According to the Myers-Briggs Type Indicator, the most common personality assessment tool, your character is an Introverted iNtuitive Thinking Perceiver type (INTP). Click here for a copy of your answers to the questions, and click here an on-line version of the MBTI itself.
The INTP type, also called the solitary or scientist type, is marked by an intensity of thought to the point of detachment, a fascination with systems and logic, and a desire for logical correctness with a constant fear of incorrectness.
In line with the INTP type as a whole, your intensity of thought and practice often overwhelms your awareness of that which is around you. You have a haunting sense of impending logical failure, and spend a considerable amount of time second-guessing your decisions in order to avert this failure. The type's combination for open ended thought (from Perceiving) and need for competence (from iNtuitive and Thinking) often leaves you with a sense that your conclusion might have an equally relevant alternative solution, that you have overlooked. Thus when you are arguing a point, you are often trying to convince yourself as much as the other person(s).
Another key INTP trait is your obsession with complex systems. While most INTPs tend towards math, languages, and computers, you tend toward cultural and art historical systems. You approach them as a logic to explore, with a concentration that excludes all outside stimuli until the task is completed.
