I just took a half-assed Myers-Briggs type test. It still listed me as INFP (I=22%, N=56%, F=78%, P=67%), same as I got on the more complete test back in my high school days. I'll have to dig around and see if I can find a more complete test on the net to see if it says the same thing.
According to the informational blurbs following, only 1% of the general population shares my type. A. A. Milne was an INFP. So is Calvin of Calvin and Hobbes, if fictional characters count for anything. Yay me. Yay Calvin. Yay Pooh.
