Who Are the Smartest NBA Players? What the Combine Test Shows
No NBA player's IQ is public, so no one can be named the smartest. What exists is a basketball-specific test, the AIQ, given to 356 prospects at the NBA Combine from 2014 to 2019: players who reached the NBA scored higher on 3 of its 4 factors, with small effects.
What you need to know
- We found no published, verifiable IQ score for any NBA player, so we name none of the smartest NBA players and give no IQ for a living player.
- The basketball-specific cognitive test is the Athletic Intelligence Quotient (AIQ): 10 subtests on a tablet, 35 to 38 minutes, four factors (visual-spatial processing, reaction time, decision-making and learning efficiency). 356 prospects took it at the NBA Combine between 2014 and 2019 (Hogan et al., Frontiers in Psychology, 2023).
- Players who reached the NBA scored significantly higher than players who stayed below it on 3 of 4 factors and on the full-scale score. The authors call the effect sizes "somewhat small", and the paper's conflict-of-interest statement lists one author as employed by Athletic Intelligence Measures, LLC.
- The Wonderlic, 50 questions in 12 minutes, was the NFL combine's test until it was dropped from 2022, according to reports. It measures vocabulary, reading and maths; the AIQ is built to lean less on language and schooling.
The smartest NBA players cannot be named, because no NBA player's IQ is public. What exists is a basketball-specific test, the Athletic Intelligence Quotient (AIQ), given to 356 prospects at the NBA Combine from 2014 to 2019. In a 2023 study, players who reached the NBA scored higher than players who did not on 3 of the test's 4 factors, but the authors call the effects small.
Below: what the AIQ is and what the 2023 study found. Then how it differs from the Wonderlic used in the NFL. We also say why we give no IQ numbers for the smartest players in the NBA, and what a combine test can and cannot tell you.
Who are the smartest NBA players?
Who is the smartest NBA player? Nobody can be named, because the data that would settle it does not exist in public. There is no smartest player in the NBA on record. IQ scores are private test results. We found no published IQ score for any current NBA player from a test publisher, a study or the league. IQ lists on the web that name players cite none.
We therefore give no IQ numbers for living players, and we ask you to distrust any site that does. What can be checked is a player's performance on a cognitive test used in the draft, and that is where research exists. Our athlete IQ profiles follow the same rule: only verifiable academic records.
What test does the NBA Combine use?
The NBA Combine has used the AIQ, a tablet test of cognitive skills designed for sport. Hogan, Taylor, Boone and Bowman report that 356 NBA prospects took the AIQ at the NBA Combine between 2014 and 2019. It was part of the standard draft evaluation, and the players gave written consent. We could not confirm from a league source whether it is still given in 2026.
- Format: 10 subtests, presented in a fixed order on a 10.1-inch Android tablet, with audio and visual instructions and practice items
- Time: 35 to 38 minutes in total, about 3.5 to 3.8 minutes a subtest by our arithmetic
- Factors: visual-spatial processing, reaction time, decision-making and learning efficiency, plus a Full Scale AIQ score
- Design: answers are made by tapping the screen, and the authors say the tasks were built to minimise the effect of language, culture, formal education and technology skills
What did the 2023 study of 356 NBA prospects find?
Players who reached the NBA had higher AIQ scores, but the gaps were small. Of the 356 prospects, 227 (64%) went on to have some NBA experience and 129 (36%) had professional experience below the NBA level only. Independent-samples t-tests showed the NBA group scored significantly higher on 3 of the 4 factors and on the Full Scale AIQ Score. Drafted NBA players also had significantly faster reaction times than either non-NBA or undrafted NBA players.
The second test was whether the score predicted performance. After controlling for draft position, the AIQ predicted some statistically significant but modest relationships with NBA statistics such as Player Efficiency Rating and effective field goal percentage. The authors write that the effect sizes were "somewhat small" and consistent with the restricted range among professional athletes.
Players who reached the NBA scored higher on 3 of 4 factors, and the authors call the effects "somewhat small".
Does a high AIQ score make a better NBA player?
Not by itself. A small effect after controlling for draft position means the score adds a little information to what scouts already know from film and physical tests. The study does not show that it can pick out who will succeed. The study is also a single data set, with players who were already selected for the combine, which narrows the spread of scores and weakens any correlation.
A conflict-of-interest note matters too. The paper's statement lists one author as employed by Athletic Intelligence Measures, LLC, and says another author's employer is not affiliated with the AIQ. That does not make the findings wrong, but it is a reason to wait for studies by independent teams.
How is the NBA test different from the Wonderlic used in the NFL?
The Wonderlic is a 50-question, 12-minute test of vocabulary, reading and maths, and the AIQ is a 35-to-38-minute tablet test of spatial, reaction-time and decision tasks. Wonderlic gives about 14.4 seconds a question, our arithmetic on its own timing. Our Wonderlic score guide reports that the NFL stopped using it at the Scouting Combine from 2022. The sources are a league memo reported in January 2022 and a New York Times report of 2 March 2022.
The AIQ authors argue that the Wonderlic measures "learned skills" and has shown a lack of predictive validity for sport performance, citing earlier studies. That is the authors' argument, and the paper's conflict statement is a reason to read it with care. For how the Wonderlic maps to IQ, see our piece on Wonderlic score to IQ, and try the format yourself with the Wonderlic practice test.
Do NBA players have a high IQ?
We cannot say, because no sample of NBA IQ scores has been published, which is why any list of the smartest NBA players is a guess. A sport-specific test is not an IQ test. The AIQ reports its own full-scale score, and nothing in the paper converts it to the IQ scale (average 100, standard deviation 15). Our guide to average IQ by occupation shows how rare it is to have solid IQ data for any single job.
What should employers and fans take from this?
- Treat a cognitive score as one input: the AIQ study found small effects after draft position was controlled
- Ask who ran the study: authors tied to the test company are a reason for caution
- Do not read a sport test as an IQ: no conversion exists in the paper
- Check the date: the Wonderlic left the NFL Combine in 2022, and we could not confirm the NBA's current use of the AIQ
- Prefer measures with published norms when you hire: a test with norm tables lets you read a score against a known group
The same cautions apply outside sport. Our note on rules for hiring tests in the EU covers what employers must document, and our cognitive assessment for hiring teams page explains what we offer. To see where your own reasoning falls on the population scale, take the IQ test and read the result with the IQ percentile calculator.

Who is the smartest NBA player?
No one can be named. No NBA player's IQ is public, and we found no verifiable IQ score for any current player. The only research uses the AIQ, a basketball-specific cognitive test, and it reports no IQ numbers.
What test does the NBA use to measure intelligence?
The NBA Combine used the Athletic Intelligence Quotient (AIQ) for 356 prospects between 2014 and 2019: 10 tablet subtests in 35 to 38 minutes. We could not confirm from a league source that it is still used in 2026.
Do NBA players with higher AIQ scores perform better?
Slightly. A 2023 study found NBA players scored higher than non-NBA players on 3 of 4 factors, and the AIQ predicted some modest relationships with statistics after controlling for draft position. The authors call the effect sizes somewhat small.
Is the Wonderlic used in the NBA?
No source we found says so. The Wonderlic (50 questions, 12 minutes) was the NFL combine's test until reports said it was dropped from 2022, and the NBA research uses a different test, the AIQ.
