That's really interesting, thanks for posting it.
I had no idea my Si and Se were so strong, they feel oddly natural for me (although I know I couldn't keep them up for very long periods of time). I knew Ne and Ti were going to be at the top, and this confirms it (they are extremely natural for me). Ni I also expect to be relatively high (I've done the thing in the exercise numerous times). And dang... apparently I was overestimating my Fi, because I don't naturally do that much at all (except on myself, hardly ever for others). I'd be willing to say my Fe is somewhat higher than my Fi now that I understand the difference. So maybe I am more like a typical XNTP (whatever that is) after all?
Brain, I think you're XNXP. (Or at least that would come closest to describing it).
