Chess Rating ELO and IQ Score Correlation
Many people are curious if there is a correlation between one’s chess rating and IQ score. I did some information research, compiled facts and data and decided that it should be a good time to write an article about IQ score and ELO rating correlation.
If there is a correlation between IQ and ELO it would be also interesting to know how strong it is. Is it true that only people with high IQs can be strong chess players? Do all strong chess players have high IQs? We will try to answer those and other questions throughout this article.
First of all we need to figure out what is IQ. It is an abbreviation for intelligence quotient, which is a numerical score derived from one or more standardized tests. Most average humans have an IQ score of 100, while 95% of population has IQ between 70 and 130. But what do these tests actually measure, or at least attempt to measure? That something is called intelligence. Strangely enough there isn’t any good formal definition for this word. Many understand what it means but only few can define it.
According to Wikipedia, intelligence includes the abilities, but not limited to:
1. abstract thinking
2. understanding
3. self-awareness
4. communication
5. reasoning
6. learning
7. having emotional knowledge
8. retaining
9. planning
10. problem solving
Again, this is not a full list, but just a few classical intelligence model characteristics. Which of this 10 abilities are needed to be successful in the game of chess?
Abstract thinking is definitely something needed for playing chess, the chess pieces can be visualized in terms of their relative pawn value and arrows to represent ability to move.
Understanding is defined as knowing about the object and be able to deal with it. That’s also definitely needed in the game of chess. For example, all chess players know that a chess knight (an object) can move L-shaped and jump the pieces (behavior), the only way to stop threatened with a knight piece is to capture the knight (dealing with problem).
Self awareness is the ability to differentiate yourself and others: “I think, therefore I exist, as a thing that thinks.” It’s not directly correlated to the thinking process in chess, but it’s common to all humans and even some animals like apes and elephants. I’m not sure what the elephant’s IQ scores or ELO ratings could be, but they definitely possess some intelligence, according to this list.
Communication is technically not needed to be good at chess. However, it’s very hard or nearly impossible to become a good chess player without communicating with others who play chess. Since reading a chess book, acquiring knowledge from the chess database or studying an endgame on TheChessWorld.com is a form of visual communication, it is absolutely essential for success at chess. Let me take it back, communication ability is essential to be a strong chess player.
Reasoning is the capacity of humans to make sense of things, establish and verify facts. That’s is definitely one of the very important abilities for chess players since they use it for many different things while over the chess board. Chess position analyses is one of the examples when reasoning plays a crucial role at chess.
Learning is acquiring new or modifying existing knowledge or skill. In chess it’s actually both. Learning to play openings is acquiring a new knowledge. Sharpening tactics by the means of solving chess problems is modifying existing skill. Ability to learn is absolutely essential for a chess player.
Having emotional knowledge also plays some role in chess. For example, if a person hates losing at chess he we use that negative stimulus and prior emotional knowledge to avoid it in future. He can either learn and play better chess or stop playing chess to avoid loses.
Retaining is absolutely important for chess. Good memory can give a chess player a huge advantage against another player. Ability to memorize chess games, position, classical endgames and openings is essential for playing high level chess.
Planning is a key of any chess game. Chess is all about planning and strategy. In order to outplay your opponent you need to come up with a plan which is suitable for specific position and also execute it well. Wikipedia defines strategy as plan aimed for gaining (or being prepared to gain) a position of advantage over adversaries or best exploiting emerging possibilities. That’s perfectly applicable to chess, since we want to take advantage of all the available resources on the chess board to actually win the game.
Problem solving is something that a chess player does literally during each move while playing chess. He has to make many decisions throughout the game and figure out ways to defend and attack, develop pieces and manage time. Tactics is also 100% problem solving.
As we can see from the list above 9 out of 10 intelligence characteristics are also very important for the game chess. From that we can make a conclusion that in order to be a strong chess player, one needs to possess a higher than average level of intelligence. But does that mean that a good chess player must have a high IQ score? That all depends on how accurately and reliably can IQ test measure one’s intellectual abilities. Many scientists debate whether or not an IQ test is actually an accurate enough measure of intelligence since it estimates IQ based on many false assumptions. Some scientists dispute the idea of IQ entirely since they believe that it is impossible to evaluate one’s intelligence based solely on standardized tests.
