A free, original sitting of Jung’s eight function-attitudes. Informal — not official MBTI and not a clinical type.

Carl Jung’s 1921 Psychological Types described two attitudes (extraversion and introversion) and four functions (sensation, intuition, thinking, feeling). Combined, teachers later wrote eight “function-attitudes”: Se, Si, Ne, Ni, Te, Ti, Fe, Fi. Myers and Briggs added a fourth letter (J/P) and built 16 types. This quiz stays closer to the eight processes. It is original and unofficial.
Read Jung’s eight functions explained after your result. For four-letter codes take the 16 types test. For traits take the Big Five.
