Most “free” IQ tests aren't.
You take a 40-minute test, type in your email, and then — surprise — a paywall asks for $19.99 to unlock the score you just earned. We built Noēsis as the opposite of that.
Typical IQ sites
- Hide your score behind a paywall
- Force an email or account
- Sneaky recurring subscriptions
- Inflate scores to upsell you
Noēsis

Five kinds of reasoning
A balanced test draws on more than one ability. Here's what each section taps into.
Abstract Reasoning
Raven's-style visual matrices — find the rule that completes the pattern.
Measures: Fluid intelligence & pattern induction
Number Series
Infer the hidden rule in a sequence and predict what comes next.
Measures: Quantitative reasoning
Verbal Reasoning
Analogies and relationships between words and concepts.
Measures: Verbal comprehension
Logical Deduction
Draw the conclusion that must follow from the premises.
Measures: Deductive logic
Spatial Reasoning
Rotate and transform shapes in your mind's eye.
Measures: Spatial visualisation

This is a Raven's-style abstract reasoning item — the kind psychologists consider the purest measure of fluid intelligence because it needs no language or learned knowledge.

Questions, answered
Is this IQ test really free?+
Yes — completely. You get your full estimated IQ score and a per-category breakdown the instant you finish. There is no sign-up, no email wall, and no payment at any point. Many 'free' IQ sites make you take a long test and then charge $20 to see your result; we never do that.
Do I need to create an account or give my email?+
No. You can take the test and see every part of your result without an account, an email address, or a credit card. The test is scored in your browser and your answers never leave your device.
How is the IQ score calculated?+
Each of the 30 questions has a difficulty weight. Your weighted performance is mapped onto the standard IQ scale, which has a mean of 100 and a standard deviation of 15 (a 'deviation IQ'). That means about 68% of people score between 85 and 115. We explain the full method on our methodology page.
How accurate is an online IQ test?+
An online screening test like this gives a reasonable estimate, but it is not a substitute for a clinically administered, individually-normed test (such as the WAIS) given by a psychologist. Treat your score as a fun, useful snapshot with a meaningful margin of error — not a diagnosis.
