I'm running on time, so this isn't the best description of beta Fe.. anyway.. Some misunderstand Fe as merely visible emotion and enthusiasm, when it's not. In essence betas are seen as the most dramatic aswell as the epitome of romantic for preferring close focused intimacy & maximum intensity of feelings, whether negative OR positive.
From Sir Night's post "(- Fi) means that i'm willing to cut out negative relationships and I'm willing to remove myself from relationships that do me little good. That however, is very subserviant to (+Fe), the desire to enjoy the breadth of emotional experience."
We are inclined to display but don't attach much meaning to general social norms & niceties (- Fe). And, whilst understanding the inherent value of universal love, or humanitarianism (+Fi) it's not seen as serious concern. Managing the negative qualities of relations isn't the main concern of course, it's done when it doesn't contradict the emotional impact.; So, (-) is only valued in support of (+)..but wouldn't you agree it's obviously valued?
Model B has gr8 unappreciated significance.
