting part of the story wasn’t so much that Zimmerman was in trouble, but that Zimmerman – a man who has quite a lot of very recent baggage, not much seemingly going for him, and, having only been served with divorce papers days ago, is married – even has a girlfriend. We both wondered why a woman would want to be his girlfriend at the moment in the first place.

Apparently, Saturday Night Live did too, as they led off this weekend’s episode with a sketch in which this very question is asked.

Now, I am not claiming that George Zimmerman is a psychopath or has any other specific conscience-reducing disorder. I really have no ability to make a judgment on that. However, the conversation about his romantic situation did lead me to explain to my conversation partner that those that are psychopaths or do have certain related disorders are notorious for their ability to attract many romantic and sexual relationships. I mentioned some of the fascinating research, which I cover in my foundational page about psychopathy, about just how successful some of history’s most ruthless killers have been in spreading their genes.

Well, as so often happens after a deep discussion about an intriguing topic, it wasn’t more than a couple of days before a new, highly relevant story emerged in the news. (more…)

One of the most challenging and important questions in ponerology is whether conditions associated with reduced empathy and conscience, and thus with increased likelihood of harmful malicious and neglectful activity, are caused by nature (genes, biology, etc.) or nurture (environment, upbringing, etc.)

Most who work in the fields that study aspects of this question take the view that the answer involves some combination of the two.

But this still leaves us with another question. In what proportion do each of these factors contribute in which people?

One remarkable case offers some fascinating insight on the subject.

Dr. James Fallon

James Fallon, Ph.D. is a highly decorated neuroscientist and Professor Emeritus of Anatomy and Neurobiology at University of California, Irvine. Dr. Fallon has several areas of expertise. One is adult stem cells. Another is psychiatry. Specifically, he is interested in the relationships between brain imaging (he has served as Director of UC Irvine’s Human Brain Imaging Center), genetics and various psychiatric conditions, including schizophrenia, depression and addictions.

An Extraordinary Experiment

Aware of his specialties, for many years, Fallon’s colleagues have sent him brain images they wished to have him analyze.

At one point this interchange took the form of an experiment.

Colleagues sent him 70 MRI scans of brains belonging to people ranging from healthy to mentally ill. Included in the batch were scans of brains belonging to killers, including some notorious ones. But Fallon had no idea which scanned brain belonged to whom.

Nonetheless, he was able to identify differences in five of the scans so dramatic that he could recognize them as the markers of psychopathy. And it turned out that he was correct. The five scans on which he zeroed in actually were those from the brains of psychopathic serial killers. (more…)
