I just got around to listening to this This American Life episode on psychopaths:
It's largely more of the same from the NPR articles, but in audio format. More from Jon Ronson about sociopathic CEOs, sociopathic stares, small amygdalas make you "dangerous," and the role that the "predatory spirit" plays in success.
The most entertaining section is the part about Jon Ronson meeting a sociopathic seeming CEO who fired an employee who happened to be bragging about his car thusly: "You may have a fancy sportscar, but I'll tell you what you don't have -- a job." Gasp! Psychopaths can be so straightforward and tactless!!!!!
Spoiler alert, host Ira Glass practically outs himself as a sociopath, but not really, according to the psychologist, because he wasn't malicious enough (is that the hidden PCL-R trait, that only psychologists are privy to?)
