History of Personality Typology: From Jung to Modern 16 Types
What Is the History of Personality Typology?
Ancient Foundations: The Four Temperaments
1. Attitude Types: Extraversion and Introversion
Jung was the first to systematically describe these fundamental orientations:
- Extraversion: Energy directed toward the external world
- Introversion: Energy directed toward the inner world
2. The Four Psychological Functions
Jung identified four primary ways humans process information and make decisions:
- Thinking: Logical analysis and reasoning
- Feeling: Value-based judgments and emotional considerations
- Sensation: Perception through the five senses
- Intuition: Perception of possibilities and patterns
3. Function Hierarchy
Jung proposed that each person has:
- One dominant function (most developed)
- One auxiliary function (supporting role)
- One tertiary function (less developed)
- One inferior function (least developed, often unconscious)
Jung's Eight Types
Mother-daughter team Katherine Cook Briggs (1875-1968) and Isabel Briggs Myers (1897-1980) transformed Jung's complex theories into a practical assessment tool.
Katherine Briggs began studying personality differences in the 1920s, initially developing her own typology before discovering Jung's work. She became fascinated by Jung's theories and spent years studying and expanding upon them.
Isabel Briggs Myers inherited her mother's passion and possessed the practical skills to create a usable assessment. During World War II, she was motivated to help women entering the workforce find suitable jobs.
The Fourth Dimension: Judging vs. Perceiving
The Briggs–Myers team made a crucial addition to Jung's framework by adding a fourth dimension:
- Judging (J): Preference for closure, structure, and decided matters
- Perceiving (P): Preference for flexibility, spontaneity, and open options
This addition was based on Jung's observation that people differ in how they approach the external world – whether they prefer their judging function (Thinking or Feeling) or their perceiving function (Sensing or Intuition) to be extraverted.
Birth of the 16 Types
By adding the J/P dimension, Myers and Briggs created 16 distinct personality types, each represented by a four-letter code:
Analysts (NT)
- INTJ, INTP, ENTJ, ENTP
Diplomats (NF)
- INFJ, INFP, ENFJ, ENFP
Sentinels (SJ)
- ISTJ, ISFJ, ESTJ, ESFJ
Explorers (SP)
- ISTP, ISFP, ESTP, ESFP
David Keirsey: Temperament Theory
The Four Temperaments Revisited
1. Guardians (SJ) - Traditional
- Value security, stability, and established procedures
- Approximately 40-45% of the population
2. Artisans (SP) - Tactical
- Seek freedom, spontaneity, and immediate impact
- Approximately 25-30% of the population
3. Idealists (NF) - Diplomatic
- Focus on personal growth, authenticity, and helping others
- Approximately 15-20% of the population
4. Rationals (NT) - Strategic
- Prize competence, knowledge, and theoretical understanding
- Approximately 10-15% of the population
Keirsey's Contributions
Digital Age Adaptations
Ongoing Research
Modern researchers continue to:
- Improve assessment reliability
- Study cross-cultural validity
- Explore neurological correlates
- Develop applications in organizational psychology
Impact on Modern Society
Personality typing has spread worldwide, with adaptations for different cultures and languages, though questions remain about universal applicability.
The Future of Personality Typology
Conclusion
While debates about scientific validity continue, the practical value of personality typology in helping people understand themselves and others remains undeniable. The framework provides a common language for discussing differences, a tool for self-reflection, and a bridge to better relationships.
As we look to the future, personality typology will likely continue evolving, incorporating new scientific insights while maintaining its core mission: helping people understand and appreciate the beautiful diversity of human psychology.
Understanding this rich history enhances our appreciation for personality typing not as a simple categorization system, but as a sophisticated framework built on decades of careful observation, theoretical development, and practical application.

Example 3: Keirsey Making Typing Accessible
Each contributor built upon previous work, creating increasingly useful tools for understanding human nature. Jung's revolutionary insights provided the theoretical foundation. Briggs and Myers transformed complex theories into practical assessments. Keirsey made typing accessible to general audiences. Modern researchers continue improving assessment reliability, studying cross-cultural validity, and developing organizational applications.
