well I don't try to think about it. It just happens. Nothing else to think about I guess. (I'm using four subscripts for each function now o.o, wayy over thinking. INFJ = Nijdf-Fepan-Tijds-Sepat). dom and ter elements are directive, aux and inf elements are adaptive, the j/p is analogous to J/P-dom, just as i/e is analogous to I/E). Functions are then also classed by what function they naturally conjur up, e.g. INFJs Ni has a natural F quality to it, because it is designed to flow in real time into F.)
They would maybe be XXXX in the sense that each usual dichotomy is equally represented on some level. However, at the level of real world interactions the usual dichotomies do get stressed, so this doesn't even matter. They still only access half of the function subtypes, the others are covered/unconscious.
