Okay so perhaps I'm nagging about this now but as different thinking occurs I post different things....
Right, an INTP who is forced to sort something out will engage parts of their shadow. It seems to me that in such a situation an INTPs thinking will closely match that of an ENTJ (if they can handle the situation).
An ENTP being definitive is very similar to an INTJ and an INTJ who is trying to be spontaneous with people is more ENTP.
I'm wondering what people think about such crude pairings.
My theory fits this model but I'm not sure if anyone else can see it or if there's other theories which are similar.
