Frequently asked questions

What do the four letters mean?

Each letter is a preference: E or I (extraversion or introversion), S or N (sensing or intuition), T or F (thinking or feeling) and J or P (judging or perceiving). The combinations form 16 types.

Where does this classification come from?

From Carl Jung's theory of psychological types, later developed by Katharine Briggs and Isabel Myers. This test is our own short questionnaire, inspired by those four preferences, and it is not the official instrument.

Is the result final?

No. The preferences work as a scale, and many people land near the middle on one or more letters. Psychologists consider this kind of test imprecise: use it for self-knowledge and conversation, not for important decisions.
