INTJ -The Mastermind
You scored 36% I to E, 47% N to S, 76% F to T, and 42% J to P
You are more introverted than extroverted. You are more intuitive than observant, you are more thinking based than feeling based, and you prefer to have a plan rather than leaving things to chance. Your type is best described by the word "mastermind", which belongs to the larger group called rationals. Only 1% of the population shares your type. You are very strong willed and self-confident. You can hardly rest until you have things settled. You will only adopt ideas and rules if they make sense. You are a great brainstormer and often come up with creative solutions to difficult problems. You are open to new concepts, and often actively seek them out.
As a romantic partner, you can be both fascinating yet demanding. You are not apt to express your emotions, leaving your partner wondering where they are with you. You strongly dislike repeating yourself or listening to the disorganized process of sorting through emotional conflicts. You see your own commitments as self-evident and don't see why you need to repeat something already expressed. You have the most difficulty in admitting your vulnerabilities. You feel the most appreciated when your partner admires the quality of your innovations and when they listen respectfully to your ideas and advice. You need plenty of quiet to explore your interests to the depth that gives you satisfaction.
Your group summary: rationals (NT)
Your type summary: INTJ
Some tests have me the other way on the N-S (Intuition vs Sensing, or internally vs externally observant and guided), since I do rank near center on that one.
Fairly strong I (Introversion) and T (Thinking), which is probably not much of a surprise. I suppose some might question the strong I score that know me socially; my tendencies are introverted but I try to consciously extend myself.
This linked site doesn't have them, but I once saw some demographics. INTJ forms less than 1% of the population (the NT family forms around 6%), but about 10% of engineers are INTJ. :>
