On the off chance that anyone cares, I've taken a Myers-Briggs thing, and it classified me as: Intraverted, Intuitive; Thinking; Judging -- Assertive. Or INTJ-A, also known as "The Architect."
Intraverted by a wide margin, and Thinking over Feeling also by a fairly wide margin, but the margins involved in the other three binary categories were smaller.
Apparently, people who like applying the Myers-Briggs test to fictional character have decided that this designation applies to both Professor Moriarty (in the Sherlock Holmes canon) and Dr. House (of the eponymous television series).
Do real psychologists still care these days about Myers-Briggs?
