Hmmm… an INTP.

INTP (introverted, intuitive, thinking, perceiving) is one of the 16 personality types described by the Myers-Briggs Type Indicator (MBTI).

“People who score as INTP are often described as quiet and analytical. They enjoy spending time alone, thinking about how things work, and coming up with solutions to problems. INTPs have a rich inner world and would rather focus their attention on their internal thoughts rather than the external world. They typically do not have a wide social circle, but they do tend to be close to a select group of people.”

Not sure.
