My personality type according to the Keirsey Temperament Theory. Lots of fun and quite accurate in my case.
INTJs, or "Mastermind Rationals", are very analytical individuals, natural strategists, better than any other type at brainstorming approaches to situations. They are more comfortable working alone than with other people, and are not usually as sociable as others, although they are prepared to take the lead if nobody else is up to the task, or they see a major weakness in the current leadership.
Strong-willed and very self-assured, they tend to make decisions quickly. But though they are decisive, they are always open-minded to new evidence and new ideas, flexible in their planning to accommodate changing situations. They are excellent at judging the usefulness of ideas and will apply whatever seems most efficient to them in accomplishing their clearly envisioned goals. To INTJs, what matters is getting it done, and they have a tendency to give little thought to personal cost in getting there. INTJs tend to be very pragmatic and logical individuals, often with an individualistic bent and a low tolerance for spin or rampant emotionalism. They commonly do not recognize authority based on tradition, rank or title.
Persons with this personality type work best given large amounts of autonomy and creative freedom. Analyzing and formulating complex theories are among their greatest strengths. INTJs tend to be acutely aware of their knowledge and abilities. Thus, they develop a strong confidence in their ability and talents, making them "natural leaders." It is this confidence that makes this personality type extremely rare. According to David Keirsey it is found in no more than 1% of the population.
INTJs are very stable, reliable and dedicated. Harmony in relationships and home life tends to be extremely important to the INTJ. He or she tends to withhold strong emotion and does not like to "waste" time with irrational social rituals. This, however, may cause non-INTJs to perceive him or her as distant and reserved.
“ 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. - Marina Margaret Heiss, University of Virginia ”
