Approximately 12-15 percent of the general population are introverted feelers (IF), a temperament type that is subjective and, according to Jung, “continually seeking an image which has no existence in reality, but which it has seen in a kind of vision. It glides unheedingly over all objects that do not fit in with its aim. It strives after inner intensity, for which the objects serve at most as a stimulus” (Psychological Types, para. 638).
The depth of this feeling can only be guessed–it can never be clearly grasped. It makes people silent and difficult of access; it shrinks back like a violet from the brute nature of the object in order to fill the depths of the subject. It comes out with negative judgments or assumes an air of profound indifference as a means of defence. The primordial images are, of course, just as much ideas as feelings. Fundamental ideas, ideas like God, freedom, and immortality, are just as much feeling values as they are significant ideas. Everything, therefore, that we have said about introverted thinking is equally true of introverted feeling, only here everything is felt while there it was thought. But the very fact that thoughts can generally be expressed more intelligibly than feelings demands a more than ordinary descriptive or artistic ability before the real wealth of this feeling can be even approximately presented or communicated to the world. If subjective thinking can be understood only with difficulty because of its unrelatedness, this is true in even higher degree of subjective feeling. In order to communicate with others, it has to find an external form not only acceptable to itself, but capable of arousing a parallel feeling in them.
Thanks to the relatively great inner (as well as outer) uniformity of human beings, it is actually possible to do this, though the form acceptable to feeling is extraordinarily difficult to find so long as it is still mainly oriented to the fathomless store of primordial images. If, however, feeling is falsified by an egocentric attitude, it at once becomes unsympathetic, because it is then concerned mainly with the ego. It inevitably creates the impression of sentimental self-love, of trying to make itself interesting, and even of morbid self-admiration.
Just as the subjectivized consciousness of the introverted thinker, striving after abstraction to the nth degree, only succeeds in intentisfying a thought process that is in itself empty, the intensification of egocentric feeling only leads to inane transports of feeling for their own sake. This is the mystical, ecstatic stage which opens the way for the extraverted functions that feeling has repressed. Just as introverted thinking is counterbalanced by a primitive feeling, to which objects attach themselves with magical force, introverted feeling is counterbalanced by a primitive thinking, whose concretism and slavery to facts surpass all bounds. Feeling progressively emancipates itself from the object and creates for itself a freedom of action and conscience that is purely subjective, and may even renounce all traditional values. But so much the more does unconscious thinking fall a victim to the power of objective reality.
Jung continues to discuss the introverted feeling type (IF) by stating that this type is often silent, inaccessible, hard to understand, hides behind a childish or banal mask, and is inclined to melancholy. In fact, as many as 65-85% of people diagnosed with major depressive episode are introverted feelers. Introverted Feelers value peace and harmony above almost anything else; strong emotions are struck down “with murderous coldness” or nearly paralyze the IF. In women, especially, introverted feeling tends to come off as cold because the strong feeling component is introjected rather than sent outward by projection onto others. In pathological introverted feelers, there is a tendency to overpower or coerce others to get one’s way, “in the form of a domineering influence often difficult to define” (para. 642). Introverted feeling women tend to attract extraverted men, for their power touches the unconscious in the man.
