Though affable and sympathetic to most, INFJs are selective about their friends.
Such a friendship is a symbiotic bond that transcends mere words.
Writing, counseling, public service and even politics are areas where INFJs frequently find their niche.
Functional Analysis: Introverted intuitives, INFJs enjoy a greater clarity of perception of inner, unconscious processes than all but their INTJ cousins.
Just as SP types commune with the object and "live in the here and now" of the physical world, INFJs readily grasp the hidden psychological stimuli behind the more observable dynamics of behavior and affect.
Their amazing ability to deduce the inner workings of the mind, will and emotions of others gives INFJs their reputation as prophets and seers.
Unlike the confining, routinizing nature of introverted sensing, introverted intuition frees this type to act insightfully and spontaneously as unique solutions arise on an event by event basis.
