The study of personality type and temperament can be fascinating. In my admissions counseling work, I use the Myers-Briggs Type Indicator (TM) (MBTI (TM)) to assess high schoolers' personality preferences to see which direction in life may provide more happiness and success for them. By the way, if you're curious about which type you may be, try this little online questionnaire. It's not the formal MBTI (TM) instrument, but it will get you into the ballpark of knowledge about your personality type and temperament. Once you have your "four letters," you can then explore the Web for an almost limitless amount of enlightening data that will help you better understand yourself.
One of my many to-do projects is attempting to deduce the "personality" of certain colleges and universities. This may sound rather pie-in-the-sky-like to most folks, but I believe that if one looks deep enough, one can infer specific characteristics about a school's "attitude" and "preferences" to fit into the type and temperament matrix. Obviously, I haven't explored this project sufficiently enough to report any progress here, but when I do, you'll be among the first to know.
