Fi is generally not complicated. It only appears to be complicated because Fi users tend to lack competence with the Thinking faculty. Thus, because they cannot explain even the most basic of things around them and in their inner life. Fi is also VERY ego driven, as it is in tune with our most personal aspect of the self or the sentiments directed towards our inner being. For this reason Fi users are often very busy giving themselves reasons to believe that they are great people.
For example, Roussaeu who has framed his cleaning lady for breaking a very expansive vase that he broke convinced himself he is a very warm-hearted person because the reason he framed the cleaning lady was because he had deep affection for her. He said she was the first person he thought of when he had to frame someone.
Fi's tend to lack logical reasoning skills and for this reason the reasons they come up to make themselves feel good about themselves are often inadequate.
The reason I maintain Fi is not deep or complex is because it is our thoughts that outline the structure of ideas we deal with. Feeling is merely an emotive valuation. For example, if I were to say, this vase is red. I am using Thinking, as I am describing the structure or the internal make up of an entity. Yet if I were to say this vase is red with a smile on my face, I would be adding Feeling to my statement, or simply a coloring. The aforementioned emotive valuation.
Fi's are deeply concerned with this emotive valuation, yet they often neglect their Thinking, therefore the true essence of things. Thus, when an Fi person feels they are deep or complex, they are merely confusing appearance for essence. They are judging a book by its cover, they are like a person who thinks the paintings of Rembrandt are compelling not because of the symbols he used to express his message, but because of the kind of colors, or how his canvas smelled. In other words, they confuse the mere coloring of the thing for the thing itself.
So, I must say, I feel no sympathy for those who deem Fi to be a grandiosely complex cognitive faculty. Those who judge for this to be the case are obviously suffering from a failure of rationality.

Introverted feeling is judgement with an emotional slant that causes the individual to view the object on a Subjective level. It is primarily a silent inaccessible function that is difficult to conceptualize. Therefore, unlike its extraverted counterpart, Extraverted Feeling, it is entirely individualistic, with a leaning toward the mystical. Introverted feeling is generally disconnected with typical external stimuli. Introverted feeling is only concerned with the external to the extent that the object has some relevance to a deep, internal value. Its primary objective is to harmonize ideologies, concepts, relationships etc. with the internal guiding force.
Whatever the individual values the most will dominate the motivations, goals and chief objectives of the individual. For example, if the primary value is God, then all other values will find themselves inexorably subjugated to this primary one. Often, unbalanced introverted feeling will create in the individual dramatic mood swings and decisions based on illogical rationales. However, at its best, introverted feeling provides a navigational quality that creates in the personality tenacity, idealism, honor, relationship wisdom and a unfaltering value system that is seldom compromised.
Jack, you're claiming that someone, like Emeinem (or however you spell it!) would fake Fi for a whole freaking career, build their life's work on something not natural to them. I admitted that they might do a special work every now and then but the body of their work would reflect their preference functions. I just don't buy that the body of their work would be based on a unconscious function.
