INTPs are pensive, analytical folks. They may venture so deeply into thought as to seem detached, and often actually are oblivious to the world around them.

Precise about their descriptions, INTPs will often correct others (or be sorely tempted to) if the shade of meaning is a bit off. While annoying to the less concise, this fine discrimination ability gives INTPs so inclined a natural advantage as, for example, grammarians and linguists.

INTPs are relatively easy-going and amenable to almost anything until their principles are violated, about which they may become outspoken and inflexible. They prefer to return, however, to a reserved albeit benign ambiance, not wishing to make spectacles of themselves.

INTPs are detached, analytical observers who can seem oblivious to the world around them because they are so deeply absorbed in thought. They spend much of their time focused internally: exploring concepts, making connections, and seeking understanding. To the Architect, life is an ongoing inquiry into the mysteries of the universe.

WHAT MAKES THE INTP TICK INTPs present a cool exterior but are privately passionate about reason, analysis, and innovation. They seek to create complex systems of understanding to unify the principles they've observed in their environments.

Their minds are complicated and active, and they will go to great mental lengths trying to devise ingenious solutions to interesting problems.

The INTP is typically non-traditional, and more likely to reason out their own individual way of doing things than to follow the crowd. The INTP is suspicious of assumptions and conventions, and eager to break apart ideas that others take for granted. INTPs are merciless when analyzing concepts and beliefs, and hold little sacred. They are often baffled by other people who remain loyal to ideology that doesn't make logical sense.
