What is the Flynn effect?
When you score today’s sample on yesterday’s norms, averages often sit above 100 — sometimes by several points per decade on some tests, especially visuospatial and matrix-like items. Publishers renorm so 100 stays the population mean.
Does that mean people got much smarter?
Not in a simple sense. Gains were larger on some tasks than others. Schooling, nutrition, smaller families, extraversion toward abstract test formats, and reduced disease burden are among hypothesized drivers. g as a latent factor may have moved less than the raw scores.
Why do some tests show bigger gains?
Culturally loaded knowledge tests and highly abstract pattern tests did not always move in lockstep. Flynn himself argued we became better at certain scientific and taxonomic habits of mind, not that every cognitive system scaled equally.
What is the reverse Flynn effect?
Some countries later showed plateau or decline in scores. Causes may include education changes, test composition, immigration mix, or a ceiling on earlier environmental lifts. See our reverse-Flynn explainer; do not invent a single global story.
Should I compare my online score to a 1970s chart?
No. Percentiles only make sense against the norms of the test you took. Our practice games are not normed at all. A high matrices-lite count is a game score, not a Flynn-adjusted IQ.
What can I play that feels “Flynn-ish”?
Pattern-matrices-lite uses original simple shapes (not Raven). Mental-math and visual-search tap speeded, test-like attention. They remain games.

What Is a Good IQ Score?
An IQ of 100 is exactly average; 110-119 is above average, 120 and up puts you in the top 10% (a genuinely 'good' score), and 130+ is considered gifted. IQ is built on a normal distribution with a mean of 100 and a standard deviation of 15, so most people cluster near the middle.
What Is a Good IQ Score? →IQ Percentile Chart: What Percentile Is My IQ?
Your IQ percentile tells you the share of people you scored higher than: an IQ of 100 is the 50th percentile, 115 is about the 84th, 120 is roughly the top 10%, and 130 is roughly the top 2%. The table below maps every major IQ band to its classification, percentile, and share of the population.
IQ Percentile Chart: What Percentile Is My IQ? →Are Online IQ Tests Accurate?
A well-designed online IQ test gives a reliable estimate of your reasoning ability, but it is not a clinical diagnosis — only a proctored test like the WAIS or Stanford-Binet provides that. This test is built on Raven's Progressive Matrices and CHC theory, scored on the standard scale (mean 100, SD 15), with an internal reliability (Cronbach's alpha) of about 0.85-0.92.
Are Online IQ Tests Accurate? →Can You Increase Your IQ?
You can meaningfully sharpen reasoning skills, working memory, and test performance through training and education, but raising your underlying general intelligence (g) substantially and permanently is not well supported — core g is largely heritable. The honest answer is that some gains are real and some popular claims are overstated.
Can You Increase Your IQ? →Genius IQ Level: What Number Counts as Genius?
A 'genius' IQ traditionally starts at 140, while 130 and above is labeled 'very superior' on modern tests. Scores that high are extremely rare, and the famous IQ numbers you see for historical figures are almost always estimates, not measured results.
