Platform · Cognition
Cognition is where AurorIQ began: instruments that measure reasoning ability itself. Not trivia, not speed-tapping games — adaptive assessments built on item response theory, reported as real percentiles with honest confidence intervals.
Twenty-five questions chosen live from your ability estimate, spanning five reasoning domains. You get a composite estimate, a percentile, a 95% confidence interval, and a cognitive archetype drawn from the shape of your profile. Free, no email, ~15 minutes.

The classic digit-span task, forward and backward — your working-memory span against approximate adult norms, in about five minutes.
Test your span → Available nowSimple visual reaction time — how fast you respond to a single cue. Five scored trials, median result, honest device-latency caveats, in about two minutes.
Test your speed → Available nowCognitive throughput, not just reaction time — thirty timed same/different comparisons scored as correct judgments per minute, so both speed and errors count.
Compare fast → Available nowA mental-rotation task — same shape rotated, or a mirror image? Twelve items scored on accuracy and speed, with exact ground truth.
Rotate some shapes → Available nowAnalogies, synonyms, and antonyms across three difficulty tiers — a difficulty-weighted measure of crystallized verbal ability, in about five minutes.
Reason with words → Available nowNumber series, syllogisms, deduction, and odd-one-out across three tiers — a culture-fair, difficulty-weighted measure of fluid reasoning, in about five minutes.
Follow the logic → Available nowNumber series, word problems, ratios, and data across three tiers — the quantitative half of reasoning, difficulty-weighted, with an honestly approximate percentile.
Test your numbers → Available nowThe Alternate Uses Task — two minutes to list as many uses for an object as you can. Honest divergent-thinking fluency, with originality openly not faked.
Unlock some ideas →What gets measured
Your composite score is built from distinct kinds of thinking. The balance between them — not the single number — is what defines your cognitive archetype.
Spotting the rule behind a sequence and predicting what comes next — the closest thing to raw fluid intelligence, and the least dependent on anything you were taught. Test your logical reasoning → · The science →
Relationships between quantities: proportions, progressions, and structure in numbers. This is reasoning with numbers, not arithmetic recall — a calculator won't help.
Analogies, meaning, and what follows from what. Verbal reasoning leans on crystallized knowledge more than the other domains, which is exactly why it's measured separately. Test your verbal reasoning →
Holding a shape in mind and transforming it — folding, rotating, recombining. Strong spatial profiles cluster in engineering, design, and the trades. Test your rotation → · The science →
How much you can hold and manipulate at once — the mental workbench every other domain borrows. It's the domain most sensitive to sleep and stress. Test your span → · The science →
After the test
A score without context is flattery. These are the two pages that turn your number into understanding.
One practical note before you begin: cognitive performance is state-dependent. Sleep debt, acute stress, and even time of day measurably move working-memory and processing scores, so a result from a rough night understates you. Test rested, test once, and treat the confidence interval — not the single number — as your actual result.
Every range from 70 to 145+, the population share at each level, and what the labels do and don't imply.

Each domain deserves its own dedicated instrument. These are being built to the same standard as the flagship — adaptive where it matters, honest everywhere.
Questions
Instruments that measure reasoning ability: the flagship adaptive IQ test, plus memory-span, reaction-time, mental-rotation, verbal-reasoning, logical-reasoning, and creativity tests. Each reports honest, percentile-based estimates — and where a score can't be measured honestly, we say so.
Because intelligence isn't one skill. Pattern, numeric, verbal, spatial, and memory reasoning draw on different cognitive machinery, and the balance between them — not just the composite score — is what defines your cognitive archetype.
Completely. Uneven profiles are the norm, not the exception. A strong spatial score with weaker verbal reasoning, or the reverse, simply describes the shape of your mind — it's the reason two people with identical composite scores can be entirely different thinkers.
Fifteen minutes from now, you'll know your archetype.
