1st: who you naturally are
2nd: what you naturally do
3rd: what you feel like you are "supposed to" do
5th: what you feel you are "supposed to" be?
6th: what you like to think or wish you are and feel stimulated when receiving it from others?
I think that if you score highly or think you are strong in both the introverted and extroverted of a function, like Ne and Ni, you may be looking at your 3rd and 5th functions. The 6th function can score high, but not in combination with the 4th. I think we resent that anyone may expect the use of whatever our 4th function is. Now... I'm told that the 7th or 8th function may test high... but I don't really understand how that's possible.
