Your type, without rigid boxes

Q: Is this the same as the MBTI?

No. We use the generic four-axis format (E/I, S/N, T/F, J/P), but with our own model and archetypes, without Jungian cognitive functions and, most importantly, on a continuous scale anchored in the Five-Factor Model (Big Five). We have no affiliation with the MBTI, a third-party trademark.

Q: Why a continuous scale?

Because most people land in the middle of the axes, not at the extremes. Showing a percentage (e.g., 60% Introversion) is truer and more stable than forcing a fixed side, which is one of the main scientific criticisms of type tests.

Four axes (energy, perception, decisions and structure) on a continuous scale, anchored in the Big Five. Discover your four letters and your archetype.

This is a free 16 personality types test: 48 statements, about 8 minutes, no sign-up. It organizes personality into four axes (E/I, S/N, T/F, J/P), as in the 16-types tradition, but on a continuous scale and empirically anchored in the Five-Factor Model (Big Five): energy maps to Extraversion; perception to Openness; decisions to Agreeableness; structure to Conscientiousness. No cognitive functions and no forced dichotomies. The result is a self-knowledge estimate, not a diagnosis.

Your four axes

Each axis is a continuum, not a box: the dot shows which side you lean to and how much. Near the middle = you use both sides depending on the situation.

You across life areas

How your type tends to show up in daily life — what to lean into and what to balance. A developmental estimate, never a verdict.

How it's calculated — and the science

The four-axis format (energy, perception, decisions and structure) is a popular convention for describing personality. Instead of using cognitive functions (which lack empirical support) or forcing you onto a fixed side, we anchor each axis in one of the Five Factors (Big Five), the most validated model in psychology, and show the result on a continuous scale.

The correspondences are documented in the literature (McCrae & Costa, 1989; Furnham, 1996): Energy (E/I) ↔ Extraversion; Perception (S/N) ↔ Openness; Decisions (T/F) ↔ Agreeableness; Structure (J/P) ↔ Conscientiousness. Each axis has 12 statements (24 per direction, counterbalanced). We sum and convert to a percentage for each pole; the four letters form your code, and together they define the archetype.

Reliability · limitsThe biggest scientific criticism of “type” tests is dichotomization: forcing someone in the middle to one side reduces the stability of the result (you can “switch type” at a borderline). That's why we use a continuous scale and anchor it in the Big Five. Even so, it's self-report and a simplification: treat it as a starting point, not a definitive label. Reference year: 2026.

Independent · no trademarksThis test is not the MBTI® and is not affiliated with it. We use only the generic four-letter convention, with our own model, items and archetypes. The names and types are original.

Important · read firstA tool for self-knowledge and personal development; it does not replace a formal psychological assessment by a licensed professional. The result is an estimate, not a diagnosis.

Author's note

This is the test people look for most, and the one I was most careful to build without copying anyone: no trademarked four-letter codes, no third-party archetype names. These are classic personality dimensions with names and territories of my own. If you came for the “type,” stay for the nuance.

Frequently asked questions

Is this the same as the MBTI?

No. We use the generic four-axis format, but with our own model and archetypes, without Jungian cognitive functions and, most importantly, on a continuous scale anchored in the Big Five. We have no affiliation with the MBTI, a third-party trademark.

Why a continuous scale?

Because most people land in the middle of the axes. Showing “60% Introversion” is truer and more stable than forcing a fixed side, which is precisely the scientific criticism of type tests.

Is it free?

Yes, 100% free, no sign-up and no email. The result appears instantly and is saved only in your browser.

How long does it take?

About 7 to 10 minutes. There are 48 statements on a 1-to-5 scale.

Can I land in the middle of an axis?

You can, and it's common. When you're near 50%, we show it. That means you move between both sides depending on context.

Your type says how you tend to act. What you're actually aiming at is a different question: the Schwartz values test maps the ten basic human values behind your choices, and it pairs unusually well with this one. If traits are what you're after, start from the Big Five that anchors these four axes.
