About MBTI Theory
Discover the scientific foundations and historical development of the Myers-Briggs Type Indicator, one of the world's most widely used personality assessments.
Carl Jung's Psychological Types
"Every individual is an exception to the rule."— Carl Gustav Jung
The MBTI is based on Carl Jung's groundbreaking 1921 work "Psychological Types," where he identified fundamental differences in how people perceive the world and make decisions. Jung observed that what appears to be random variation in human behavior is actually quite orderly and consistent.
Jung identified key psychological preferences that influence how individuals:
- Focus their attention and energy
- Gather and process information
- Make decisions and reach conclusions
- Approach the external world
Jung's Original Concepts
Extraversion vs Introversion
How and where you direct your energy and attention - toward the outer world or your inner world.
Sensing vs Intuition
How you gather information - through direct experience or by looking for patterns and possibilities.
Thinking vs Feeling
How you make decisions - based on logical analysis or personal values and impact on people.
Myers-Briggs Development
Katharine Cook Briggs & Isabel Briggs Myers
In the 1940s, mother-daughter team Katharine Cook Briggs and Isabel Briggs Myers expanded upon Jung's work to create a practical assessment tool. They were motivated by the belief that understanding personality differences could help people better understand themselves and each other.

How the 16 Types Are Formed
The 16 personality types result from the combination of four independent preference dimensions. Each person has a natural preference for one side of each dimension, creating 2×2×2×2 = 16 unique combinations.
The Four Dimensions
Energy Direction
E vs IExtraversion (E): Energy directed outward, focus on external world
Introversion (I): Energy directed inward, focus on inner world
Information Gathering
S vs NSensing (S): Focus on concrete facts and details
Intuition (N): Focus on patterns, possibilities, and meanings
Decision Making
T vs FThinking (T): Decisions based on logic and objective analysis
Feeling (F): Decisions based on values and impact on people
Lifestyle Orientation
J vs PJudging (J): Preference for structure and closure
Perceiving (P): Preference for flexibility and openness
