Explore five reasoning domains and read your result alongside its limits.
A 3-parameter item-response engine chooses each question from your live ability estimate. The current version reorders the same 25 questions using your earlier responses. Its item parameters have not been empirically calibrated.
Your result includes a descriptive archetype — drawn from the shape of your profile. Architect, Sage, Cipher, Visionary, Polymath.
A position on an assumed normal curve, not a measured ranking against other test takers.
We tell you what this measures and what it doesn't. An estimate for reflection — never a clinical claim, never inflated to flatter.
Send a friend the same adaptive test and see your minds head-to-head — archetype against archetype, score against score.
What gets measured
Your composite score is built from distinct kinds of thinking — and their balance is what defines your archetype.
The experience
A short warm-up tunes the test to your level, so it starts where you actually are.
Twenty-five questions move through five domains, each one chosen live from your responses.
Your score ascends, your archetype assembles, and your place on the curve lights up.
Under the hood
No black boxes. This is exactly how your result is computed — and where it lives.
A three-parameter item-response model re-estimates your ability after every answer and picks the next question where it carries maximum information.
Percentiles are adjusted along a fluid-reasoning curve, so a 19-year-old and a 60-year-old are each compared to their true peers.
Every estimate ships with its confidence interval. A number without its error bars is flattery — we report both.
There is no server scoring your answers. The engine runs in your browser and results are stored on your device — nowhere else.
Identity
Same score, different shape, different archetype. That's the part worth comparing.
Personica maps your personality across scientifically grounded dimensions \u2014 the traits that shape how you use your intelligence. Discover the complete picture.

AurorIQ produces a percentile-based estimate using an adaptive item-response engine. It's a tool for reflection and curiosity — not a clinical assessment. Only a proctored test administered by a licensed psychologist using a validated instrument such as the WAIS-IV qualifies for clinical, educational, or legal purposes.
It describes the shape of your profile — which reasoning domains are strongest relative to the others. Two people with the same overall score can be different archetypes.
No. AurorIQ scores can't be used for Mensa or any clinical, educational, or legal purpose. Those require a supervised assessment with a validated instrument.
AurorIQ is an intelligence platform — a growing set of free, science-grounded instruments that measure how you think. The flagship is an adaptive IQ test; personality testing lives on our sister instrument Personica, alongside the learning, career, and productivity tools available here.
No account, no email, and no sale of your answers. The assessment is scored in your browser and your results are stored on your own device.
Fifteen minutes from now, you'll know your archetype.
