Such Irony,
I was not sure where to reply, since there are two threads.
I do not know, but we seem to be a lot alike, at least by the comparison between F and T in the other thread.
I posted over at INTPc for years, and I made a few threads like this one. There was not as much feedback! Of course, mine are maybe not so well written.
I'm currently considering that I'm INFP for various complex reasons. Yet, some people have convincingly questioned whether I was really NT, so now I'm confused again.
Yet, the F descriptions you mentioned all apply to me as well: (1.) sensitivity to criticism (2.) need for harmony (3.) need for praise (4.) sensitivity to the old man's firing.
I don't want to derail with my own questions, but I'm confused by the notion that the strongest function for INTP, Ti is supposed to be the weakest for INFP. And the opposite: Fi is supposed to be the weakest for INTP, but strongest for INFP.
Worse, I can of course skew the test. I can put on either hat. Also, it seems, I start asking myself, "What would an INFP or INTP say to this question?", when I post.
I go back through all my life, and I think I had lots of Fi moments and Ti moments. If a child is siting in a patch of clover alone, how can you tell if they are INTP or INFP? If they refuse to play with the other kids, then they are probably Introverted. This is from age 6.
If a child is playing a game, but looses all interest (or fun) once rules about the game are made, then I'd guess they are P.
Yet, it's difficult to say if they are F or T. It depends on what they are thinking, perhaps. I was trying to find 4 leaf clovers for my mom because she got excited when I found them. I guess the "F" is imagining her happiness, and seeing her press them in a book. And I guess the simultaneous Ti aspect is trying to find the best system for finding 4 leaf clovers. What is the correct angle of view? How can you mark where you've search or not?
Thus, even in one elementary school recess, I believe I see two diametrically opposed internal processes operating nearly simultaneously.
Anyway, I apologize for going off on a tangent about myself, but it seems the F and T question is difficult for me to answer as well. How can it even be answered?
I don't think the MBTI is true in some ways.
