I've been thinking that out of the cognitive functions that are judging functions (i.e. Te/Fe/Ti/Fi), Fi is probably the most useless in getting a job or having in work situations. Why? It seems to have no economic use! It's really difficult to bank on that function, because it seems that there aren't really jobs or careers for that function. I can't really come up with any real jobs that would pay money, that would necessitate or where the Fi function would be an advantage over Fe, Te or Ti! If Fe is sales, Te is management and Ti is engineering, what is Fi? This is a generalization, but helps to highlight the issue.
All the other judging functions are good at something that has economic value, but Fi seems to have zero economic value. Let me give examples. For example Te types have a tendency to be good managers, accountants and can be engineers (can use their Te strength). Fe types have a tendency to be good at sales, promotion and customer service (can use their Fe strength). Ti types have a tendency to be good engineers, especially electrical, electronics, mechanics and aerospace (can use their Ti strength)... It's difficult to come up with careers for Fi types... maybe arts, music, dance and such but really? Does Fi equal art?
However, I believe that the function has great advantages in private life.
I would love to hear what Fi dominants and Fi auxiliaries have to say (ISFP, INFP, ESFP, ENFP)!
