Scroll down to the test, follow what it says, calculate, see your designation and match it to the text above.
My results were:
Your type: INTP
Introvert 82% 18% Extravert
iNtuitive 73% 27% Sensate
Thinking 96% 4% Feeling
Perceptive 84% 16% Judgemental
Turns to this:
It's... pretty accurate so far, though time will tell.iNTp: Architect
Of the four aspects of strategic analysis and definition it is the structural engineering rolearchitechtonicsthat reaches the highest development in INTPs, and it is for this reason they are aptly called the "architects." Their major interest is in figuring out structure, build, configurationthe spatiality of things.
As the engineering capabilities the INTPs increase so does their desire to let others know about whatever has come of their engineering efforts. So they tend to take up an informative role in their social exchanges. On the other hand they have less and less desire, if they ever had any, to direct the activities of others. Only when forced to by circumstance do they allow themselves to take charge of activities, and they exit the role as soon as they can without injuring the enterprise.
The INTPs' distant goal is always to rearrange the environment somehow, to shape, to construct, to devise, whether it be buildings, institutions, enterprises, or theories. They look upon the worldnatural and civilas little more than raw material to be reshaped according to their design, as a formless stone for their hammer and chisel. Ayn Rand, master of the Rational character, describes this characteristic in the architect Howard Roark, her protagonist in The Fountainhead:
He was looking at the granite. He did not laugh as his eyes stopped in awareness of the earth around him. His face was like a law of naturea thing one could not question, alter or implore. It had high cheekbones over gaunt, hollow cheeks; gray eyes, cold and steady; a contemptuous mouth, shut tight, the mouth of an executioner or a saint. He looked at the granite. To be cut, he thought, and made into walls. He looked at a tree. To be split and made into rafters. He looked at a streak of rust on the stone and thought of iron ore under the ground. To be melted and to emerge as girders against the sky. These rocks, he thought, are here for me; waiting for the drill, the dynamite and my voice; waiting to be split, ripped, pounded, reborn, waiting for the shape my hands will give to them. [The Fountainhead, pp 15-16]
Many regard this attitude as arrogant, and INTPs are likely, especially in their later years, after finding out that most others are faking an understanding of the laws of nature, to think of themselves as the prime movers who must pit themselves against nature and society in an endless struggle to define ends clearly and adopt whatever means that promise success. If this is arrogance, then at least it is not vanity, and without question it has driven the design engineers to take the lead in molding the structure of civilization.
