16 Personality Types Test

What it measures

This test maps your self-reported preferences across four Jungian dichotomies — Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving — and assigns you one of sixteen four-letter personality codes (e.g. INTJ, ENFP). It is a freely available educational typology inspired by the Myers-Briggs Type Indicator® (MBTI®) tradition.

How it works

You rate sixteen statements on a five-point agreement scale. Your responses are tallied separately for each of the eight poles (E, I, S, N, T, F, J, P). For each of the four axis pairs, whichever pole scores higher contributes its letter. The four letters concatenate into your type code, which maps to one of sixteen classic type descriptions. The whole assessment takes about three to four minutes.

Tips for an accurate result

• 1Use it as a starting point, not a verdict — Type frameworks are best treated as prompts for self-reflection rather than fixed labels. Notice what resonates and what does not.
• 2Read the full type description, not just the headline — Each type includes growth areas alongside strengths. The growth sections are often the most useful.
• 3Discuss it with people who know you well — Others' observations of your behaviour often reveal blind spots that self-report misses, particularly on the Extraversion/Introversion and Judging/Perceiving axes.
• 4Retake it in six months — Life circumstances, therapy, and deliberate practice can genuinely shift where you fall on each axis — type is not destiny.
• 5Explore the Big Five if you want scientific depth — The Big Five (OCEAN) model is the dominant framework in personality research and predicts real-world outcomes more reliably than typologies.
