Although INTJs (Myers-Briggs personality Type profile) share some of the same characteristics as the psychopath, the appearance of shallow emotions and an idiosyncratic value system, especially as it applies to sexuality, they are not normally psychopaths.
Whereas, psychopaths have very sallow emotions, INTJs appear to be unemotional. Actually, they can be hypersensitive on some levels, especially with the few people about whom they care. They are not as responsive to praise or criticism as some of the other personality types. They show the world a veneer of calm self-confidence, which can be mistaken for arrogance (I am being generous here).
INTJs tend to be introspective, more at home with theories and principles than human relationships. They have an endearing tendency to look at one over their glasses or raise one eyebrow to show disapproval. They make up about one percent of the population. INTJs are quite often highly educated, successful individuals, because they can be unusually intelligent. Though, they are not particularly interested in accumulating wealth.
She then gives a list that actually makes INTJs seem a lot like sociopaths. Of course this doesn't mean that sociopaths can't be INTJs... But that doesn't mean INTJs are sociopaths. INTJs apparently only seem cold, but really are just cold on the exterior. Other differences include:
The psychopath will come into contact with the criminal justice system because he or she is impulsive, amoral, opportunistic and irresponsible. INTJs are impulsive under stress. However, they are more likely to shoot themselves in the foot (figuratively speaking, folks) than shoot their maiden aunt to acquire her fortune. Remember, most INTJs are not dazzled by material possessions. Though, I have seen a few who liked their toys. They may quit their job when their feathers are ruffled, without wondering how they will pay the bills. INTJs can also be highly insulted if someone dares question their ideas or principles, because they are convinced of the "rightness" of their beliefs. Yawn. Nonetheless, they probably will not bury their Nemesis in the backyard. It is much more likely that crimes will be committed by psychopaths.
Of course it's possible that INTJs are sociopaths or vice versa:
There is no law that says a psychopath cannot be an INTJ. However, I would be surprised if that were the case. INTJs are normally boringly responsible individuals. Consequently, if you have someone with a spotty employment record, he is probably not an INTJ...start wondering about psychopath. Be cautious, one trait does not a psychopath make.
Hmm, spotty employment record...
But can you imagine good old Myers and Briggs envisioning this sort of use for their personality distinctions when they made them? Or Jung, for that matter? It's become the seemingly legitimate astrology of the masses.
[Like that graph I used for the picture? Can you imagine working at a place with that many INTJs? Talk about society of sociopaths, right? It actually comes from a group of intelligence analysts.]
