Was that a conclusion you arrived to, based on everything you explained? Or did you start out by accepting it as true and then prove yourself?
Because to me it makes a lot of sense for people to be using the different functions (certainly to varying degrees) at different points having a select few preferences.
That's interesting, because this is a very Fi decision. Whenever you make a judgment, ask yourself what the ultimate root cause that led to it was. If you keep reducing, you'll find ethics and logic don't mix--one governs the inner world (and is thus subjective and non-negotiable) and the other governs the outer world (and is thus relative to current conditions.)
Posting in a MBTI forum for me is like going to sunday school when I was a child - even though I might agree with/believe in the theory/concept, I'm only interested in if it keeps answering the questions I come up with.
So what makes you think you're using Ti even some of the time? Fi "just knows" that you can't be so limited as to use only four of the eight functions?
I see it as : When you make internal value judgments based on your feelings, you're not using Ti.
Yes, and it's my (our) contention that Fi/Te people never make internal value judgments on any basis other than personal ethical values because they have a fundamental worldview that defines ethics as personal and subjective, and logic as dependent upon external conditions.
Provide any example you want where you think you used Ti, and if you keep asking "Why?" until it's reduced to its fundamental motivation, you'll find that it's based on subjective personal values (Fi) or an empirical definition of what works (Te.)
I see Fi and Te as a lot more contradictory between them than Fi and Ti which are basically using the same "work ethic", only with different objects. Now you can have preference for a certain kind of object (in an ENFPs case, feelings I guess) but nothing is stopping you for being detached in certain scenarios that don't strike you at a subconscious level (where instinct dictates that you WILL use Fi).
It may seem that way, but actually Te compliments Fi by providing a way to make impersonal judgments according to one's surroundings. Fi, being introverted, can't really deal directly with the external world so another form of judgment is needed to make decisions that require influence from external conditions.
The same relationship applies to Fe/Ti. Ti and Fi contradict each other because one says that internal value judgments should be made impersonally and the other says they should be made personally. If I were to ask you how internal value judgments should be made, you'd probably answer that it depends on the situation, but I think if you try and find a situation where you made an internal value judgment impersonally, you'll find that digging deep enough into your true reasoning process shows that it always reduces to an Fi value.
For instance, consider an INFP judge who is morally opposed to causing pain. Fi might prevent him from sentencing people to the proper punishments--but then (if he were a balanced person) Te would step in and say, "Listen, I know this feels wrong, but the system won't function the way it's supposed to if you don't do your job and sentence people to harmful punishments." You might misinterpret this as Ti, but it's really Te+Fi because failure to perform his duties correctly here would constitute an even broader breach of Fi's ethics--"It is my moral duty to pass this sentence."
It's all a question of whether you think morality comes from the inside and logic from the outside, or vice versa--and these are fundamentally pervasive worldviews that don't mix.
There seem to be quite a few INtPs out there which are a lot more comfortable with feelings, and it makes more sense for them to use Fi (which they seem to do, since they tend to be divided between the INTP and INFP descriptions) than to be using their inferior function Fe in any proficient way.
These are just people who don't know about functions and can't decide between the poorly written oversimplified MBTI profiles for INFP and INTP. There is a very distinct difference between the two in the way moral and logical values are discerned--but MBTI is garbage and doesn't tell you that. When Ti and Te get lumped together into just "T" and Fi/Fe turn into just "F", it's very hard to discern the difference between Te+Fi and Fe+Ti--but it's definitely there.
I don't know what makes you use the expression "large majority" which such decisiveness, but yes it makes perfect sense that my Fi's indignation at a possible threat to my individuality is the subconscious reason why I'm searching for a less constricting and rudimentary personality system that I don't think accurately separates me from other people.
I suppose I'd have to attribute this to my Si and its experience with this sort of thing. Ti users usually want to be placed into a particular category because they appreciate impersonal and definite categorization. Fi users (especially in conjunction with Ne) are almost invariably the ones who cling to "OH BUT I'M TOO UNIQUE TO BE CATEGORIZED, SO I DON'T HAVE A TYPE!!"...which is in itself a heavily Fi-oriented position.
Bear in mind, I'm not saying I'm not an ENFP, or even that I don't use Fi 90% of the time...I simply think I use Ti as well cause the description resonates..
And I do think that SOME of the conclusions I arrived to in my value system used Ti as well. Live and let live makes sense to me not just from an empathic angle but from a logical one as well.
Let's hear some examples of your Ti use. I expect upon closer examination they can be reduced to Fi/Te motivations.
Consider, also, that many descriptions of these things are poorly written by people who don't understand them very well. Often someone will notice a common behavior in INTPs and then write a description that declares it a Ti behavior, which is silly. There's no such thing as a Ti behavior, only Ti motivations.
