Got 59% INTP and suddenly had an epiphany. Basically, the best way to figure out whether you are an INTP is to check these parameters -
1) Depth of metathinking and depersonalization effect
2) Frequency of self-worth
3) Anal insistence on logical correctedness
4) Low conscientiousness
I easily got 94% INTJ because the questions were stereotypical, to begin with, INTP/INTJ. Telling them apart was not difficult. The philosophical questions also were stereotypical because both INTP and INTJ can take positions on the same things.
The only reason I may seem not INTJ is that INTJ tends to have a high IQ. Or for that matter INTP. They also tend to have big egos because they are right all the time (IQ again). Any INTJ that deals with problems because of low IQ would tend to be less confident. Unable to prove claims yet still think s/he is correct. And have goals they are unable to achieve. My softer side has quite taken over because my ego has been hammered down. The questions are a bit assholish.
