INTJs are the most self-confident of all types, having “self-power” awareness. Found in about 1 per cent of the general population, INTJs live in an introspective reality, focusing on possibilities, using thinking in the form of empirical logic, and preferring that events and people serve some positive use. Decisions come naturally to INTJs; once a decision is made, INTJs are at rest. INTJs look to the future rather than the past, and a word, which captures the essence of INTJs, is builder – a builder of systems and the applier of theoretical models.
To INTJs authority based on position, rank, title, or publication has absolutely no force. This type is not likely to succumb to the magic of slogans, watchwords, or shibboleths. If an idea or position makes sense to an INTJ, it will be adopted; if it doesn’t, it won’t, regardless of who took the position or generated the idea. As with the INTP, authority per se does not impress the INTJ. INTJs do, however, tend to conform to rules if they are useful, not because they believe in them, or because they make sense, but because of their unique view of reality. They are the supreme pragmatists, who see reality as something which is quite arbitrary and made up. Thus it can be used as a tool – or ignored. Reality is quite malleable and can be changed, conquered, or brought to heel. Reality is a crucible for the refining of ideas, and in this sense, INTJs are the most theoretical of all the types. Where an ESTP sees ideas as the pawn of reality, an INTJ sees reality as the pawn of ideas: No idea is too farfetched to be entertained.
INTJs are natural brainstormers, always open to new concepts and, in fact, aggressively seeking them. INTJs manipulate the world of theory as if on a gigantic chessboard, always seeking strategies and tactics that have high payoff. In their penchant for logic, the INTJs resemble the INTPs. The logic of an INTP, however, is not confined to the expressible logical. Unlike INTPs, INTJs need only to have a vague, intuitive impression of the unexpressed logic of a system to continue surely on their way. Things need only seem logical; this is entirely sufficient. Moreover, they always have a keen eye for the consequence of the application of new ideas or positions. They can be quite ruthless in the implementation of systems, seldom counting personal cost in terms of time and energy. Theories, which cannot be made to work, are quickly discarded by the INTJs.
To understand INTJs, their way of dealing with ideas should be observed closely. Their conscious thought is extraverted and empirical. Hence, they are better at generalizing, classifying, summarizing, adducing evidence, proving, and demonstrating than are the INTPs. The INTJs are somewhat less at home with pure reason, that is, systemic logic, where principles are explicit. In this respect they resemble the ENTJs. The INTJs, rather than using deductive logic, use their intuition to grasp coherence.
