- Extroversion vs. Introversion (E, I)
- Sensing vs. Intuition (S, N)
- Thinking vs. Feeling (T, F)
- Judging vs. Perceiving (J, P)
The codes for these sixteen types are formed by listing one choice per opposite (E,I), (S,N), (T,F), and (J,P), written ESTJ, for example. Interestingly, four special subsets xNTx, xNFx, xSxJ, xSxP, (usually written NT, NF, SJ, SP), are aligned to the four personality temperaments by David Keirsey.
Sensing vs. Intuition and Thinking vs. Feeling are quite similar to the fourfold of Jung’s Psychological Types: Sensation, Intuition, Thinking, and Feeling. Also in Jung’s theory Intuition and Sensation are considered Perceiving, and Thinking and Feeling and considered Judging. However, there are significant differences in the two theories.
