Most descriptions of introverted Feeling suck.
They’re either circular, truistic, or just plain wrong.
Circular definitions tend to say that introverted Feeling is about:
Feelings and values.
Many throw in beliefs for good measure, as if other cognitive functions are not about beliefs.
The “just plain wrong” category usually conflates feeling with emotion.
What is a value?
Value is an ambiguous term, so substituting “feeling” with “value” doesn’t clarify anything.
Values can mean “the things we place importance on”, but it can also mean “our standards or principles of moral behaviour”.
This latter definition leads to people drawing on specifically moral examples to illustrate how introverted Feeling works.
But Fi is not just about moral circumstances. I can use Fi to decide if a movie is a good movie or a bad one. That’s not a moral judgement.
What is missing from these descriptions is that introverted Feeling applies as much to objects, people, places, and events as it does to moral circumstances.
“Values” doesn’t really capture this. It’s just a partial synonym that people use because they don’t know how to define Fi more precisely.
And because they don’t know how to define Fi, they tend to focus on the negatives (like indecision, stubbornness), or entirely other-centred positives like empathy, caring, being a good listener, and so on.
Jung defined Fi
Jung describes Fi as a process that aims to find a kind of primordial image underlying external objects.
It is stimulated by objects, but then devalues them in search of a more intense vision.
This does apply to values and morality, but only because values and morality are a subset of things about which we can feel, and from which we can extrapolate ideal images.
But it’s more pertinent and more accurate to understand Fi in an everyday context rather than focusing on moral situations, which are already complicated by their very nature.
An INFP should have, for example, some kind of feeling for what an ideal library would look like, based on all their past experiences and observations of different libraries.
The ideal library is not a moral concept, and it’s not really a “values” concept either.
Instead it’s almost an archetypal image, and it is identified, understood, and assessed by the INFPs introverted Feeling.
You’re doing it constantly
The focus on values and morals exists because the INFP is most visible when they choose an unconventional path over a “moral” issue.
No one stops an INFP to ask them how their local library compares (feeling-wise) to the ideal image of a library deep in the recesses of their soul.
But for most of us, moral controversies are few and far between. It’s not enough to accept INFP descriptors based on other people’s observations:
Quiet, a good listener, has an unusual lifestyle.
It’s just because there’s such a thing as an ideal way to live your life, that INFPs are mistaken for simply having “strong values”.
