I heard about this on NPR recently, on the series This American Life, and found it fascinating. I have included the link to the radio broadcast, which is a bit long, but the third part is especially interesting. This sounds like an odd topic for the Politics forum, but when you think about it, it makes sense.
In a nutshell, a few years ago a Canadian psychologist realized there was no real test to detect psychopathy. So he came up with his own. At first law enforcement officials didn't treat it seriously, but is now used extensively, not exactly to the pleasure of the man who came up with it. He seems to think many in LE will not give the test competantly, and he may well be right.
Having administered it himself many times, he found that approximately 1% of the general population exhibited significant psychopathic tendencies. That is in part defined by a complete lack of empathy. As if that part of their brain was missing, and a picture of a grisly murder scene meant no more to them emotionally then a picture of a chair. Nearly 25% of those in the justice system also did. Not overly surprising. What struck me was that over 4% of corporate executives also demonstrated a strong inclination towards paychopathy. 4 times the general public. Worth a listen if you have the time.
