The concept of "temperament" has been one of the toughest ones for me to get my head around

I feel things in common with IEEs the most - ILEs and SLEs are tied for second, and for very different reasons - I can't think of much all three of them have in common with each other, or how much any member of a temperament pool has in common with an averaged idea of the whole thing... I don't see enough commonly shared values, ideas, behaviors, patterns, etc., for that matter, to take the concept of temperaments with much weight (as of yet, at least), at least when compared to quadras or cognitive style Supervision rings...

When I look at it on paper, the only dichotomy universally shared within a temperament, outside of the two that are explicitly stated in the temperament itself, is Static/Dynamic (and it's just as well as stated there ), and I expect even more looseness in Irrational temperaments due to around half of the people in them having a type of F as a Creative function...
