This doesn't have too much to do with being ENTP, but ut has more to do with it than burquas, so what the hell.
I read this post by simulatedworld and the main thing that it argues is that our functions is not a set of 8 tools that we use, but instead it is our values and motives for carrying out our actions. So to my understanding, an Fi and Ne dominant may both offer to go grab coffees for everyone, but they'll do it for different reasons. The Fi dominant will probably do it because he cares about the people and wants to make them happy, while the Ne dominant does it because he figures people are gonna bitch if he only grabs some for himself.
That article made a lot of sense. But I still have a few unanswered questions about the Jungian functions. I'm just going to list them.
1) Why do all extroverts have an extroverted dominant function? All an extroverted function means that your dominant function is focused outside of yourself. It does not, however, guarantee that you gain your energy from being around other people.
2) In the article he speaks of introverted/extroverted judgement/perception. Why is it that the T/F functions are considered Judging functions while the S/N functions are considered Perceiving functions? I have a general idea, but I still want to know a bit more about this.
