What is MBTI? A plain-language guide to the 16 types
MBTI (the Myers-Briggs Type Indicator) sorts how you prefer to take in information and make decisions into 16 types, each written as four letters — like INFP or ESTJ. It is built on Carl Jung’s idea of psychological preferences, and it describes leanings, not fixed limits. Diahu’s MBTI-style quiz reports a type as a starting point for reflection, not a label that defines you.
What do the four letters measure?
Each letter marks a preference on one axis: where you draw energy (Introversion / Extraversion), how you take in information (Sensing / Intuition), how you decide (Thinking / Feeling), and how you organize your world (Judging / Perceiving). Your type is the combination that feels most natural — not the only way you can act.
Is MBTI scientifically valid?
Psychologists generally see MBTI as a useful self-reflection language rather than a clinical instrument; trait models like the Big Five hold up better in research. That is exactly why Diahu frames a type as a conversation starter, and pairs it with the Big Five for a more measured read.
How should I use my type?
Treat it as a hypothesis about your tendencies, then check it against real situations at work and in relationships. The most useful move is noticing where the description fits and where it does not.
