I think this thread throws up the general inconsistancy of MBTI in general, or perhaps of peoples understandings of it. Because once you start questioning your type or that of others, it does throw up a series of questions.
Are you right? Are others right? Which definitions on types and functions are correct or most accurate? Where is the objectivity?
If we give over to collective agreement that means you have no say, if we give over to individual assumption then everyone has a say; but with no solid footing to go off.
There should be a middle ground inbetween this that throws light on the information...but where is it? Where is clarity?
I cannot throw this idea in my mind that at some point MBTI and in fact Jung; was misappropriated or interpreted in a certain way and that this interpretation has caused a chain reaction of misunderstandings all down the line.
