How to Study Personality Types
From MBTI to Sasang constitution and color psychology
There are so many personality tests that it is easy to lose track of how they differ. Look first at what a test is actually doing, then take the major typologies one at a time, and you can choose the one that suits you.
Stage 1 · Understand typologies
Begin with what personality tests can and cannot measure. Then take the most widely used one, MBTI, at both levels: the sixteen types and the cognitive functions beneath them.
- 1. Enjoying Personality Tests — From MBTI to Blood Type — Why personality tests like MBTI, blood type, the Sasang constitutions, and color psychology are so fun — and how to enjoy them wisely.
- 2. The 16 MBTI Types, Fully Explained — Four Axes and the Combinations of Personality — What the four indicators E/I, S/N, T/F, and J/P measure, and how to understand the 16 types by grouping them into four temperament clusters.
- 3. MBTI Cognitive Functions — The Workings of the Mind Behind the Four Letters — Why does the same four-letter type feel different from person to person? A step deeper into MBTI, into the eight cognitive functions and how their ordering shapes a personality.
Stage 2 · Add other perspectives
Compare different lenses — including the fact that blood-type personality has no scientific basis — alongside Sasang constitution and color psychology. Several perspectives make your self-understanding fuller.
- 4. Blood Type Personality — Temperament by A, B, O, and AB — The origins of the blood type personality theory beloved in East Asia, the signature temperaments of the four blood types, and the right attitude for enjoying it in fun.
- 5. Sasang Constitutions — Body and Personality Through Four Constitutions — The characteristics of the four constitutions Lee Je-ma's Sasang medicine defined — Taeyang, Taeeum, Soyang, and Soeum — and the basics of their health and food guidance.
- 6. Color Psychology — Seeing Yourself Through the Colors You Love — The principle of the emotions people feel from color, and the dispositions revealed by warm colors, calm colors, and achromatic colors, laid out from the perspective of color psychology.
