Agree with this. I also realize I wasn't clear here, so lets says you have a person A who is a sociopath talk to person B. After that interaction person A comes to person C (me in this example) and says "I don't know, they strike me as a sociopath." Now in these cases, when I've had enough interaction with Person A in other situations, to feel confident in my understanding of their challenges, and when the feedback on Person B from other sources are not reflective of that perception, and are typically hard over the other way ("this person is so empathic" kinds of things). I hypothesize that the body language of Person B was signaling to Person A that their masking was not as effective as they would have liked. The other thing I wanted to be clear about is that it isn't a judgement about them either way, people are who they are. What is important as a manager is understanding the dynamics of your team and how they perceive the world and evaluate it. One has to do that if you have any chance at all of working together effectively.
