What is MBTI?
The Myers-Briggs Type Indicator (MBTI) is the original 16-type personality assessment. Katharine Briggs and her daughter Isabel Briggs Myers built it from Carl Jung's theory of psychological type, and its publisher, The Myers-Briggs Company, dates the first version to 1942. Individuals can take the official assessment online through MBTIonline; organizations use it through certified practitioners.
You answer the official questionnaire and get a four-letter type built from four preference pairs: Extraversion or Introversion, Sensing or Intuition, Thinking or Feeling, and Judging or Perceiving. On MBTIonline you then confirm your best-fit type through a self-guided process. Through a certified practitioner, that confirmation happens in a feedback session.
Types versus scores: the core design difference
The MBTI is a type instrument. Its publisher describes Step I as sorting you into one of 16 types, and the official process ends with you confirming the four letters that fit best. That design is the point: a type is easy to remember, easy to share with a team, and easy to build a workshop around.
Opinion DNA is a trait instrument. Every result is a 0 to 100 score benchmarked against population averages, so two people who would share an MBTI letter can still sit at visibly different places on, say, extraversion or openness. Nobody gets rounded to the nearest letter.
The second difference is scope. MBTI measures personality preferences. Opinion DNA's 179 questions cover 12 personality dimensions, including the Big Five (with neuroticism, which no MBTI letter targets) and the Dark Triad, plus 24 values such as care and self-direction, and 12 meta-thinking dimensions such as intellectual humility. It takes about 10 to 15 minutes and costs $47 once.
Weighing more than these two tests?
If you are deciding between the MBTI and a whole field of options, our guide to MBTI alternatives sorts them into tests like Myers-Briggs (for people who like types) and trait-based tests (for people who want scores), and explains where 16Personalities' -A and -T suffixes come from. If you already know you want to go past four letters, this overview of tests beyond Myers-Briggs walks through what a broader profile covers.

MBTI limitations
- −Sorts you into one of 16 types, so someone near the middle of a scale can land on a different letter on another day
- −Measures personality preferences only, not values, moral intuitions, or reasoning style
- −Its publisher says it doesn't measure performance and can't predict job performance
- −Organizations need certification or education eligibility to buy and administer it
- −Built on Jung's type theory, while most academic personality research uses trait models such as the Big Five
