Yes, OP, I am definitely inclined to agree with you. (But maybe not so feverishly.) I don't always understand the use for Ne Fi, and feel that I am always "working on something" about myself. Trying to balance it out somehow. I guess that's part of the combo though, values and possibilities is going to lead the person to attempt to be more and possibly forget who they actually are.
I don't think intelligence is always classical NT sense. Though, they do have a certain thought process that is like, "wow! Why didn't I think of that???" But, IQ test wise-.... we all have certain abilities to figure things out, we just all come from different directions. Also, haven't you ever noticed the value in being charming? I can say what I feel has been the most harsh, rude, or ridiculous thing, I can get away with murder and somehow always remain popular and well accepted. (As shallow as this sounds on paper, it is extremely important in the world- it helps us navigate easily without having to do much legwork.)
The beauty of Ne Fi is just adaptability. It sounds so soft. Being kind of a mirror reflection of everything around you, but it definitely has it's value- it's just hard to see the value when you are living the situation. It just feels so fuzzy and non-descript. Our logic is fuzzy, our speech is fuzzy. The other cool thing about this chameleon combo- is that we can literally pick up and adopt any mentality we want to, and that translates into doing almost anything we want to. Except for maybe doing the taxes or showing up on time. But THAT'S BESIDE THE POINT.
