I noticed today that some people can pass as intuitive when they are really a sensor. My roommate is one example, and he's ESTJ, and has all the qualities of an ESTJ--doesn't like philosophy, likes simple things in life (don't take that the wrong way). But in conversation, he's like an intuitive. It's his third function:
Ne shares extroversion with Te, so when he extroverts, it seems it'd be easy to develop that third function too, perhaps even as well developed as Si.
Is it possible to develop your third function better than your second function? And do you find that it often happens?
