I read this thread and keep seeing this pattern. I really think you guys are giving Ti the credit of what is actually an internal process dominated by Ni, with Ti supporting. Ni, in my opinion, is a lot like thinking, but more about the patterns (skme crap about unconscious free-association). Ni is a type of thought. I'm not saying you're all wrong, but it just seems incorrect that so many of you claim to have a Fe so underdeveloped that your Ti is somehow more developed? Just because math is so left-brained, doesn't really mean that it's pure Ti at work. Math is about patterns and ideas, and only in high school is the redundant step-by-step shit applicable... and fuck high school. My hatred of high school isn't what I'm trying to get at, what I want you to consider is this. The introverted functions are frameworks for different ways of dealing with things. The Ni is a blueprint for thinking about patterns and such in a ore "meta" way, and is built up over time with info unconsciously collected by Se... I would call it "same thing as Ti, but unconscious," however I now realize that is not fully incorrect. Ti is a framework for problem solving in a logical and orderly way, and so is Si. There's a difference between Si and Ti which is hard to describe, one is more applicable to physical reality and "useful," that's Si. While Ti is more objective and critical. Fi is a framework for sorting through feelings... But I'm pretty out of touch with that. Another point, you don't know what it's like to be a Ti-dom like ISTP, not Fi-dom like ISFP, and not Si-dom like ISTJ. You are likely Ni-dom (if INFJ) so it's hard to say what's what and what isn't what and whatever and so fourth... Ni is supported by Ti, blurring the line between unconscious association and its conscious realization. I often say I solve math problems more so with intuition than thought (and I'm often wrong and have to go back and do it step-by-step... hate high school).
I'm just an 18 year old dude going on a tangent now... completely exhausted from the past two days, haven't slept for about 30 hours and am probably not really communicating anything coherent right now. Fookin ell it's time to pass out. Good night all (Fe).