As of my opinion, I believe that IQ test is not an accurate measure of intelligence, it’s only a measure of how well a person can take specific test (a skill which can be learned). Therefore, making a statement that a person with high IQ will necessarily be a strong chess player or a person with high ELO will have high IQ score is not correct.
Here is the IQ Chart from Levitt’s Genius in Chess:
IQ 185 High natural neuro-kinesthetic control; high curiosity drive; anti trivia; in a hurry
IQ 180 New creation
IQ 175 Knows intelligent (and right!)
IQ 165 Formalization; beginnings of self confidence; less hiding
IQ 160 Interest in logic; paranoia; minor creation; recognizes good work; art; music
IQ 150 Trivial formalization
IQ 145 Below this level and often above is everywhere found a slavery to conditioning
Levitt states that the population of IQ distribution is as follows (100 being an average IQ):
16% above 115
2.3% above 130
0.13% above 145
0.003% above 160
Levitt comes up with a equation which relates ELO and IQ score:
ELO ~ (10 x IQ) + 1000
The “~” symbol means “given many years of effort will tend to be equal approximately”.
If we plug in 100 IQ (average IQ score) into equation we will get 2000 ELO, meaning that an average person should be rated 2000. However, some chess players (actually most chess players) play their whole life and never reach even 1700, making 2000 mark fall into top 4-5% of all chess players on planet. So, maybe this ‘1000’ term in the equation needs to be decreased somewhat.
Here is an (estimated) list of IQ scores of famous chess players:
Garry Kasparov Chess player Russia 190
Bobby Fischer Chess player USA 187
Donald Byrne Chess Player Ireland 170
Judith Polgar Chess player Hungary 170
Robert Byrne Chess Player Ireland 170
International team of psychologists have attempted to measure IQ score of Garry Kasparov and after many tedious tests has concluded Kasparov’s IQ to be 135, making him fall into ‘moderately gifted’ category. According to the Levitt’s equation Kasparov’s ELO should be 2350 and not 2850 as it is in reality.
Conclusions:
1. There is a direct correlation between the intelligence level and chess ability
2. IQ tests are not an accurate measure of intelligence level and therefore cannot be accurately compared to ELO
3. Levitt’s formula, correlating IQ to ELO, is not accurate and the ‘1000’ coefficient should be somewhat decreased.

I don’t understand how you came to your list of conclusions at all. You give a list of characteristics that are commonly linked to intelligence, and say that it seems they should influence chess rating. Then you say that IQ tests are hotly debated, and somehow that section of the article is concluded as ‘There is a direct correlation between the intelligence level and chess ability’, and ‘IQ tests are not an accurate measure of intelligence level and therefore cannot be accurately compared to ELO’. I mean dude. Everything about this article just says ‘inconclusive’. Just be honest and make the article into something that provides the background and an overview of the relevant issues instead.
I am listed with an IQ 160 in the World Genius Directory but my FIDE rating is only 1852. Levitt´s formula relatizing IQ and ELO is ridiculous.
Hikaru Nakamura has only 102 points from the IQ test of norwegian Mensa but he has rating 2900 in blitzgame.
That’s a funny example of how IQ tests are generally not good indicators of intelligence – Nakamura not only plays incredibly intelligent – he also speaks and behaves very intelligently.
I think it more goes to show how much hard work and dedication from a young age can help you be successful in whatever you focus on. I think that’s how Nakamura looks at it himself as well.
There is no validity to your statistical approach. Indeed, back into your solution. The faulty start is the ’10’ at the beginning – that is made up and flawed. You spent a lot of time wasting time – yours and ours.
This is preposterously stupid. This whole article is inaccurate. The general ‘ assumption ‘ of intelligence factors are factual ingredients that make up intelligence. Intelligence is, essentially, patterns. And more intelligence people understand more patterns in numerical formats ( English, Mathematics, Theater, etc ) The gist of a quotient is it’s ratio compared to what we revolve and be a revolver to, everybody. Intelligence tests comparatively ( meaning objectively ) judge off the whole body of earthly inhabitants. It is true that one might do horrible on a iq test, but that just means one wasn’t judged correctly if he is ‘ actually ‘ intelligent. Your claim of Chess not correlating to intelligence is completely dubious just based off your kasporov claim — which , essentially , is that either the adolescent IQ test is dubious ( which is probably the most correct and logical explanation ) or kasporov just didn’t perform well on it. The best at the ‘ thinking mans ‘ game is of sub-par intelligence? Yeah right!
