Carl Jung's Psychological Types (1921) The story begins with Swiss psychiatrist Carl Gustav Jung, who published 'Psychological Types' in 1921. In this landmark work, Jung proposed that human behavior is not random — it follows recognizable patterns rooted in how people prefer to perceive the world and make decisions. Jung identified two primary attitudes (Introversion and Extraversion) and four functions (Thinking, Feeling, Sensing, and Intuition), which could combine to create eight distinct psychological types. Isabel Briggs Myers and Katharine Cook Briggs Inspired by Jung's work, Katharine Cook Briggs and her daughter Isabel Briggs Myers spent decades researching and developing a practical psychometric tool based on Jung's theories. During World War II, Isabel was motivated by a desire to help women entering the industrial workforce for the first time find roles that suited their personalities. By the 1940s, the Myers-Briggs Type Indicator (MBTI) had taken shape, and it added a fourth dichotomy — Judging vs. Perceiving — to Jung's original framework. Modern Development The MBTI was first published for general use in 1962 by Educational Testing Service. Since then, it has become one of the most widely used personality assessments in the world, administered to over 2 million people annually. It has been used in corporate team building, career counseling, relationship therapy, academic research, and personal development.
