The 16 Personality Types Test: MBTI Explained and a Free Alternative
What does the 16 types test really measure?
Jung's typology, popularized by the MBTI indicator, describes personality along 4 dichotomies. Each axis places the respondent between two poles: you're never 100% on one side, but you have a dominant preference. The combination of the 4 preferences forms a 4-letter code (e.g., INFP, ESTJ) corresponding to one of the 16 types. The point isn't the label but understanding your natural preferences: how you recharge, process information, decide, and organize yourself.
In the article that follows, I explore personality types. If you recognise yourself in this theme, I designed a 16 personality types test that helps you take stock of your personality profile. It comes with a guide to extend your reflection beyond the results.

The MBTI® is a commercial, trademarked instrument. Many free tests (including this one, or 16personalities.com) measure the same Jungian dimensions without being the official MBTI. The result is comparable in spirit, but no free online test is the certified MBTI®. This makes no difference for personal-development use.

Research considers the 16-types typology a useful framework but one with moderate reliability: test-retest stability is imperfect (you can change type between two assessments) and the clear-cut categories simplify a continuous reality. For a more robust measure of personality, the Big Five model (OCEAN) is the scientific reference. The 16 types remain excellent as a support for dialogue, teamwork, and introspection.
