I took an online test and scored as an INTJ.
As it says in Wikipedia:
“INTJs are one of the rarest of the sixteen personality types, and account for about 1–4% of the population”
- I – Introversion preferred to extraversion: INTJs tend to be quiet and reserved. They generally prefer interacting with a few close friends rather than a wide circle of acquaintances, and theyexpend energy in social situations (whereas extraverts gain energy).
- N – Intuition preferred to sensing: INTJs tend to be more abstract than concrete. They focus their attention on the big picture rather than the details and on future possibilities rather than immediate realities.
- T – Thinking preferred to feeling: INTJs tend to value objective criteria above personal preference. When making decisions they generally give more weight to logic than to social considerations.
- J – Judgment preferred to perception: INTJs tend to plan their activities and make decisions early. They derive a sense of control through predictability, which to perceptive types may seem limiting.
There’s also a forum especially for INTJs. Pretty informative for others and comforting to intjs http://intjforum.com/
