Data ("data"?) point: I test reliably as NF (ENFP, specifically) and SaidAchmiz's objections seem quite similar to my father, who is clearly (by both of our estimations, and tests) NT (INTJ). I can think of another relevant person, who tests as INFP and seems to be at pains to encourage interaction, and yet another who is also ENFP and similarly tries hard to encourage interaction. So I was rather surprised to see you painting SaidAchmiz's objections as non-NT.

My current model suggests that what I am promoting is F values (possibly NF, but I don't know any SF's well enough to compare) with an extraverted slant

(but not as much of an extraverted slant as SaidAchmiz seemed to think, I agree that even if at the time being drawn out of ourselves is an unpleasant experience, everyone, extraverted or introverted, gains something of real worth if they really attain that level of self-detachment regularly.)
