Based on my experiences, I would say this person the article speaks of is more probably a schzoid type personality, or borderline personality disorder?  I think the popular media driven depiction of psychopaths as bombastic assholes to be click-bait - real psychopaths are a lot more like Patrick Bateman (&quot;American Psycho&quot;) - cool as a cucumber and always in control of their emotions<p>And thus the interaction they have with people.  They&#x27;re like an information black hole - little leaks out of them, but they are sucking up every bit of non-verbal etc info out of you and consciously processing it. Thus they see your blind spots and can devise ways to take advantage of your &#x27;shadow&#x27; side or hidden psychological needs.
