In what sounds like the setup for a bad “psychological thriller” movie, neuroscientist James Fallon discovered that his brain fits the profile of a psychopath’s: low activity in the orbital cortex.

“You see that? I’m 100 percent. I have the pattern, the risky pattern,” he says, then pauses. “In a sense, I’m a born killer.”

Fallon’s being tongue-in-cheek — sort of. He doesn’t believe his fate or anyone else’s is entirely determined by genes. They merely tip you in one direction or another.

And yet: “When I put the two together, it was frankly a little disturbing,” Fallon says with a laugh. “You start to look at yourself and you say, ‘I may be a sociopath.’ I don’t think I am, but this looks exactly like [the brains of] the psychopaths, the sociopaths, that I’ve seen before.”

I asked his wife, Diane, what she thought of the result.

“I wasn’t too concerned,” she says, laughing. “I mean, I’ve known him since I was 12.”

Diane probably does not need to worry, according to scientists who study this area. They believe that brain patterns and genetic makeup are not enough to make anyone a psychopath. You need a third ingredient: abuse or violence in one’s childhood.

A sobering reminder of why “neuroscanning” for criminals/terrorists/whatever in airports or elsewehre is a problematic idea.
