Personality Types…
Tuesday, July 22nd, 2008Recently for my principals program we all took the Myers-Briggs Personality Type Indicator, which divides people into 16 different personality types based on four dichotomies (extroversion / introversion; sensing / intuitive; thinking / feeling; judging / perceiving; ie, some possible personality types include INTJ, ESFP, etc). [Sidenote: That link is to a free, abridged, but reliable version of the test; if you want to pay $30 for the full version plus a bit of analysis, look here. You can also take a type test for programmers here, though why programmers need their own special kind of instrument, I have no idea.] The purpose was twofold — a) to understand why meetings are hard sometimes, & b) to understand the ramifications for each of our individual leadership styles.
Being an amateur psychologist, I love this kind of stuff. Was it enough for me to just take the test & read the results? Noooooo! No, I had to read the full results for all sixteen personality types, plus the entire Wikipedia page on the instrument itself. Then I had to retake the test several times to see if I got the same results.
And I learned a lot of interesting things. For one, for all that the validity of the test (& Carl Jung’s work on personality types in general) has been questioned at least as much as it’s been championed, its reliability is supposedly pretty darn good. (Amateur psychologist / mathematician translation: From a scientific point of view, the test is definitely testing something about people that seems fairly immutable. Whether that something is really personality type, Myers’ & Briggs’ work on personality is correct, or any of it is of any practical use to anyone is not entirely clear.) (more…)
