I find it important, not to normalize MBTI. So according to the understanding, if some words a person says were really T or really F , it means that this is more to be applied in an interpersonal social complex.
So for example, when I tell a F in linear thinking that I will never watch a TV show again, because in a special moment it sucked and she replies "Oh you will". Then I know according to MBTI theory that this is because she sees things in a holistic manner and she knows that even if I say now "never", this does not mean that on the next day I will not draw a circle in my reasoning and watch the show again. What I wont, cause my T-ness is linear and when I say it, I mean it.
What I wanted to say: I do not think that personality psychology still works with intrapersonal mental disorders. You really can bend the theory to fit it and too see it as a holistic working system, because logically personality is made out of mental disorders. But linear spoken MBTI looses its charme in my opinion, when you apply it to medical issues.
It works better as an interpersonal concept, to establish connections between people, who otherwise would have never get to know each other, because they have no way of understanding each other.
Uff that post made me sweat, have to take a shower now
