With that being said, it is important to remember that INTJs’ Fi is in the tertiary position, which means it’s fairly unconscious.
One way in which Fi may influence INTJs’ relationships is by inspiring a sort of “savior complex” in the INTJ.
We’ve already seen how, as J types, INTJs are prone to seeing and diagnosing problems outside themselves.
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).
This is one reason why typology can be so useful for INTJs, as well as other types.
INTJs’ tertiary function is Introverted Feeling (Fi).While not necessarily their fault, this should comprise at least as much of their relational attention as trying to see and diagnose problems in their partners.To be fair, accurate self-evaluation can be a problem for all J-types, since their preferred mode of Judging (Fe or Te) is directed outwardly rather than inwardly.It is therefore important for partners to remember that INTJs’ first priority is accuracy of perception, so if the INTJ happens to be wrong, there is a good chance he will eventually come to recognize it.In order to compensate for such misunderstandings, INTJs might reason that if they could only understand people better they could overcome their relational difficulties.For one, INTJs with a history of relational difficulties can be prone to attribute those failures to psychological problems in their partners, thereby failing to see their own shortcomings.
