I don't know if I agree with this assumption despite its commonality in MBTI forums (haven't seen it used in socionics forums as much). I also don't see the necessity for it, unless, of course, it's a logical consequence rather than an assumption. But I don't know what axioms are present in socionics to allow for such a conclusion - I am generally unaware of socionics' epistemology. Anyways, I have to think more about it before concluding anyways. But that's besides the purpose of the thread.

I got INTP on most tests for the last 25 years most the time. My ISFP phase was just a desperate midlife cry for much needed Si and Fe. I'm married to an ESE now who gives it to me and helped me return to my normal self.
Do you mean INTj (LII), or are we talking about MBTI (many INTPs type as LII, though it shouldn't be used as a translation)? You use ISFP later, which I assume is ISFp since you typed yourself SEI before. It's good you've managed to discern differences between what your nature is and what you need at a particular moment in time. Good for introspection and understanding yourself.
