The Myers-Briggs Type Indicator (MBTI) is the most-recognised personality model in the world. Its publisher reports that as many as two million assessments are administered each year. It is used in Fortune 500 hiring, leadership development programmes and university orientation. It is also the model most heavily criticised by personality researchers, who consider it scientifically weak on multiple criteria (Pittenger, 2005).

That contradiction creates a real question for anyone choosing a personality framework: if MBTI is so popular but so questioned, what is the better alternative? This article compares MBTI with the sixteen Norse archetypes Elementals uses, both at the conceptual level and at the level of practical use. The aim is not to dismiss MBTI — it has real strengths — but to be honest about where it falls short and what works better.

What MBTI gets right

To be fair to the model: MBTI did three things well that explain its enduring popularity.

Accessible language. "INTJ", "ENFP" and the other sixteen codes give people a shorthand for talking about themselves. The terminology is memorable, shareable and conversational in a way that "67th percentile on openness" is not.

A narrative for self-recognition. MBTI type descriptions are richly written. People recognise themselves in them and find them useful for reflection. That recognition — even if it is partly Barnum-effect — has real motivational value for self-development.

Pragmatic team conversations. In team settings, "we have three ENTPs and one ISTJ" gives leaders a quick language for thinking about composition. The conversations that follow can be valuable, even when the underlying typology is flawed.

These strengths are real. They explain why MBTI does not die despite repeated academic criticism. People want the things it offers.

Where MBTI scientifically falls short

But the academic criticism is also real, and worth understanding before placing weight on MBTI results in important decisions.

Test-retest reliability is weak. Pittenger (2005) summarised studies showing that 39–76% of people receive a different type when they retake the test five weeks later. For a model claiming to measure a stable type, that is a critical problem. If you are sometimes INTJ and sometimes INTP, the type is not measuring something stable about you.

The dichotomous categories do not match the data. MBTI divides each dimension into two categories (Introvert vs Extravert, Thinking vs Feeling, etc.). But when researchers measure these dimensions on a continuous scale, the distribution is normal — most people score in the middle, not at the extremes. Forcing them into a category creates artificial differences between people who actually differ very little (McCrae & Costa, 1989).

Predictive validity is low. MBTI types correlate weakly with job performance, leadership effectiveness, relationship satisfaction and other outcomes that personality tests claim to predict. The Big Five, measured continuously, consistently outperforms MBTI on every external validity criterion (Furnham, 1996).

The model is not derived from data. MBTI was built on Jung's typology, which Jung himself developed from clinical observation rather than systematic research. The Big Five, by contrast, was derived empirically — by factor-analysing thousands of personality descriptors and seeing which dimensions emerged. The Big Five "found itself"; MBTI was designed first and tested second.

None of this means MBTI has no value. It does mean that for any decision with real consequences — hiring, team composition, therapy planning — the empirical evidence favours Big Five-based tools.

How Norse archetypes compare

The sixteen Norse archetypes in Elementals are designed to combine MBTI's strengths (narrative, memorable types, team language) with the Big Five's empirical foundation. Here is how the comparison works in practice.

Same number of types, different basis. Both systems produce sixteen archetypes. MBTI's sixteen come from four dichotomous dimensions (2^4 = 16). Norse archetypes come from a clustering of Big Five score combinations — they emerge from the data rather than from a logical grid. The result is sixteen patterns that match observed personality clusters rather than logical possibilities.

Continuous scores, narrative output. A Norse archetype assessment measures your scores on the five Big Five dimensions continuously. The archetype name (Odin, Freyja, Tyr, etc.) is a label for the pattern your scores create, not a category that erases the underlying variation. Two people who both receive "Odin" can have meaningfully different scores within the Odin pattern, and the report reflects that.

Test-retest reliability is high. Because the Big Five is empirically stable over time, an archetype assessment based on Big Five scores inherits that stability. Meta-analytic work on Big Five measures reports dependability coefficients clustering around 0.80 over intervals of up to a couple of months (Gnambs, 2014). Someone classified as Odin in March is very likely to be Odin again in October, with possibly some movement within the Odin pattern.

The narrative is myth-based, not invented. MBTI type descriptions were written by Myers and Briggs as part of the typology. Norse archetype descriptions draw on existing mythological narratives — Odin's wisdom-seeking, Tyr's principled sacrifice, Loki's adaptive trickery — which carry cultural depth that artificial type labels lack.

Predictive validity inherits the Big Five. Because Norse archetypes are derived from Big Five scores, they inherit the Big Five's validity for predicting work outcomes, relationship satisfaction, leadership effectiveness and life satisfaction. The narrative wrapper does not change what is measured; it only changes how the measurement is communicated.

When each model is useful

To be fair to both systems, here is when each one has its place.

Use MBTI when:

You need conversational shorthand among people already familiar with the system
The decision being supported has low consequences (team-building day, casual self-reflection)
The audience strongly prefers MBTI and resistance to a new model would dominate the conversation

Use Norse archetypes or another Big Five-based system when:

The decision has real consequences (hiring, coaching, therapy, team composition)
You need a result you can compare across time (someone's progress, before-and-after of an intervention)
You want a measure that holds up to scrutiny from researchers, psychologists or sceptical colleagues
You are building a self-knowledge practice that will inform decisions over years

Norse archetypes, in our view, hit a sweet spot: the narrative depth that makes MBTI sticky, with the empirical grounding that makes Big Five trustworthy. That is by design — see our article on which Norse archetype are you for the underlying mapping logic.

What about other alternatives

A few other models deserve brief mention.

DISC. Behavioural model used widely in sales and management. Measures dominance, influence, steadiness and conscientiousness. Practical but narrower than Big Five, and underdeveloped on emotional dimensions. See DISC versus Big Five.

Enneagram. Nine-type model with significant narrative depth but weak empirical foundation. Useful for personal reflection but inappropriate for evidence-based decisions. See Enneagram versus Big Five.

Strengths-based tools (CliftonStrengths, VIA). Focus on strengths rather than personality. Useful as a complement to Big Five but not a replacement — they answer different questions.

Direct Big Five tests (NEO-PI, IPIP, BFI). The most evidence-based options, but report scores in percentiles rather than narratives, which makes them harder to apply for non-specialists. The Norse archetype layer in Elementals is essentially a translation layer on top of this kind of test.

The bottom line

If you took MBTI a decade ago and built your self-image on the result, you have not wasted time — much of what you learned about yourself was probably accurate, because MBTI does pick up signal even if it muddles it. But if you are choosing now, between MBTI and a Big Five-based system like Norse archetypes, the empirical evidence is one-sided. Choose the system with better measurement properties, the same number of useful types, and equivalent narrative depth.

Want to compare your Norse archetype to your MBTI type if you have one? Take the free Big Five test — five minutes, and you receive your archetype with scores you can compare to anything else you have taken. The narrative is built on the same Jungian heritage as MBTI but on a much firmer measurement base.
