Is There a Superior Function?

You say that whether one is introverted or extraverted only becomes apparent in association with one of the four functions. Each of which, as you explain, has its own special area of expertise. And personally, it's the best model i know for understanding myself and others. Yes, a yo compared his model to a compass, noting that he would not for anything dispense with this compass on his psychological voyages of discovery. But all four are not equally at one's conscious disposal. They're not uniformly developed or differentiated. That one tends to be more developed. Right?
