Horse before the cart. Got it. The cognitive function (Ni, Ne, Ti, Te, etc) and/or dichotomy (I/E, N/S, T/F, J/P), produces a temperament (Rational, Idealist, Guardian, Artisan), and that temperament requires discernment as to it's cause, and could almost be any type I'm thinking. I was having a discussion about Martin Luther King Jr., and the suggestion was that he's an ENTJ, the bold leader type, (probably 8w9), and it makes sense, even though everyone who uses temperament to type, puts him in the idealist camp as some ENFJ, INFJ, ENFP, when he might very likely be a highly idealistic ENTJ rational, that just uses NF ideals to lead.
Am I on the right track?
