I'm surprised to read many thinking of ENTJ as the pure rational. It's not an offended, it's more of a compliment for my type, but I'm not sure if I'm deserving. I'm quite rational with most everything, but I embrace the subjective, personal desire, personal will, wants, want-nots.
Okay, my world view is perhaps less twisted to serve just my intentions than that of the most people, but in my book, INTP is the incarnation of rationality, sometimes to the point where it isn't serving him fully. OTOH, perhaps INTP is SP-like in their tendency to just enjoy doing their favorite activity.
Or, is INTP NF-like? They seem to think it's the best way of life to engage in intelligent thought, and live their ideal of life. Could it be ENTJ who are the most SP-like of rationals? From what I see, they seem to embrace life quite fully, like ENTP.
Here's my list, compiled from personal feelings on the subject, not according to any formula.
