Personality of a Prof

In an earlier posting called Personality Matters I promised to check with some of my old professors and find out their personality type. This was to check the assertion by Borg and Shapiro that:

the closer the match between the temperament of the
student and the instructor the better the final grade of the
student.

One of my old professors wrote back and told me that he is an INTJ. I am an INTP. I got an A in both of his classes.
