Tertiary Function: Introverted Sensing (Si)

Si is a conservative function. It engenders a concern and respect for the past—for what is routine, familiar, or traditional. For INFPs, a full embrace of tradition can only emerge authentically after they explore it (and its alternatives) through the lens of Fi and Ne.

So even when a given tradition manages to pass muster, it is only after INFPs have personalized it and made it their own, interpreting it in a way that resonates with their deepest values.
