So, we're all driving towards a good, objective understanding of the functions, but why don't we talk some about how the functions feel subjectively to each type. The reason I suggest this is because it can help with typing. For instance, I think this is a great description, taken from a review of the musical version of Sister Act, of how Fe (and, imo, alpha quadra) feels to an Fe-polr (imo, ILI):
"Call me a miserable old monk but I hated Sister Act. I hated its artistic laziness, its predictability, its incuriosity, its idea that disco is divine and that spirituality can never be found in discreet and dignified worship . . . I know I may be taking it too seriously but I found myself recoiling sharply from this story's saccharine values and its bullying gaiety. The thing is as shallow as the Aral Sea."
Point being, if we know how the IMs feel subjectively, then perhaps when people talk about certain environments/people/whatever, we can see how it correlates with having a certain IE in a certain position/function.
So yes, I don't have anything at the moment, but please share how you feel subjectively about each IM, how you experience it. Even if you know it is objectively wrong (i.e., "I experience Fi as a focus on manners and etiquette), share it, because if many people feel that way it could still be a good aid for typing, if not for actually understanding the core of the IM. Also, don't feel the need to address all 8; just talk about whatever you feel like talking about.
