20 questions covering number sequences, verbal analogies, spatial logic, and pattern reasoning. Take your time - there's no timer. Get an estimated IQ range at the end.
This test samples four domains assessed in real IQ batteries: verbal analogies (Gc), numerical sequences (Gq), spatial pattern reasoning (Gf), and logic (Gf). Each domain contributes to the broad construct of general intelligence (g). General intelligence (g) is the most researched human benchmark in all of psychology.
For more targeted tests, try Pattern Recognition (pure Gf) and Cognitive Reflection (analytical thinking).
General intelligence is the most researched human benchmark in all of psychology โ this free test gives you a meaningful signal without the cost of formal testing.
Intelligence Quotient (IQ) scores summarize performance across multiple cognitive domains into a single standardized number, where 100 represents the population average and each 15 points represents one standard deviation. The term was coined by William Stern in 1912, though the first practical IQ test was developed by Alfred Binet in 1904 to identify French schoolchildren needing educational support. Modern IQ batteries like WAIS-IV measure several distinct components: verbal comprehension, perceptual reasoning, working memory, and processing speed.
Our Mini IQ Test samples four reasoning domains across 20 questions: number sequences (numerical reasoning), verbal analogies (language/crystallized intelligence), logical deduction (fluid reasoning), and spatial patterns. The resulting estimated range is a rough indication - not a certified IQ score - but the patterns of strengths and weaknesses across question types reveal genuine cognitive profile information. Important: only a licensed psychologist administering a standardized, normed battery can provide a valid clinical IQ score.
Online IQ scores fluctuate more than clinical scores because of testing conditions - time pressure, distractions, and unfamiliarity with question formats all lower performance regardless of underlying ability. Sleep and stress have the largest short-term impact, while practice on similar question types ("test-retest" effect) can raise scores by 5-10 points without a true increase in reasoning ability. Fluid reasoning (pattern-based, novel problem solving) is considered more stable than crystallized intelligence (vocabulary, learned facts), which grows with education and life experience.
No. This is a free online estimate based on 20 reasoning questions. Only a licensed psychologist administering a standardized, normed battery like the WAIS-IV can provide a valid clinical IQ score.
100 is the population average by definition. Scores of 115-129 are considered "Superior" (about 14% of people), and 130+ is "Very Superior" (about 2% of people).
Practice on similar question formats can raise scores by 5-10 points through familiarity, but this reflects test-taking skill rather than a genuine increase in underlying fluid reasoning ability.
No, this test focuses on verbal, numerical, spatial, and logical reasoning - it does not assess emotional intelligence, creativity, or social skills, which require different assessment tools.
Yes, you can share your estimated range, but keep in mind it's a fun benchmark rather than a certified score, so it's best framed as an informal result rather than a clinical measurement.
Fluid intelligence is the ability to reason and solve novel problems, while crystallized intelligence relies on accumulated knowledge and vocabulary - this test samples primarily fluid reasoning.
IQ scores are standardized so the population average is set at 100, with each 15-point deviation representing one standard deviation, making it easy to compare an individual's score to the general population.
No. A single online test result can be affected by fatigue, unfamiliarity with the question format, or time pressure, and should never be treated as a diagnostic or clinical outcome.
Formal assessments are longer, professionally administered, and cover more cognitive domains under controlled conditions, making them far more reliable than any free online screening tool.
The test has 20 questions spanning number sequences, verbal analogies, logical deduction, and spatial patterns, and takes most people 8-12 minutes to complete.
