To outsiders, INTJs may appear to project an aura of "definiteness", of self-confidence. This self-confidence, sometimes mistaken for simple arrogance by the less decisive, is actually of a very specific rather than a general nature. INTJs know what they know, and perhaps still more importantly, they know what they don't know.
INTJs apply (often ruthlessly) the criterion "Does it work?" to everything from their own research efforts to the prevailing social norms. This in turn produces an unusual independence of mind, freeing the INTJ from the constraints of authority, convention, or sentiment for its own sake.
that was what the test got right.

As for my own judgement, I have to admit that I have a hard time grouping me with either extreme. I spend my entire working day (the major part of my waking life) as a hyper-assertive extrovert, and it costs me zero effort. On the other hand, much of my private life is spent clichéd-introvert-style.
HMMMM!

Rather amusing (alleged INTJ/ENFP (what.) couple here, and some things are disconcertingly correct, while others are hilarously off).
