This talk about Myers-Briggs reminded me of an old D&D survey that would generate your "character sheet" by asking you questions. Apparently it would use the game rules for things like holding your breath to figure your Constitution score and lifting weights to back-calculate your Strength, ethics questions to determine your alignment, that old outdated IQ test to determine Intelligence, etc.
I couldn't find it with a cursory Google search, but I remember being unimpressed with it. Literally: the real-world me is not an impressive D&D character. No magical ability, 10 or 11 in almost every stat, only proficient with medium armor (I've worn football pads before), two whole levels of Expert, that sort of thing.
