The Myers-Briggs Type Indicator: Manual (1962).

Abstract

"This volume is the manual for the Myers-Briggs Type Indicator personality measure. The purpose of the Indicator is to implement C. Jung's (1923) theory of type. The gist of the theory is that much apparently random variation in human behavior is actually quite orderly and consistent, being due to certain basic differences in the way people prefer to use perception and judgment. "Perception" is here understood to include the processes of becoming aware,--of things or people or occurrences or ideas. "Judgment" is understood to include the processes of coming-to-conclusions about what has been perceived. If people differ systematically in what they perceive and the conclusions they come to, they may as a result show corresponding differences in their reactions, in their interests, values, needs and motivations, in what they do best and in what they like best to do. Adopting this working hypothesis, the Indicator aims to ascertain, from self-report of easily reported reactions, people's basic preferences in regard to perception and judgment, so that the effects of the preferences and their combinations may be established by research and put to practical use"--Book.
