Myers-Briggs type theory is a toolset for talking about personality and is based on the work of early 20th century psychologist Karl Jung.
This 
online Myers-Briggs test seems good as online MBTI tests go, but it's still nowhere near as comprehensive as the genuine MBTI instrument and even that claims only 85% accuracy. The individual is the best judge: if a description doesn't seem to fit, then it's probably wrong.

We're eventually going to graph this using a Gray Code single bit inversion, or something similar.
