Function Relationships
The attitude counterpart of Introverted Sensing is Extraverted Sensing (Se). Both functions work in the same broad domain, but one turns inward first and the other tests itself in the outer world.
The inferior counterpart often paired with Si in Jungian type patterns is Extraverted Intuition (Ne). This relationship is different from the attitude counterpart: it names the dominant-inferior axis that can become most visible under pressure.
