No way, he wasn't one of us!

I've never yet heard of an INTJ who starved himself! Doesn't that go contrary to our "hidden agenda?"

I'm sure he was an INTP. An "ultimate" INTP who had a talent for completely losing himself in abstraction, but an INTP nontheless.

...It's remotely possible that he was an xxxP (incarnate perception), but I can't vouch for it because I haven't had enough sampling for my test. He wasn't the kind of guy who liked to be around other people though, so he doesn't seem that narcissistic. I still think he was an INTP.

INTJs don't have that kind of patience for math.
