haha, my XSTJ is rather reflective, insightful, and fits pretty well with your definition, aj. He's really into new age thinking and the sort. But then again, some of his really good friends are INXPs.
However, I would agree with you that it is going to biased towards IN and to a certain extent EN.
EDIT: I am pretty sure he's XSTJ because he gets rather upset when the family breaks tradition like not getting a real Christmas tree, he went to school to be a commissioned military officer (very SJish), has a somewhat forced use of Ne, and gets irritated at people for not following directions.
