Is this a real IQ test?

It is a real cognitive skills test that reports your result on the familiar 85–145 scale used by traditional IQ scoring. It is not a clinical IQ assessment — those are administered one-to-one by a licensed psychologist using instruments such as the WAIS-IV.

Do I have to pay to see my score?

No. Your cognitive index score and percentile are shown free, immediately after the final question. Detailed reports are an optional one-time purchase, and there is no subscription.

How long does the IQ test take?

Sixteen questions across four reasoning domains. Most people finish in under five minutes.

How is the score calculated?

Each of the 16 items falls into one of four categories: numeric reasoning, verbal reasoning, logic, and pattern recognition. Your raw score across all four is converted into a cognitive index on a 85-145 scale, modeled on a standard mean-100 / SD-15 distribution, purely as a familiar frame of reference.

What is the difference between the report tiers?

The Score Report ($1.99) unlocks your full 4-category percentile breakdown. The Deep Report ($3.99) adds a written analysis of your reasoning pattern and a thematic historical figure match based on your strongest category. The Complete Report ($6.99) includes everything plus a printable certificate.

Overall Summary
Your puzzle responses indicate a constructive reasoning pattern combining systematic deduction with an ability to hold multiple relational concepts simultaneously. You tend to resolve ambiguity by narrowing to structure rather than intuition.

Strongest Reasoning Signal
Your Logic scores were most pronounced — you consistently identified which premises were sufficient and which required additional constraints. This reflects deliberate, rule-governed thinking rather than trial-and-error pattern matching.

Thematic Historical Match
Your Logic result echoes the kind of thinking associated with Aristotle — not a numeric comparison, but a shared tendency to formalise relationships between statements before drawing conclusions.
