16-Type Personality Test

It is a free personality test that sorts people into 16 types across four dimensions: Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving. You answer a series of questions and receive one of the 16 personality types.

This is a free, educational test intended for self-reflection. Many people find type-based results insightful, though researchers debate how well categorical types capture personality compared with trait-based models like the Big Five. Treat your result as a helpful starting point rather than a clinical diagnosis.

This personality test consists of 74 carefully selected questions and takes about 15 minutes. For the most accurate results, answer in a calm environment without distractions.

Your core preferences tend to stay relatively stable through life, but personal growth, life experience, and stress can change how you express your type. Many people get a slightly different result when retaking the test after several weeks, especially on dimensions where their preference is mild.

The 16 types are: ISTJ, ISFJ, INFJ, INTJ, ISTP, ISFP, INFP, INTP, ESTP, ESFP, ENFP, ENTP, ESTJ, ESFJ, ENFJ, and ENTJ. Each is a unique combination of the four preference dichotomies and describes patterns in how you energize, take in information, make decisions, and organize your life.
