The Myers-Briggs Type Indicator (MBTI) is a widely used personality assessment tool that categorizes individuals into one of 16 personality types. Developed by Katharine Cook Briggs and her daughter Isabel Briggs Myers, the MBTI is based on Carl Jung’s theory of psychological types, published in his 1921 book Psychological Types.
The MBTI identifies personality types based on four dichotomies, each representing a pair of opposing preferences:
Extraversion(E) vs. Introversion(I)
- Extraversion (E): Prefers to focus on the external world, gaining energy from social interactions and external activities.
- Introversion (I): Prefers to focus on the internal world, gaining energy from solitude and internal reflections.
Sensing(S) vs. Intuition(N)
- Sensing (S): Prefers to focus on the present and concrete information, valuing facts, details, and practical solutions.
- Intuition (N): Prefers to focus on future possibilities and abstract information, valuing insights, patterns, and innovation.
Thinking(T) vs. Feeling(F)
- Thinking (T): Prefers to make decisions based on logic, objectivity, and rational analysis.
- Feeling (F): Prefers to make decisions based on values, emotions, and the consideration of feelings.
- Judging (J): Prefers a structured and organized approach to life, seeking closure and making decisions quickly.
- Perceiving (P): Prefers a flexible and adaptable approach to life, keeping options open and exploring possibilities.

Combining these preferences, the MBTI generates 16 personality types, each represented by a four-letter code. Each type describes how a person perceives the world, makes decisions, and interacts with others.