Chess is not existence.
Yury, thanks for me letting me know that as long as a person has the desire/motivation/resources/ability, they can make it. That’s needed motivation if I am going to be a Chess Grand Master and World Champion. I just want to be World Champion for even one year.
[quote name=”D.Master20ify”]I completely agree with Chesslet. If you study Chess when you are six it will have more impact on your brain development than if you study it at age 25. because at age 6 your brain is still in the developmental stage.
Studies do show that stimulating the brain causes the development of more neurons or something of such in the brain. If you don’t stimulate the brain for example: a baby that was kept in the baby pen until it was 10, that baby would be unstimulated and stupid.[/quote]
That is true. However there are also examples when people start playing chess later in life and achieve notable results, such as GM titles by the time they are 40. If you have desire/motivation/resources/ability there is nothing that can stop you 🙂

That number 16 person bananabender obviously has no respect for Chess. But I know that Chess is a game that requires intelligence even if it is not at the Rocket Science level.
Yes, memorization of previous positions plays a great role in Chess; but everyone Chess player knows that calculating concrete variations is a necessity of Chess. Case in point: as you get older your Chess ability decreases, because of your lack of ability to calculate as when you were young. Anataly Karpov is now loosing to persons now that couldn’t dream of beating him in his youth.
Concrete Calculations is something that I am actually working on right now. I noticed that my online ratings was budging the 1800 section, even though I have 4 years experience and I play Chess almost 24/7, seen many tactical positions, solve losts of tactics puzzle, know lots of positional ideas and strategy. My brain is full of Chess games! Yet I am not reaching 2000 and having a problem beating those play
I’m a fairly strong chess player [elo around 2000 which puts me in the 4th percentile of players but I only know the results of a spatial intelligence test I did during my studies in electronics [tied with another guy who I felt was far superior to me intellectually – we scored 135]
I have friends who play chess well & consider them all to be very intelligent, although there are people in the chess community who at best have a tenuous grip on reality…& such individuals may have crossed paths with #16 to help promote his ideas about chess players in general being nothing special.
Those who appear genuinely intelligent to #16 have spent enormous amounts of time honing whatever skill/abilty they might have.
I’m sure that my math IQ would be much higher if I spent time playing around with numbers so that hidden numerical relationships were second nature to me…
Same goes for any mental ability…assuming you are not disabled you can raise your IQ score by practice/study of related material.
People who score > 120 but show no ability at chess in spite of prolonged effort have a problem with something like creativity at the board under time pressure or perhaps don’t have the competitive drive or ‘will to win’.
If Kasparov is only 135 there’s either a flaw in the test or he has spent too little time on areas outside chess!
Chess players spend a great deal of time and effort trying to convince themselves and others how intelligent they are.
Unfortunately for chess players there are 120 years of high quality academic studies which show that the ability to play chess has little or no relationship to intelligence. Way back in 1893 Alfred Binet (who developed the first IQ tests) showed that most Grand Masters only have average intelligence. Since then numerous studies have shown that chess ability is mostly due to diligent practice.
Studies have also shown that chess ability does not transfer skills to any other domain such mathematics or non-chess memory tasks.
There is even some evidence to suggest that a very high IQ actually [b]reduces[/b] the chess laying ability of children (presumably they get bored).
Computer have zero intelligence yet they can effortlessly beat any human player.
Where is Tahl? 😛
A player with a very high rating will probably have a high IQ. A player with a low rating doesn’t always have a low IQ.
Phew, that’s a limitation of the formula 🙂
Samuel Hunt, the correlation of IQ vs. ELO shows that with a proper training a person of high IQ can achieve a higher ELO than a person with a lower IQ. In case of Einstein’s 1400 ELO: he did not have a proper training nor motivation for chess. If he did, he could’ve been a really strong player (GM level most likely).
