Has anyone read this:
(If anyone knows where I can find a human translation of this, that'd help.)
It explains the difference between extraverts and introverts.
The thing that really got me was about how extraverts see things in terms of subjects/objects while introverts see the relationships between said objects.
So when things don't add up, the extraverts use their introverted second functions to change the relationships to fit the objects, and the introverts use their extraverted second functions to change the objects to fit the relationships. Hence the second functions being creative.
(Someone who knows more about this, tell me if I understand it correctly.)
