There is but one problem with "understanding functions"...well its mainly my problem. I can't trust my understanding of it until I see examples and it is difficult to see to what % those ways of processing are actually mine. Stuff like this is a guess at best supported by scattered facts that keep changing/are not stable features.It's not really either. And its a really long explanation that gets at the core of Jungian psychology which you can explore more at http://personalitycafe.com/cognitiv...k-guide-understanding-jungian-psychology.html , but essentially the more conscious a function is, the more 'you' it is. So the reason we can safely call say an ENFP and Extraverted Intuitive is because they lead with dominant Extraverted Intuition. It's their default way of processing and dealing with the world and themselves. Now mind you this doesn't mean all ENPs will behave or act the same way. Quite the contrary people have all kinds of personas and social roles they adapt separate from their type. What type tells us is habituated preference. A way of processing that has become comfortable for us. The question you're asking isn't one that MBTI can really answer, but if you maybe get your feet slightly wet with Jung, you'll realize the greater implications of what he was going for when he wrote Psychological Types. Psychological Types - Wikisocion . In order to really understand it you sort of have to understand how he built the psyche and the role the functions play (and that the functions are not the sum total of personality, just one aspect of it).
All in all it is a highly problematic and inaccurate way of going about this...sadly we don't know any other ways -.- which is why after more then a year I'm still just maskarading as INFP and have no actual clue as to what type I actually am. My gut feeling just keeps telling me something is wrong with this theory.
