People with INTP preferences use their thinking to find the principles underlying whatever ideas come into their awareness. They rely on thinking to develop these principles and to anticipate consequences. As a result, they are logical, analytical, and objectively critical. they are likely to focus more on the ideas than the person behind the ideas.
They organize ideas and knowledge rather than situations or people, unless they must for the sake of their work. In the field of ideas they are intensely curious. Socially, they tend to have a small circle of friends, and like being with others who enjoy discussing ideas. They can become so absorbed with an idea that they can ignore or lose track of external cirumstances
INTP's are somewhat quiet and reserved, although they can be quite talkative on a subject which they have given alot of thought. They are quite adaptable so long as their ruling principles are not violated, at which point they stop adapting. Their main interest lies in seeing possibilities beyond what is present, obvious or known. They are quick to understand and their intuition heightens their insight, ingenuity and intellectual curiosity.
Depending on their interests, INTPs are good at pure science, research, mathematics, or engineering; they may become scholars, teachers or abstract thinkers in fields suck as economics, philosophy, or psychology. they are more interested in the challenge of reaching solutions to problems than of seeing the solutions put to practical use.
Unless INTPs develop their perception, they are in danger of gaining too little knowledge and experience of the world. Then their thinking is done in a vacumm and nothing will come of their ideas. Lack of contact with the external world may also lead to problems in making themselves understood. they want to state the exact truth, but often make it so complicated that not everyone can follow them. If they can learn to simplify their arguements, their ideas will be more widely understood and accepted.
INTPs may rely so much on logical thinking that they overlook what other people care about and what they themselves care about. They may decide that something is not important, just because it isn't logical to care about it. If INTPs always let logic supporess their feeling values, their feelings may build up pressure until it is expressed in inappropriate ways
Although they excel at analyzing what is wrong with an idea, it is harder for INTPs to express appreciation. But, if they try, they will find it helpful on the job as well as in personal relationships.
