Jim Fallon of UC Irvine is a good friend and former professor. He’s all over the news this week because of he’s found a correlation between his brain imagery, his genetics and those of psychopaths. He’s also apparently related to the famed Lizzie Borden.
But before we go out and profile the population for violent crazies, a couple of important cautions:
First, Jim Fallon is definitely not a psychopath. Having known him for thirty years, loyal readers can rest assured. So the correlation is not sufficient for the phenotype.
Second, it’s likely that there are many varieties of psychopaths. As there are many kinds of cancer, each with its own specific etiology, so there are many brain disorders which may lead to what we might legally call psychopathic behavior. My guess is that the variability here is enormous.
