Explore how Carl Jung's theory of Psychological Types laid the foundation for the MBTI. Learn the history of personality theory and analytical psychology.

The personality categories we often take for granted today didn't just fall out of a psychology textbook; they were born from a mother’s intense desire to understand why her daughter was different from her, and how to help people find their 'best version' of themselves.
How was mbti invented by Carl Jung

While Carl Jung did not directly create the Myers-Briggs Type Indicator, his 1921 work, Psychological Types, provided the essential theoretical framework. Jung introduced the concepts of introversion and extraversion, along with the four cognitive functions: thinking, feeling, sensation, and intuition. Katharine Cook Briggs and Isabel Briggs Myers later expanded upon these Jungian archetypes to develop the practical testing instrument known today as the MBTI.
Analytical Psychology is the broader school of thought founded by Carl Jung, focusing on the human psyche, the collective unconscious, and individuation. The MBTI is a specific application of Jung’s personality theory designed to make his complex ideas accessible for everyday use. While Jung focused on the fluid nature of the psyche, the MBTI history shows a shift toward categorizing individuals into sixteen distinct, stable personality types.
Carl Jung developed his theory of Psychological Types to explain the fundamental differences in how individuals perceive the world and make decisions. He observed that what appeared to be random variation in human behavior was actually quite orderly and consistent. By defining different personality types, Jung sought to provide a tool for better self-understanding and to improve communication between people with different psychological orientations.
