I've heard of some other type indicators, and I've seen a few floating around the forum, but the MBTI is the only one I know. Does anyone know about any other ones?
The big one is the "Big Five" or the "Five Factor Model". Can read a good overview of it at Quickstart and can take a decent version of the test at Twins! Introduction
Other models include; DISC, FIRO, PEN, 16PF, 15FQ, PI, MMPI and CPI... along with some specialty versions of others.

If this is the best of possible worlds, what then are the others?
