Introverted Feeling

INFPs live primarily in a rich inner world of introverted Feeling. Being inward-turning, the natural attraction is away from world and toward essence and ideal. This introversion of dominant Feeling, receiving its data from extraverted intuition, must be the source of the quixotic nature of these usually gentle beings. Feeling is caught in the approach- avoidance bind between concern both for people and for All Creatures Great and Small, and a psycho-magnetic repulsion from the same. The "object," be it homo sapiens or a mere representation of an organism, is valued only to the degree that the object contains some measure of the inner Essence or greater Good. Doing a good deed, for example, may provide intrinsic satisfaction which is only secondary to the greater good of striking a blow against Man's Inhumanity to Mankind.
Extraverted iNtuition

Extraverted intuition faces outward, greeting the world on behalf of Feeling. What the observer usually sees is creativity with implied good will. Intuition spawns this type's philosophical bent and strengthens pattern perception. It combines as auxiliary with introverted Feeling and gives rise to unusual skill in both character development and fluency with language--a sound basis for the development of literary facility. If INTPs aspire to word mechanics, INFPs would be verbal artists.
Introverted Sensing

Sensing is introverted and often invisible. This stealth function in the third position gives INFPs a natural inclination toward absent- mindedness and other-worldliness, however, Feeling's strong people awareness provides a balancing, mitigating effect. This introverted Sensing is somewhat categorical, a subdued version of SJ sensing. In the third position, however, it is easily overridden by the stronger functions.
Extraverted Thinking

The INFP may turn to inferior extraverted Thinking for help in focusing on externals and for closure. INFPs can even masquerade in their ESTJ business suit, but not without expending considerable energy. The inferior, problematic nature of Extraverted Thinking is its lack of context and proportion. Single impersonal facts may loom large or attain higher priority than more salient principles which are all but overlooked.

Always sceptical about this kind of thing, but that's me for sure.
