Seems kind of odd that a introverted-rational would be so against another introverted-rational function. To me, said function is more of a "there's that way (Role) to think of it, but there's also this way (Dominant). And I prefer the latter." That is, they're both based on some type of static system, but they source of them is different. Extroverted-irrational functions, on the other hand, are more related to objects in themselves, their potential or their state. That is why they make more sense (to me) as a Polr-function: they are not about understanding how things relate to each other, or a system, but about how things are. That is, Se or Ne are contrary to the concept of a system, to which Ti or Fi are related.
