Any sociopath/psychopath can game the emotional intelligence system by appearing to be whatever they feel they need to be, to get what they want, and it's not pretty.
No, not any socio/psychopath. Only highly intelligent ones. Average or lower intelligence individuals usually end up in prison. They aren't deterred by threats of punishment so they tend to have serious behavioural problems growing up. It takes a special sort of psychopath to defer rewards in favour of long term success in the absence of the usual punishments associated with child rearing.
"EQ is not a psychometrically valid concept. Insofar as it is anything (which it isn't) it's the Big Five trait agreeableness, although this depends, as it shouldn't, on which EQ measure is being used (they should all measure THE SAME THING). Agreeable people are compassionate and polite, but they can also be pushovers. Disagreeable people, on average (if they aren't too disagreeable) make better managers, because they are straightforward, don't avoid conflict and cannot be easily manipulated."
