yes, according to a lot of posts I've seen it sounds like Ti types are stuck blindly following rules meanwhile Te types are stuck mindlessly absorbing facts :/ which is sad
I think so, I took the word "static" in its literal interpretation but it looks like you meant it in context of theory, so we're on the same page here.
From what I understand their Ti definitions and categories are tied to some concrete variables while in Beta Ti is connected with some unified conceptual framework (Ni). That actually explains why I've observed Alpha NTs come up with theories and idea which they would treat as if they were something completely new, while for me it simply looked like a slight variation of an old concept. Then I'd become perplexed why they got all excited about it lol.
I've read Fi-valuers describing Fi as a sort of feeling of resonance or harmony when some information coming in from outside feels just right to you. The feeling of "coherency" that Ti gives I think is analogous to it. At least that is how I see it, once again basing from my premise that there is symmetry in this model. One big difference seems to be that while judging what resonates and what doesn't, Fi is striving to maximize the personal component while Ti is striving to take this component to nil.
I don't treat F functions as actual feelings per se because that doesn't seem to correspond to what can be observed of real people (i.e. types 'low' on F don't seem to be deficient on actual feelings or have lower feeling capacity, etc.) I mean it has been dubbed as "feelings" as per Jung but there seems to be some other modifier in effect here.
Sounds like NeFi. I cannot relate to this. I'm usually absorbed into my own thoughts, then at some point something might click together and it would just feels right though if somebody asks me to describe why it feels right I wouldn't be able to.
I've used the word "principles" in past as opposed to Fi "values" - some basic premises that on individual level one considers to be true - but that doesn't quite hit the mark either. "Rules" imho is a rather loaded term to use which can lead to misinterpretations in terms of actual behaviors that follow.
