IQ Scale By AgeScores & Scales

IQ Scale By Age

the IQ scale reveals that IQ levels fluctuate with age, suggesting that the mind is inherently unstable. The plethora of variables influencing cognitive capacities and the large range of IQs make it feasible for there to be differences in IQ between age groups.

Chart comparing machine and human performance across four task types, showing machines ahead on graduate science questions and coding, level on novel puzzle solving, and behind on tasks never seen beforeUnderstanding IQ

Is AI Smarter Than Humans?

Ask whether AI is smarter than humans and the honest answer depends entirely on the task. Frontier systems now beat expert humans on graduate-level science questions and lose to ordinary people on puzzles built to be unfamiliar. Here is what the 2026 benchmarks actually measure, and why one score never settles it.

What Is ChatGPT's IQ Score?

Search for ChatGPT's IQ score and you will find 155, 136, 116 and under 100, all reported seriously, sometimes for the same model. They are not contradictions to be resolved. They are different tests, scored different ways, and the spread between them is the most informative thing about the whole exercise.

Chart of what the cognitive debt essay-writing study measured, showing lower brain engagement and weaker recall in the AI-assisted group, alongside the outcomes the study did not measure including IQMind & Everyday Life

Does Using AI Make You Dumber?

The claim that AI is making us stupider has real research behind it and is still routinely overstated. No study has measured a drop in intelligence. What has been measured is lower mental engagement during a delegated task and weaker memory for work you did not do yourself, which is a narrower finding and a more useful one.

Chart comparing four published definitions of artificial general intelligence from OpenAI, Google, Microsoft and the ARC Prize Foundation, showing how little they overlap on what would countUnderstanding IQ

What Is AGI?

Artificial general intelligence means a system that can learn and apply knowledge across the full range of tasks a person can, rather than excelling at a narrow set. The trouble is that the major labs each publish a different definition, none of them converts into a test, and so claims that AGI has arrived cannot be checked either way.

Bar chart comparing chess training study results, showing a moderate effect on general cognitive ability in studies with no active control group, shrinking to near zero in the better-designed studies that used oneMind & Everyday Life

Does Chess Raise Your IQ?

Chess is one of the oldest test cases for a big question: does practicing a demanding mental skill make you generally smarter, or just better at that skill? The honest summary from decades of research: real for chess itself, modest for a couple of related skills, and close to zero for general IQ.

Horizontal bar chart of video game training effects by skill, showing a moderate improvement in spatial ability, a small improvement in executive function, and almost no measurable change in general intelligence test scoresMind & Everyday Life

Do Video Games Raise Your IQ?

Action video games produce real, replicated gains in spatial ability and attention, some of the best near-transfer evidence in this batch. Push the test further away, toward the general reasoning an IQ test measures, and the effect all but disappears once the research is pooled properly.

Does Reading Raise Your IQ?

Reading volume and vocabulary growth are genuinely linked, and the relationship compounds over years rather than staying fixed. But it is mostly the verbal, crystallized side of ability that moves, not the abstract reasoning an IQ test also measures, and cause and effect run both ways.

Bar chart of aerobic exercise effects on four executive function skills, showing real improvements in inhibitory control, working memory and cognitive flexibility, and no significant change in planningMind & Everyday Life

Does Exercise Raise Your IQ?

Aerobic exercise has some of the best-replicated cognitive evidence of any lifestyle factor, but not for a full IQ score. What reliably improves is executive function: working memory, inhibitory control, cognitive flexibility. One related skill, planning, barely moves at all.

Bell curve of IQ scores with everything below 120 shaded, showing that about 91 percent of people score below that mark and about 9 percent score at or above itScores & Scales

Is a 120 IQ High?

A score of 120 sits comfortably above average, and roughly nine people in ten score below it. But "high" is a comparison, not a property, and the honest answer depends on which scale produced the number, how much error is wrapped around it, and what you were hoping the score would tell you.

Two confidence intervals drawn on an IQ scale, one for a measured 97 and one for a measured 100, overlapping across almost their whole width to show that the two scores have not been told apartScores & Scales

Is 97 IQ Dumb?

A score of 97 is average. It sits three points below the population mean, which is well inside the margin of error of any test that produced it, so 97 and 100 are the same result in every way that can be measured. The interesting question is not what 97 says about you, but how little any single number can say.

Is 130 IQ a Genius Score?

A score of 130 is the conventional threshold for gifted identification and for high-IQ society membership, and it is reached by about one person in 44. It is not, however, a "genius" score, because no published test defines such a band. The word is a popular import, and the difference is worth understanding.

