Despite being Fi dominant, my Fe overrules Fi all the time. "The needs of the many outweigh the needs of the few, or the one." Ironically, I know this is because my Fi demands it.
But I have been pondering the difference between the two functions. Mostly thinking of the misapplication of each, hence the post title.
Fe blindness: interchanging your own needs with the needs of the group. This means that sometimes the group needs become yours, and sometimes, you allow your personal needs to be applied over the group, because you have an agenda you want to fulfill. In other words, you trick yourself into believing you are doing something for the good of the group, but it is really what you WANT. And you violate the needs of the group to do so, all with a pretty veneer applied over top to make it look like the needs of the group are what you are working for. And, YOU can even start to believe it yourself, that you are only doing what is good for the group.
Fi shortsightedness: you feel your feelings, but you apply them over top of what you perceive from others. Example: let's say you're angry with person X because you've been done wrong, so you allow that anger to colour all of your interactions with person X and thus you lose prized objectivity in your relationship. It takes a great deal of personal power to step back and not allow your own feelings to cover you. Alternatively, you feel others feelings, and you misinterpret them as your own, finding it hard to unweave what you own vs what other people own or are trying to blanket you with.
Just some thoughts this morning; discuss, refine or disagree if desired.
