I’ve taken these personality tests when I’m bored, sometimes I’ve seen the INTP show up, but more often than not it’s INTJ. I have also taken more extensive personality profiles and INTJ is the outcome. So what is INTJ? According to Wikipedia,
One of the rarest of the sixteen personality types, INTJs account for about 1% of the population.
I also have Asperger’s Syndrome, I like to label this as a personality type as well. I may not even have it, maybe I’m just INTJ. Sounds a bit like denial however since I was diagnosed with it when I was 5 years old. AS makes up about 1% of the population. So, what percent has AS and an INTJ personality? It’s not a high percent 
Seems as if I’m definitely a minority.
Anyway, on to INTJ.
INTJs are strong individualists who seek new angles or novel ways of looking at things. They enjoy coming to new understandings. They tend to be insightful and mentally quick; however, this mental quickness may not always be outwardly apparent to others since they keep a great deal to themselves. They are very determined people who trust their vision of the possibilities, regardless of what others think. They may even be considered the most independent of all of the sixteen personality types. INTJs are at their best in quietly and firmly developing their ideas, theories, and principles.
Yes that does seem to describe me fairly well. I love new ideas and love to brain storm.
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… 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… Personal relationships, particularly romantic ones, can be the INTJ’s Achilles heel… This happens in part because many INTJs do not readily grasp the social rituals… Perhaps the most fundamental problem, however, is that INTJs really want people to make sense.
Yes I have never been a real social person to be honest. That’s pretty apparent no matter what since I have AS.
Masterminds tend to be much more definite and self-confident than other Rationals, having usually developed a very strong will. Decisions come easily to them; in fact, they can hardly rest until they have things settled and decided. But before they decide anything, they must do the research. Masterminds are highly theoretical, but they insist on looking at all available data before they embrace an idea, and they are suspicious of any statement that is based on shoddy research, or that is not checked against reality.
Keirsey refers to an INTJ as a “Mastermind”. Anyway, I do a ton of research on every single thing I do. Then I apply whatever idea I think would work best, but I have many back up plans if that one fails. That’s a perfect description of me. I never, ever embrace an idea until I have done the proper research.
In education they are most often found at the college and university level. In the professions, they may be a lawyer, a business analyst, or strategic planner. Some have a strong artistic/creative bent and may become an artist, inventor, or designer. Whatever they do, they do it with intensity.
Well I don’t know about that, my line of work right now is headed towards programming and affiliate marketing.
This guy reads off the entire description from Keirsey, if you don’t want to read through
