How TraitMix calculates your type
Most sites ask separate questions for each letter. TraitMix works the other way round: you take a 20-item Big Five test built from public-domain research items, and each letter is read off one trait. Extraversion gives E or I, Openness gives N or S, Agreeableness gives F or T and Conscientiousness gives J or P. That keeps the code tied to the best-studied model of personality.
The fifth trait, emotional stability, has no letter. It still matters a lot, especially for stress and relationships, so it appears in your full report and in the guide to emotional stability.
A shortcut, not a box
A type is a handy label for a mix of scores. Two people with the same four letters can still differ a lot if one is at 55 and the other at 95 on a scale. Read the type pages as a starting point for conversation, then look at your actual scores. Our guide to what each letter means explains the scales in detail.
Using types with a partner, family or team
Types are most useful when you compare them. Ask everyone to take the 16 types test, then open the compare view to see where you match and where you pull in different directions. The compatibility guide explains how the match score is calculated.
Frequently asked questions
Is this the MBTI?
No. MBTI® is a trademark of The Myers-Briggs Company and TraitMix is not affiliated with it. We use the familiar four-letter format, but our letters are calculated from Big Five scores.
Which type is the rarest?
It depends on the sample and the method, so treat rarity claims with care. On a Big Five based system, codes that combine scores far from average on several scales are naturally less common.
Can my type change?
Letters near the middle of a scale can flip between tests, and traits drift slowly across adulthood. A letter with a strong score is usually stable.
