One of the hallmarks of Fi is a desire to preserve and defend the uniqueness of the individual.This is why some INTJs (as well as IFPs) can seem fairly dismissive of or even hostile toward typology.Related to a strong concern for the individual is the Fi desire to aid the weak, helpless, and marginalized of society.This is why IFPs, for instance, can often be found helping the homeless, working with children with special needs, protecting endangered species, etc.As INTJs intuitively form impressions about the world, they naturally want to express them via their auxiliary Te.And because INTJs often prefer expressing themselves orally rather than in writing, they seek out others interested in hearing their knowledge and insights (they resemble INFJs in this respect). INTJs’ dominant function is Introverted Intuition (Ni).
Therefore, INTJs are generally less consciously concerned about Fi matters than FP types are.
This may inspire them to gather as many facts and self-help strategies as they can regarding human psychology and relationships.
While there is certainly nothing wrong with doing so, it may not always remedy their predicament in the way they might expect.
In fact, one of the primary reasons INTJs seek relationships is to have someone to share ideas with.
As David Keirsey put it, for INTJs, love often comes (and arguably should come) in the form of a “mindmate.” Unfortunately, finding a suitable mindmate is rarely an easy task for the INTJ.
