So nearly everyone loves Shaw's no nonsense, cut to the chase delivery, usually at gunpoint, on Person of Interest. She's fun, no doubt! But I'm speaking here as a person who only started following the series in the third season, a few episodes before the Machine Gang took down HR, and I'm wondering if she's really a psychopath.

The reason I ask is because, I've known two psychopaths (On the milder, habitual lying, parasitic end, not the just as soon go kill people as go fishing end.). I'm also thinking about this article and I don't think she really fits the diagnosis. Sure, sure empathy is not her strong point but it also seems like all her other emotional responses are very low key. And the ones I know aren't really like that. They experience joy and rage very clearly even if their empathy and impulse control were all messed up.

She doesn't really get angry, just frustrated. She doesn't really experience joy, just a smug satisfaction at doing her job well. It's as if there is some kind of general damage to her limbic system (The paleomammalian brain.). She's a bit like Mr. Spock with more sarcasm and less religious repression.

I'm not a psychiatrist or psychologist but it is an intriguing question—what kind of brain damage does Shaw have? Does she map to any known illness in the DCM or ICD?
