MBTI Alternatives: The Best Myers-Briggs Alternatives in 2026

If the part of the MBTI you liked was the type itself, a short code that summarizes you and gives you a vocabulary for other people, there are three well-known tests built the same way.

16Personalities

Its codes look like MBTI types (INTJ, ENFP) with a fifth letter added, which is why many people assume it is the Myers-Briggs. Its own theory page is clear that it is a different model: it does not use Jungian concepts, and it describes its five scales as a reworking of the Big Five. The test is free.

Truity TypeFinder

Truity says TypeFinder is based on Myers and Briggs' theory but is not the MBTI assessment. It runs 130 questions and reports four dimensions of type plus 23 facets, so you see more texture inside your four letters. The brief report is free and the full report is paid.

The Enneagram

A different type system entirely: nine types, each with a neighboring wing that colors it. People who enjoy the MBTI often find the Enneagram more useful for motivation and stress. Our Enneagram alternatives guide and Opinion DNA vs the Enneagram cover its tradeoffs.

All three keep the strength of a type (it is memorable) and its cost (two people with the same code can differ a lot). If that tradeoff is fine for you, any of them will feel familiar.

The other family of MBTI alternatives drops types altogether. A trait test gives you a position on each scale, so a mild introvert and a strong introvert get different results instead of the same letter.

The standard here is the Big Five, the model most academic personality research uses. It also happens to overlap with the MBTI more than people expect. In a well-known 1989 paper, Robert McCrae and Paul Costa compared the two and found that four MBTI scales lined up with four Big Five traits: Extraversion-Introversion with extraversion, Sensing-Intuition with openness, Thinking-Feeling with agreeableness, and Judging-Perceiving with conscientiousness. The fifth trait, neuroticism, had no MBTI counterpart. That gap matters for the -A and -T question below.

So a Big Five test is, roughly, the MBTI measured as continuous scores, plus the emotional dimension the MBTI leaves out. Free versions based on public item pools are easy to find, and paid versions add interpretation. If you want the five traits with a written report, see our Big Five test page.

If your type reads INFJ-T or ENTP-A, the suffix did not come from the Myers-Briggs. The official MBTI reports four letters. The -A or -T is the fifth scale of 16Personalities, which it calls Identity. 16Personalities explains that its codes borrow the Myers-Briggs letter format and add one extra letter for this fifth scale.

According to 16Personalities:

• •Assertive (-A) people are self-assured, even-tempered, and resistant to stress. Their confidence comes from within.
• •Turbulent (-T) people are self-conscious and sensitive to stress, more responsive to outside influence, and prone to self-doubt. They also tend to be perfectionistic, success-driven, and eager to improve.

The site presents Identity as a scale that underpins the other four, and it describes an upside at each end: calm for the Assertive, and for the Turbulent, self-doubt that works as a motivator.

If that description sounds like a familiar trait, it should. Stress sensitivity, self-consciousness, and emotional reactivity are the core of neuroticism, the Big Five trait that the MBTI has no scale for. 16Personalities doesn't use that label, and its scale is its own, so treat the comparison as a resemblance. Still, it explains why the A or T letter often feels more revealing than the four letters before it: it reaches for the one major trait the original four leave out.

One caution. Because A and T is a single either-or split, it hides how you handle stress once it arrives. Opinion DNA scores neuroticism on a 0 to 100 scale and separately measures emotional reappraisal and suppression tendency, so you can see whether you feel things strongly, and also what you do about it.

Before switching tests, it is worth knowing that the publisher already sells a more granular MBTI. The Myers-Briggs Company describes Step II as a slightly longer version of the questionnaire that starts from your Step I type and splits each of the four preference pairs into five facets, 20 in total. Extraversion-Introversion, for example, breaks into facets such as Initiating-Receiving and Gregarious-Intimate.

The practical gain is nuance inside your type. In the publisher's sample reports, each facet result is marked in-preference, midzone, or out-of-preference, so an extravert who is reserved in one specific way can see exactly where. Step II is aimed at practitioners: the publisher notes that certified MBTI practitioners are already certified to use it.

Step II still describes you within the 16-type framework. If you want facet-level detail without the types, or want your values measured too, our guide to MBTI Step II alternatives compares the options.

Most lists of MBTI alternatives rank tests by accuracy, which is hard to judge from the outside. Four plainer questions sort them faster.

• •Do you want a type or a score? Types are easier to share. Scores show how far you lean.
• •What should it measure? Personality only, or also what you value and how you reason?
• •What do you get free, and what does the full version cost?
• •Who explains the results? A practitioner, a written report, or a label and a few paragraphs?

The table puts the main options side by side, using what each publisher states on its own site.

There are good reasons to stay with the MBTI. If your team already shares its vocabulary, switching tests means relearning a language that works. The official version also includes a step most alternatives skip: you confirm your best-fit type, either through MBTIonline's self-guided process or in a session with a certified practitioner, which catches results that don't feel right.

Its publisher is also direct about the limits. It says the MBTI measures preferences, can't measure or predict job performance, and can't tell a company who to hire. If you need a tool for team conversations, the MBTI and several alternatives can do that job. If you need to understand how a group's values and working styles fit together, see personality tools for teams and leadership or Opinion DNA for teams.

The tests above are mainly about personality: how you tend to act and feel. They don't score your moral intuitions or how you handle evidence and uncertainty, and those are often the questions people were trying to answer when they first took a Myers-Briggs test.

Opinion DNA measures 48 dimensions in three layers. Twelve are personality, including the Big Five and the Dark Triad. Twenty-four are values, from moral foundations such as fairness to personal values such as achievement. Twelve are meta-thinking, such as need for cognition and intolerance for uncertainty. Every dimension is a 0 to 100 score benchmarked against the population, and an AI-generated report reads them together across personality, values, career, and relationships.

It is 179 questions, about 10 to 15 minutes, $47 once, with a 30-day money-back guarantee. If you want the head-to-head first, read Opinion DNA vs MBTI. If you are ready, start the full assessment.
