Myers-Briggs types versus Keirsey's temperaments versus Perseus system

The type descriptions of Isabel Myers differ from the character descriptions of David Keirsey in several important ways:

* Myers primarily focused on how people think and feel; Keirsey focused more on behavior, which is directly observable.
* Myers' descriptions use a linear four-factor model; Keirsey's descriptions use a systems field theory model.[4]
* Myers, following Jung's lead, emphasized the extraversion/introversion dichotomy; Keirsey's model places greater importance on the sensing/intuition dichotomy.
* Myers grouped types by ‘function attitudes’; Keirsey, by temperament.
