Actually you're both retarded. Unless you've had them take the test, you can't really say what they qualify as at all. Even then, I'd want to see them take it enough times to the point where we can be sure that their type is correct beyond some chance. I don't even know how you'd begin to do that with something as fuzzy and illogical as MBTI.
MBTI's fundamental basis (Jungian functions) does not have any demonstrable basis in reality, so there's no real way for us to know whose type is whose at all. Not even your own. There's no real way to say that having a type predicts any set of behaviors either, at least I've never seen any research which tries to do that.
Ugh. This is like trying to argue over whether Odin or Zeus is more likely to exist.
