[MENTION=3710]AlienSpectator[/MENTION] Have you ever read L'Etranger (The Stranger) by Albert Camus? The main character is just that, a spectator (though he's also disconcertingly apathetic, which I doubt you are). And I did, personally, find the book to be very dull, so maybe you're right.
EDIT: Wait, he'd probably fall under the category of "too cold"... NVM.
I freaked out reading the books because it seemed to me like he was using a whole lot of Ni. But I still don't completely grasp the individual functions, so maybe I'm wrong. The way he described every seeming intuitive leap as having a logical reason, seemed like "conscious Ni" to me, which got me really excited. It's like, instead of having the answer immediately jump out at him with no idea how he reached it (which is how Ni usually operates, at least that's my understanding of it), he's able to consciously process all the clues that lead to the answer. Super Ni? Learned Ni? I don't know, but it's awesome!
Would you say Sherlock Holmes is an INTJ?
