I can't answer your question directly, but psychopaths are marked by their lack of empathy and foresight. Because of this, they also are much more likely than the general populace to have criminal records. I suspect that no competent rater would ever mistakenly declare someone in the normal range a psychopath.

Psychopaths actually have abnormal brain structures:

I think INTJs could easily be the most likely type that the average person out there would identify as a troubled loner. It is probably too much to expect the average person to understand that most INTjs are quite content loners as opposed to troubled loners.

Well.....

according to Jungian John Beebe, his anecdotal evidence shows that characters in contemporary American films representing the function of introverting iNtuiting (Ni, an IN_J's favorite function and best gift) tend to portray it via "a psychotic serial-killer, some kind of weird, offbeat sociopath who would give you the creeps."

According to John, Ni is the deepest shadow of our ESTJ culture. He gives an example of Ni in movies with the famous shower scene from "Psycho," and says this is an example of "demonic Ni," meaning this is how most of the culture views and experiences it.

He claims it is also a very unpopular function in general. (It's harder on the INFJs than the INTJs, I can tell you.)

He also claims that Carl Jung singlehandedly rescued the gift of introverted iNtuiting from being relegated to sociopathy in the psycholoical field.

I want to clarify here that I don't believe INTJs *ARE* psychopaths or most likely to *BE* psychopaths, but there is an UNFAIR perception around the Ni function that lends itself to this stereotype.

psychopathy is marked by

1. Superficial charm and above average intelligence.
2. Absence of delusions and other signs of irrational thinking.
3. Absence of nervousness or neurotic manifestations.
4. Unreliability.
5. Untruthfulness and insincerity.
6. Lack of remorse or shame.
7. Antisocial behavior without apparent compunction.
8. Poor judgment and failure to learn from experience.
9. Pathological egocentricity and incapacity to love.
10. General poverty in major affective reactions.
11. Specific loss of insight.
12. Unresponsiveness in general interpersonal relations.
13. Fantastic and uninviting behavior with drink, and sometimes without.
14. Suicide threats rarely carried out.
15. Sex life impersonal, trivial, and poorly integrated.
16. Failure to follow any life plan.

i can see where these characteristics may be interpreted as being indicative of the INTJ.. because they all allude to a person who exists within a fortress of their own paradigm.. someone with no regard for their surroundings.. and little respect for social norms. but! they must be understood within the context of psychopathy.. as a diagnosis presented to explain a person’s severe challenges when relating [ineffectively, no less] to their environment..

now i beg to differ that these are indicative of the [*n.b. 'balanced'!] INTJ because while you can subjectively interpret these characteristics on an individual basis and most likely get an affirmation, [.. like #13 ok for sure it applies cos sometimes speaking your mind doesn't always make for the best small-talk..]within the context of INTJness these indicators would really only apply in as much as yes, we maintain unique perspectives, and attempt to implement them.. but to the point of the disassociative tendencies implied in those diagnostics? i don’t think so. we are a lot more flexible and adaptive from what I understand of myself n the type generally, and we are particularly sensitive to the nuances and dyamism in our environment.
[an interesting thing I read a while back was that Dr. Hannibal 'cannibal' Lecter [a prime example of secondary psychopathy], is a fictional INTJ.. and interestingly, so too is his 'pursuer', Clarice Starling [an INTJ not a sociopath]! so psychopathic or not, we may be ‘gifted’ with the inherent understanding of the criminal mind no less..//..?..]

also i noticed Bill suggested that Josh consider psychosis.. which is the state of breaking with reality.. and i was only thinking about this myself earlier this evening.. when we live in a world so marked by Progress, by breaking boundaries, pushing the envelope, scientific discoveries, thought revolution, archaeological findings.. is it really so easy to define 'reality'? after all, many geniuses [artists, scientists, writers, philosophers] are considered insane or laughable in the lead up to an acknowledgement of their true intelligence n insight [one man's spinach is another man's poison ivy.] our realities are contingent upon so many factors!
*sigh*.

I think that INTJs are often seen as possible psychopaths, however, MB types describe 'normal' personality types and psychopathology(pathology of an individual's psychology) seems to be a description of 'abnormal' psychology, so I don't think such beliefs are accurate per se...

yes, becuase people don't understand INTJs. we are a mystery to everyone around us. we could never be psychopaths, however, becuase we are not 'impulsive' or have any 'charm' to speak of.

I wrote an article about INTJs and psychopaths for PoliceOne.com. The purpose of the article was to warn officers, in a light hearted way, to be extremely cautious about making judgments without sufficient evidence. INTJs are similar to psychopaths in very superficial ways. If one digs deeper, they are quite different. Although, I must admit, I did meet one INTJ who was a psychopath. Both types are very intelligent and talented, though usually in different areas. I have no data on the Myers-Briggs and psychopaths, but I would be very surprised if a large number are INTJs.

Apparently people in high school & college thought I was going to "blow up the school" (their words, not mine), I guess because I usually walked around with a pretty serious & focused look on my face and did not socialize unnecessarily. I did not make small talk or attempt to build any social network beyond what felt natural or was necessary to complete my work. And I am not a natural smiler, my facial expression is usually pretty rigid and "grim" to most people (though it feels perfectly natural to me). I smile when I'm happy but I did not enjoy school for the most part. "Blowing up the school" was not in my plans at all; I harbor no love for those institutions but I am not nearly so innately destructive -- and besides why would I want to kill/injure a bunch of hot babes?

It is safe to say most people didn't really "like" me because I made almost no effort to fit in and be like everyone else, I just thought I was different or something (and most evidence points to this being true). Probably only a few thought I was a genuine psychopath/sociopath.

The truth probably lies somewhere in the middle; I feel pretty crazy sometimes but I have little trouble blending into society without causing much of a ruckus. Also I have known some people who actually ARE certifiably crazy and I am definitely not crazy compared to them. I can be pretty psychically/emotionally vicious & ruthless when someone goes out of their way to stab me in the back but those cases are highly personal and it is rare that I let someone in far enough to be able to bring that side out of me. And even in such cases it has never devolved into physical violence or anything that could get me into legal trouble.
