About the MBTI 16 Personality Types Test

What is MBTI and the 16 Personality Types?

MBTI (Myers-Briggs Type Indicator) is one of the world's most popular personality assessment tools, based on Swiss psychologist Carl Jung's theory of psychological types. By assessing four core dimensions—Extraversion/Introversion (E/I), Sensing/Intuition (S/N), Thinking/Feeling (T/F), and Judging/Perceiving (J/P)—personalities are classified into 16 distinct types such as INTJ, INFP, ENFP, and more. Sites like 16Personalities have made MBTI testing globally popular.

How the MBTI Test Works

This MBTI personality test contains 60 carefully crafted questions evenly distributed across four dimensions (15 per dimension). It uses a 5-point Likert scale scoring system with normalization algorithms to calculate your preference strength on each MBTI dimension, ultimately producing your four-letter personality code (e.g., INTJ, ENFP).
