Introverted Intuition supported by Thinking. In her book, Gifts Differing, Isabel Briggs Myers calls the INTJ the most independent of the 16 types and claims that we take more or less conscious pride in our independence.

"Whatever their field, they are likely to be innovators. In business, they are born reorganizers. Intuition gives them an iconoclastic imagination and an unhampered view of the possibilities; extroverted thinking supplies a keen critical organizing faculty. 'Whatever is, could be doubtless improved.' They are likely, however, to organize themselves out of a job. They cannot continually reorganize the same thing, and a finished product has no more interest. Thus, they need successive new assignments, with bigger and better problems, to stretch their powers.

With technical interests, they tend to be research scientists, inventors, and design engineers. They are likely to be very good at mathematics, especially problems, but not as adept at pure mathematical theory as INTPs. INTJs are fine at thinking things up, and definitely better at working things out than the INTPs. They can get things done, but they will be interested only when the problems involved are complicated enough to be challenging. Routine production would waste the intuition, and a purely theoretical research job would waste the extraverted thinking, which has a craving for practical applications of ideas.

Even when well-balanced, they have a tendency to ignore the views and feelings of other people. Use of the critical attitude in personal relations is a destructive luxury that can have a disintegrating effect upon their private lives. They would do well to make an effort to use their critical faculty on their impersonal problems and on themselves and to work for some development of appreciation (they need not call it feeling) to use on others."
