What you describe sounds more like an attempt to classify aspects of the "Big 5" personality traits in some kind of binary system. Your "fact-based" persona seems to be low in agreeableness while the "story-based' is rather high in it (put very simplified).

"Story-based" would also correspond to "Intuition (N)" in the Myers-Briggs classification, while "Fact-based" corresponds to "Sensing (S)" (There is also some correspondence to "Thinking (T)" vs "Feeling (F)".

Yes, I know that Myers-Briggs rests on a shaky empirical basis, but it makes for a good narrative.