Mike Burns, many sources show 190: here is one of them http://www.therichest.com/business/the-top-10-most-intelligent-people-in-the-world/
Many sights have Kasparov IQ at 182. This article is way off.
I once had a member of MENSA come to my home to see how intelligent I was. They called me and sought me out. He literally said that he didn’t think there was any test I could take to test my IQ. He was there as a representative to determine “If I could be tested or if I was so far out there that I was not able to be tested.” My rating is only 1700 at present. I scored a perfect score on the last standardized, peer-reviewed, published RSPM intelligence test. I made that score in less than 10 minutes for 60 questions. Citing a few cases, does not make a correlation, nor does it make it legitimate theory. Einstein and Oppenheimer was reported to only have a rating of approximately 1400.
LOL,what if someone has an elo of 1000 or USCF 600 or so?Haha
I strongly disagree with the conclusion in this article. There is more a relation of how hard you train for chess or at which age you start learning and your Elo, than between IQ and Elo. Everyone knows this for sure. If u start to learn chess at age of 25 your Elo will strongly increase but your IQ will not. Maybe statistically you will find a weak correlation for professional players but I would never ever call it a relation. If you are highly intelligent in the area of language it doesn’t nessecarily mean that your chess will be good. Comparing apples and oranges will not lead to compelling results.
PLease see my published article here: http://digitalcommons.wku.edu/ijes/vol5/iss3/8/
In it I describe the biological cascades that correlate to increased neurogenesis comparing chess, exercise, and nutrition. My dissertation research will compare chess and exercise, a combined group and a control group on both Intelligence and Neurogenesis.
I agree that IQ test score is not accurate enough to predict future chess performance. I also believe that true intelligence level has a direct correlation with maximum potential ELO (after years of training, effort and coaching). My point is that true intelligence level sets an upper limit on what your maximum ELO rating could become. Someone with a low intellignce level could never become a grandmaster – they simply do not have enough brain power to achieve it. But someone with a high intelligence level could become a grandmaster (after years of training, effort and coaching), however, they may never reach their full potential. In the case of Garry Kasparov, I believe he has maximized his potential, but others with a higher true intelligence level (after years of training, effort and coaching) could surpass him, like for example Magnus Carlsen. Levitt’s equation can only be considered valid for “potential” ELO, not “actual” ELO.
Dan, Levitt’s equation isn’t accurate at all. You cannot really get an IQ from it, since 1000 rated player would just get IQ = 0… which can’t be true.
In equation conditions it says that it’s valid after many years of effort. I think it should also be added that with proper coaching. Hope that clarifies things a bit 😉
@John Herron, the point I was trying to stress in the article is that IQ test score cannot be accurate enough to predict future chess performance. Standardized tests are simply not reliable enough for that purpose. The true intelligence level (not the IQ score) is something that has correlation with ELO, but again I believe that it can be increased with proper training.
With a chess score of 1700, this gives me an iq of 70!
It’s a miracle I can raise my finger, let alone actually type an email!
Me too stoopid2 continu.
I believe there is a direct correlation between IQ and “potential” ELO. Garry Kasparov may indeed have only a moderately gifted intelligence, but he has maximized his chess “potential” with dedication and a lot of hard work. He admits this in his book, “How Life Imitates Chess.” I believe everyone has the ability to become a chess player, but they are limited in how good they may become by their IQ. Similarly, everyone has the ability to become an athlete, but they are limited in how good they may become by their physiology. I also agree that IQ tests do not always determine intelligence levels accurately. It is a very tricky assessment that is not so easily quantified and reduced to a single number. There are many different kinds of intelligence, and many different ways to measure it.
Since Garry Kasparov’s chess genius is truly exceptional, but IQ score is just “moderately gifted” it means one of two things: either the IQ tests he have taken do not determine intelligence level accurately or the correlation between IQ and ELO is not as simple. I think the first statement is true though.
Garry Kasparov may be only moderately gifted in general intelligence, but he is definitely a genius in chess! Likewise for Bobby Fischer and many others. I believe there is a direct correlation between one’s IQ and one’s maximum chess “potential,” but this potential may or may not actually be achieved.
