16Personalities vs. Our Free 16 Types Test: What's the Difference
Both tests sort you into one of 16 four-letter codes, and both draw on the same general idea of psychological type. The difference is which questionnaire you're actually answering.
Same Concept, Different Instrument
16Personalities is a separate, independently run site with its own proprietary questionnaire. Our 16 Types test is a different, original 32-item questionnaire we wrote ourselves.
Neither one is the licensed MBTI instrument, and neither is a copy of the other. They're separate implementations of the same public-domain concept: four dichotomies (Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, Judging/Perceiving) combined into a 4-letter code.
Why the Same Person Can Get Different Codes
Every dichotomy is really a spectrum, and most people land somewhere near the middle on at least one of the four. A slightly different item wording, or a slightly different scoring cutoff, can push a near-middle score to the opposite letter.
That's not a bug in either test. It's what happens whenever two independent questionnaires measure the same fuzzy spectrum with different items.
What We Do Differently
Our version sticks to the four classic dichotomies, no extra proprietary traits layered on top. We publish our full methodology, including exactly how we score each dichotomy, so you can see how your result was calculated instead of taking a black box on faith.
If you want a trait-based second opinion instead of another 4-letter code, the Big Five test scores five independent dimensions with no fixed categories at all.
Which One Should You Take?
If you already have a 16Personalities result and want a quick second opinion from an independent questionnaire, our free 16 Types test takes about 8 minutes, no account or email required. Treat any difference between the two as a sign you're near the middle on that dichotomy, not as one test being "wrong."
FAQ
Is your 16 Types test a copy of 16Personalities?
No. It's our own original 32-item questionnaire, informed by the general public concept of Jungian typology, not a copy of 16Personalities or any other commercial instrument.
Why did I get a different code on each site?
Different questionnaires word their items differently and weigh them differently, so it's common to land close to the middle on one or more dichotomies and get pushed to opposite letters on two separate tests.
Which result should I trust more?
Neither is more official than the other. Both are independent instruments built around the same general typology concept, not licensed or validated against each other.
