I just don't get them.
How is there an IN, and further, an aloof INxJ, that uses auxiliary Fe? For whom Fe is a first backup option?
My understanding of Fe is that it's about relating to people and responding to them and to their emotions, it's caring about people, sympathising, understanding how they work, interacting with them, socialising, for want of a better word. I've seen it described as 'hosting'. Moreso than Fi, it orients your attention toward people, and the first thing you see when decision making will be the potential consequences a choice will have on people.
I'm having difficulty assimilating this with my idea of INFJs - based on little, if any, experience with the real thing, I'll admit. They seem like...they're detached from reality, and aloof, like INTJs, but they're (and this may sound very silly) serene and mystical and visionary, and also very rational. I can see Ni and plenty of Ti, and maybe Fi, maybe even Te, but I don't know about Fe.
Can someone in the know please explain INFJ Fe?
