Keirsey Character SorterAlong with the Keirsey Temperament Sorter questionaire, there are descriptions of the personality temperaments. Isabel Myers and Carl Jung each have different descriptions of the personality types, although there are many commonalities. David Keirsey has different descriptions from both Myers and Jung, but again with many commonalities. Dr. Keirsey's descriptions of temperament is based on the study of people and the study of psychology, including the works of Jung, Myers, Kretschmer, Spranger, Fromm, Haley, Bateson, etc. The brief descriptions on this web site are short versions of the descriptions in Please Understand Me or Please Understand Me II. Having identified your personality, it is suggested that you read the corresponding personality portrait in the in Please Understand Me or Please Understand Me II to decide how well or how poorly the description fits. The Keirsey Temperament Sorter, like all personality tests, is only a preliminary and rough indicator of personality. Please do not accept any personality test results without checking them out by watching people in action. People-watching will enable you to detect the difference between what people say they do habitually and what they actually do.
