Scientific breakthroughs
INTPs live in a world of theoretical possibilities. They see everything in terms of how it could be improved, or what it could be turned into. Many scientific breakthroughs in the world have been made by INTPs. The INTP personality type is at his best when he can work on his theories independently. When given an environment which supports his creative genius and possible eccentricity, the INTP can accomplish truly remarkable things.

Live within their own head
They may seem dreamy or distant to others because they spend a lot of time inside their own minds. They have a strong ability to analyze problems, identify patterns, and come up with logical explanations. They typically are so strongly driven to turn problems into logical explanations that they live much of their lives within their own heads, and may not place as much importance or value on the external world.

Extremely bright
Like INTJs, INTPs value knowledge above all else. They approach problems and theories with enthusiasm and skepticism, ignoring existing opinions to define their own approach. They are usually extremely bright and able to be objectively critical in their analysis. They love new ideas and become very excited over abstractions and theories.

Tolerant
INTPs do not like to lead or control people. They’re very tolerant and flexible in most situations unless one of their firmly held beliefs has been violated or challenged, in which case they may take a very rigid stance. An INTP is likely to be very shy when it comes to meeting new people, but will be very self-confident and gregarious around people they know well.

Not in-tune
The INTP personality type holds little value for decisions made on personal subjectivity or feelings. They strive constantly to achieve logical conclusions to problems. Because of this, they are often not in-tune with how people are feeling, and are not naturally well-equipped to meet the emotional needs of others.
