Funny that people are asking for vibes whereas they deserve a kick in the head.
I have a question based on XNTPs, but applicable to other types too, I'll probably work out the answer while writing it (as usual). For an INTP, does Ti present itself to the outside world in any way? When interacting with others socially, do they sort of have to extravert their dominant function, or do they simply rely on their secondary function?
I know an ISTP who has once before explained how *something car related* works in exquisite detail while we were talking, so I'm assuming that Se doesn't really get 'extraverted' or adjust to the situation, but has a more preferential influence on thought.
I pose the parallel question for ENTP, and really all other extroverted types.
Actually, I don't think I'm thinking through this the right way, extroversion/introversion is more of a preference, right? So then an ENTP would be capable of using Ti and Ne in any given situation, but they have a preference (or a 'taste'

) for Ne (and a preference usually comes hand in hand with a strength). Which then results in naturally seeking out possibilities and patterns in the outside world and then breaking them down using Ti. So, when talking, it's most likely that the ENTP type will conjure possibilities, and then crunch them internally as they go using Ti (Which come to think of it, is EXACTLY what I'm doing now). So there's no reason to revert to Ti when introverting, and no reason for an INTP to revert to Ne when extroverting, as each type has it's own thought process. So when talking to an INTP, they will internally think through the logic, and then... well, apply Ne somehow, probably by considering another possibility, which really has quite a perceiving taste to it doesn't it? But shouldn't it require Ne to feed the internal logic with at least one possibility?? I guess that is still a Ti preference, regardless of where it starts, that makes sense.
I would think that the difference between INTP and ISTP then, would be that the leap between possibilities would be dependent on Ne or Se, for an ISTP, they would likely make a concrete transition, progressing from one piece of information to the next (in the sensing fashion), whereas an INTP might see a pattern emerging and intuitively jump to where they think the solution might be, which explains why intuitives are solution orientated and sensors are more focused on procedure.
Yeah, I answered my own question, and have solidified my understanding of MBTI, and I accidentally confirmed that I'm an ENTP... which I've been trying to do for months without any definite solution. Such a joyous moment, ummmm... thanks blackcat???
edit: Actually, by my definitions and etc. I don't think I've quite ruled out INTP, I seem to start with a question produced by Ne, then apply Ti, which doesn't necessarily mean that I prefer Ne or Ti, it just means that I'm using them. Theoretically, an ENTP would spend more time questioning and coming up with ideas than breaking them down, which is why they move through topics so quickly. So really, I need to ask myself whether I prefer to, or perhaps find it easier to, summon up ideas, or break them down. I hear that you naturally use your dominant function without applying much effort, and then consciously apply your secondary function. I'm fairly certain that I'm consciously applying Ti, grinding the possiblities down, which I don't always do, I'm much quicker to ask questions. Okay, problem solved (despite not even setting out to solve it in the first place

)
I still have one more question left for you: Does my... well, I think you could call it a 'system', work for Fi in some way? I still haven't touched on Judgers either. Do other people understand things in the same way that I just did, or do they all rely on profile descriptions and books?
