As a Tertiary Function
, Fi typically leads ITJs to retreat into solitary actions that have no constructive worldly effect but are aimed at providing a justification for calling themselves good people. Another example is obsession with the purity of one's soul. For example, being a vegetarian while working at Taco Bell--not out of any great love for animals (the person might hardly know anything about what cows are like), but to be able to say, "Well, at least I
never ate any animals." Or engaging in pointless acts of honor, like maintaining super-self-control or "doing one's duty" or going down with the ship. Nothing is gained by going down with the ship; it's a hyper-introverted
act aimed at providing a rationalization for one's goodness without regard to real-world consequences. Nearly all of these tertiary-Fi acts involve refraining
from action viewed as unethical rather than taking positive action that would accomplish something. They're a retreat from the world--or rather, a rationalization for disregarding worldly matters.
