Also, this may be way too highly based on stereotype. But due to my categorizations of the types and how I view them based on functional stackings and descriptions creating certain images/characters in my mind, and some people I know with likely accurate typings, my entire understanding would become f*cked if I were actually a different type. That's practically unthinkable for me, since I usually am able to assess people accurately and then their viewpoints and actions follow through from there. If my understanding of the system is wrong in such a major respect as myself, (since I introvert first, looking inwards, draw conclusions there and then project it outwards and apply the system to external things) I wouldn't know much of what to do with it anymore. Basically, if I'm not INTP, in all the strange things I do and conceive of that I believe fit the stack, then I don't even want to know what an actual INTP is like... Must be horrid, or something.
I certainly don't think of them that way as they arise, it's just whatever's enjoyable or worthwhile. <- Wow, evaluating the worth of something, such Fi. I've considered INFP plenty, as a close contender to INTP. My understanding of Ti and Fi are quite blurred, as Ji basically stands out as making decisions based on one's personal notions and understandings. However, I don't really "get feelings." It could be postulated that my Fi is so inherent/natural at this point that I don't notice these things. As far as I can tell though, the way that I go about things and how I conceive of them, what attracts me, is all quite Ti-oriented. I've only had descriptions of INTP, INTj, ENTP, and ENTp be spot on enough.