Bell curve of IQ scores with the region below 85 shaded and the separate threshold at 70 marked further to the left, showing about 16 percent at or below 85 against about 2 percent at or below 70Scores & Scales

What an IQ of 85 Means

A score of 85 sits exactly one standard deviation below the population mean, at roughly the 16th percentile. It is the bottom edge of what test manuals call low average, it is well clear of any clinical threshold, and on its own it says considerably less about a person than the number appears to.

Chart showing the supralinear relationship between childhood blood lead concentration and IQ score, with the steepest loss occurring across the lowest range of exposure rather than the highestResearch & Evidence

Lead, Pollution and IQ

Most things people believe raise or lower intelligence turn out to be small, contested or confounded. Childhood lead exposure is the exception: one of the best-established environmental effects on cognitive test scores anywhere in the literature, with a dose-response curve most people find counterintuitive.

Nutrition and IQ

The evidence on diet and intelligence looks contradictory until you separate two questions that get asked as one. Fixing a real deficiency produces some of the largest effects in the field. Adding more of the same nutrient to an already adequate diet produces close to nothing.

Stereotype Threat and Test Scores

Few findings in psychology have been cited as widely, or held up as poorly, as stereotype threat. The original experiments were elegant and the idea is intuitive. Two decades of replication attempts have left a much smaller and more uncertain effect than the textbook version suggests.

Diagram showing a confidence interval straddling the gifted cutoff of 130, illustrating how two children with different obtained scores can have overlapping true-score rangesScores & Scales

Gifted Cutoff Scores

Most gifted programmes draw their line at an IQ of 130. The number is a statistical convention rather than a boundary in nature, and three well-documented features of how the score is produced and used mean a strict cutoff reliably excludes children who belong on the other side of it.

Why Smart People Make Bad Decisions

Everyone knows someone brilliant who keeps making terrible calls. That is not a paradox; it is a measurement gap. Intelligence tests and rationality tests load on different things, and several of the best-studied thinking errors turn out to be almost completely independent of how high you score.

Chart showing the three natural-experiment designs used to estimate the effect of schooling on IQ (policy change, school-age cutoff and control for earlier intelligence), each yielding an estimated gain of roughly one to five IQ points per additional year of educationResearch & Evidence

Does School Raise IQ?

Education is the environmental factor with the strongest evidence for actually raising IQ scores, and the effect is bigger than most people expect. Three independent study designs, pooled across more than 600,000 participants, point the same way. Here is the size of it, and the caveat that gets dropped.

Processing Speed and IQ

Fast thinkers are assumed to be smart thinkers, and there is a real finding underneath the stereotype: people who score higher on IQ tests do respond faster on tasks with no reasoning content at all. But the link is weaker than the folklore, and on a professional battery the speed index is the least g-loaded.

How to Read an IQ Test Report

An IQ report puts numbers on at least three different scales and almost never explains which of them matters. Here is what FSIQ, the index scores, the subtest scaled scores, the percentile rank and that bracketed range each mean, and when the headline number should not be read at all.

Cultural Bias in IQ Tests

Ask whether IQ tests are culturally biased and you get two confident, opposite answers. Both are partly right, because the word means something far narrower to a psychometrician than it does in ordinary use. Here is what the item-level evidence shows, and where culture really does get into a score.

Brain Myths About Intelligence

You are not left-brained or right-brained, you do not use ten per cent of your brain, and matching a lesson to your learning style does not help you learn. Six claims about intelligence that almost everyone repeats, what the studies that tested them found, and the smaller true fact hiding inside each one.

Chart showing that a correlation of 0.5 between IQ and school achievement accounts for about 25 per cent of the variation, with the remaining 75 per cent attributed to prior knowledge, conscientiousness, motivation, teaching quality and circumstanceResearch & Evidence

Does IQ Predict School Success?

IQ predicts school achievement better than any other single measure psychologists have found, and still leaves roughly three-quarters of the variation unexplained. Both halves of that sentence get ignored by somebody. Here are the actual correlations, what they mean for one child, and what accounts for the rest.

Verbal vs Non-Verbal IQ Scores

Two people can hold the same IQ number and have completely different profiles, and a split between the verbal and non-verbal indexes is far commoner than most test-takers expect. Here is what base-rate tables and compounding measurement error say about how large a gap has to be before it means anything.

ADHD, Autism and Dyslexia in IQ Testing

Test Anxiety and IQ Scores

Almost everyone who has had a disappointing result has wondered whether nerves cost them fifteen or twenty points. The evidence says no.

Chart of creative achievement against IQ, contrasting the threshold claim that the line goes flat above 120 with re-analyses showing it keeps rising more gentlyResearch & Evidence

IQ and Creativity

The threshold hypothesis says IQ and creativity move together up to about 120 and barely at all above it. It is a real claim with a real number, and modern re-analyses have weakened it. Here is what the segmented-regression work found, why the two kinds of task differ, and why measurement noise matters.
