Hvem er jeg?

I have taken the Myers-Briggs Personality Type texts at various points throughout my adult life and I think I have always produced the same result, namely INTJ (introvert, intuitive, thinking, judging). I also nearly always promptly forget what my result is, possibly because I more or less equate it with my sun sign (for the curious, I am a Virgo). But for kicks I though I would post a link to a thorough description of the type. I'd also like to be able to refer back to it at some point.

Does it mean anything? I don't really know, but the very first paragraph describes me so perfectly that I have to believe there is more accuracy in this than in the Zodiac:

"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; its source lies in the specialized knowledge systems that most INTJs start building at an early age. When it comes to their own areas of expertise -- and INTJs can have several -- they will be able to tell you almost immediately whether or not they can help you, and if so, how. INTJs know what they know, and perhaps still more importantly, they know what they don't know."

The description of the uncompromising side of my personality is pretty darned apt as well:

"INTJs are known as the 'Systems Builders' of the types, perhaps in part because they possess the unusual trait combination of imagination and reliability. Whatever system an INTJ happens to be working on is for them the equivalent of a moral cause to an INFJ; both perfectionism and disregard for authority may come into play, as INTJs can be unsparing of both themselves and the others on the project."

I think it must be pretty uncomfortable to be the object of my scorn. I know my mother thought so when I was a teenager, and I still feel bad about that. The description gets really interesting (and accurate!) when it comes to interpersonal relationships:

"[...] many INTJs do not readily grasp the social rituals; for instance, they tend to have little patience and less understanding of such things as small talk and flirtation (which most types consider half the fun of a relationship). To complicate matters, INTJs are usually extremely private people, and can often be naturally impassive as well, which makes them easy to misread and misunderstand. Perhaps the most fundamental problem, however, is that INTJs really want people to make sense. [...] This sometimes results in a peculiar naiveté [...] Probably the strongest INTJ assets in the interpersonal area are their intuitive abilities and their willingness to 'work at' a relationship."

What I can't figure out is how such an apparently random list of questions generates such an accurate typology. I guess I'll need to go and read all the other personality descriptions.

ETA: I made KE take the same test. He ended up an INFP.
