Which came first: MBTI/Jungian functions or the theory of MBTI/Jungian functions?
I guess I could elaborate with, "the general pattern seems to go that as people learn more about MBTI, the more faith they put in it and the more it reinforces itself in their minds and behavioural patterns, thus reinforcing their faith in the theory and its 'accuracy.'
So which came first: the theory that gave birth to these functions as an idea that people follow behaviourally (consciously or unconsciously), or the functions that hatched the theory because they actually exist to be systematically explained?"
If it is, indeed, the latter, then does anyone have any idea how we evolved to have the functions Jung claimed we have? I'm not talking about how each function helps us evolutionarily, but how it is we evolved into having certain behavioural traits that can be explained, simply, by a set of - what is it - 8 functions and their combinations?
Just a little speculation. Curious about what other people think...
