Jung vs MBTI
MBTI grew out of Carl Jung — then quietly dropped his most important idea. Here’s the lineage, the difference, and why a Jungian approach goes deeper.
Almost everyone has taken MBTI. Almost no one realises it’s a simplified branch of Carl Jung — with the roots cut off.
MBTI’s Jungian roots
The Myers-Briggs Type Indicator was built in the mid-20th century on Jung’s Psychological Types. The four-letter code borrows directly from him: introversion and extraversion, thinking and feeling, sensing and intuition.
Jung’s psychological types
Jung’s original model described how attention flows — inward (introvert) or outward (extravert) — and four functions through which we take in and judge the world. He meant these as living tendencies in tension, not fixed boxes.
What MBTI kept — and dropped
MBTI kept the functions and turned them into sixteen tidy types. What it dropped is the part Jung cared about most: the shadow. It describes your conscious preferences and stops.
Why the Jungian approach goes deeper
A label tells you who you are on a good day. Jung was after the whole person — the bright side and the disowned one, and the tension between them. That tension is where change actually happens.
