You know..
The really ironic thing about these tests is that your reaction to it has a lot to do with your categorization. What I mean is that how you view the test, itself, is pretty fairly related to what you would score on it. Astrology is like this, too. Being an Aquarius, I see the truth in the astrology of all the signs, even if you don't think you represent your sign. Some signs are much more inclined to think the whole thing hogwash. Same with the Myers-Briggs and all the other tests. If you answer honestly, it does represent a large portion of who you are, but that also will reflect how you feel about the test results.
Anyway, INTP, here. (And Aquarius, and Tiger, if you like the Chinese astrology.)
