Four letters, honestly scored.
Fifty-eight questions read your type across four dichotomies and an identity axis, with two facets under each letter and a cognitive function stack most type tests never show you. A coin-flip letter gets called a coin flip.

Sliders, not boxes. The percentage is the real result; the letter is shorthand.
The function stack, included
Your four letters imply a stack of cognitive functions: the mental move you lead with, the one that supports it, and the one that trips you at 2am. The biggest type sites skip this layer entirely. We derive it from your letters, weight it by how clear each preference actually was, and include the shadow functions for readers who want the deep end.
Trademark note: this test uses Jungian dichotomies and is not affiliated with The Myers-Briggs Company. We call it what it is: a 16-type test.
Most people argue with one letter.
