INTP I am

Being an INTP personality type, as the test I have taken has told me I am (literally, it spoke to me, called me names, just joking!), I am going to have to use my intuition in mentioning my name here, as it will be useful for people finding this this article.

Edit:

From what I've read on Similar Minds (elsewhere, and assumed), it's good to take multiple tests to find a more accurate result. So, I took a second test at http://www.humanmetrics.com/cgi-win/JTypes2.asp and received my personality type as "INTJ."

SOMETHING I DON'T AGREE WITH
While I would say I'm discerning, I wouldn't consider myself a judgmental person. I can tell the difference between two things very well, but I am very slow to judge because as far as what is ultimately good or bad (as judging implies to judge the rightness or wrongness of something "definitively"), I am not sure I know the ultimate truth of whether specific things are ultimately good or bad.
