After more thought, I think badgoodDeb has hit on an important truth: I like to read stories with main characters who are introverts more than stories with main characters who are extroverts. Wow, deep insight!
In thinking through the other Briggs-Meyers scales and the books I like best, I probably also prefer characters who are (or grow to become) "perceptive" rather than "judgmental," but not as strongly. The other two (T/F, S/N) are more of a wash, probably because I don't align so strongly on those two scales.
This would explain why I like Pratchett's witches better than his wizards, too.
