Fi is INTJs?
Look in their eyes. Its the look in their eyes that makes them look like they are always alone...
You have to look past the surface glare and it is there in every INTJ I have met.
I suspect i incorrectly translate and am incorrect in what they feel-but what I perceive is alone/hurt/desperation/pain and no kidding, I will hug the ones I work with. Because they need holding.
Fi in a good way gives them a deep sense of honor/integrity/stewardship, they seek protect those they care for. It can result in wisdom and great leadership.
immature Fi can make them a bit selfish. They will also incorrectly try and employ Te to problems where Fi would be a better fit, thus come up with odd resolutions to problems.
Fi gone bad is an Ni-Fi loop combined with context switching to resolve themselves of responsibility in a situation and subsequent never ending belittlement of the person they hate until the person dies. Good times.
A) Also-they are NiTeFiSe, thus their Fi is linked heavily to Se. They have a baby ISFP inside of them. They are Aesthetic Intellectuals. Thus they seem to experience Fi via Se mostly-via direct tactile/physical stimuli-seeing, touching, and holding. They dont seem to form deep emotional connections without this Se component-unlike an NFP.
B) Because Fi is linked to Se, their emotional judgments are linked heavily to the present moment. The most recent data points will outweigh any history in an interaction with another-Se is everything. An enfp will judge an emotional interaction with another over the entire course of that interaction-recent data points are compared to that history and considered anomalies if bizarre-Si is everything.
