Relationship between Chess rating and I.Q?

not sure if anyone's posted this before, but here's a 2016 meta-analysis on this topic: https://artscimedia.case.edu/wp-content/uploads/sites/141/2016/12/22143817/Burgoyne-Sala-Gobet-Macnamara-Campitelli-Hambrick-2016.pdf. There appears to be a real relationship between IQ and chess ability, but it appears to have a small-moderate effect size in general and a still smaller effect size among adult and higher rated (>2000) populations.

I agree with blueemu -- clever, well adjusted people tend to shy away from devoting their lives to games. (I'm a pro poker player btw)

I think I.Q only correlates by ease to learn and calculate

Si ven la curva de IQ, y la curva de rating de ajedrez en Chess.com o en cualquier otro lado, se daran cuanta que es identica. Ahora, influye o no ?

Depends on how much study of Chess has been done, surely.

Given an equal amount of dedication and stability of temperament, I suspect that the more Intelligent would tend to have a higher rating.

I find myself in the same camp as most people. I would bet the top players are all pretty intelligent in areas outside of chess, but the link is probably not terribly strong. A more interesting study would be someone's playing strength directly after learning the rules. I think chess is mostly learning and practice, though like anything there are exceptions.

Little to no relation.  So many other factors are involved, including quality of vision and understanding of certain patterns to look for in certain situations.  It's kind of like saying how well someone speaks English is a high reflection of IQ.  It's not a huge reflection of IQ though, it's a reflection more of experience with English and a good natural voice.

And now...  How capable were the greats outside of chess?  Bobby Fischer sure wasn't.  Kasaparov never made it far politically.  Carlsen isn't known for a thing of which I am aware outside of chess.

So then why is my rating 500 if I should be 1706 player

That formula gives me an IQ over 186. Where's my Nobel Prize?

He's a fashion model. Not kidding.

True but I don't think a high IQ got him that occupation though.

And iq of  carlsen is 220?

GM Hikaru Nakamura famously took the Mensa online IQ test and scored a very average 102.

     IQ has very little relation to chess prowess. Understand that the "I" in Intelligence Quotient does not mean what the word intelligent is defined as in the dictionary. IQ measures only those aspects of overall intelligence that can be tested and quantified--certain kinds of problem-solving ability. 

     Chess ability consists of many other factors, as well as IQ. The ability to concentrate to the maximum of your ability for long stretches of time. The capacity to learn the typical patterns and techniques unique to chess. The desire to compete and be your best. Calm under pressure. Most important are visualization (being able to "see" the position that will arise following a calculated series of moves and to further calculate from there) and visual memory (ability to accurately recall positions you have seen and studied before).

     High IQ will help somewhat in learning, understanding lessons, seeing what features of a position need to be considered, and low IQ will be a handicap in such matters, but lower IQ and greater capacity in the rest of the factors that make up chess strength will overcome high IQ and few other abilities every time.

     So, high IQ will be a small advantage if players are equal in all other abilities, but cannot be considered as a predictor of chess rating.

IQ is the key, Chess isn't for low IQ humans. we are the elite, we are bourgeois

I don't believe the studies are set up the right way. They should simply test the IQ of the top 100 chess players. I would expect that they average way above the average which is 100.

If starting score of high iq individual is 800, and rpy score 90 ( progress per year ) in ten years, if he practice every day, could achieve his limit score of 1700 ( his full potential ), and after that only to loop on that. In 2 years he could advance from 800 to 980, in 4 that would be to 1050. Now question is - how to calculate rpy score, because there is brain plasticity involved ( how early individual started practicing ) then overall IQ score which could variate 30 points or so during lifetime, in extreme cases even more. A lot of variables. One thing is for sure, when you position the chess board on the table, and you move furniture around it, that does not make any sense, I mean, who is playing what, where is a reason for that, where is a reason for a 90 RPY score that I just made up, score that is way more than optimistic? 

Yes, and there is a decay of RPY score, I would say aprox that if individual of iq score 160 have in first four years RPY 90, after that he would have maybe rise of 60 per year. There is a saturation factor. So he would not achieve that score in 10 years but maybe in 20. Yes, and I am talking about high iq individual that started playing chess in late adolescence.

If previous did not made any sense try this - Chickend duck and Wiesle, ducking the pleasers. Home mother, home, 2- points for griffindor dogs food. Here a rabbid ticked.

High IQ and lousy at chess seems kind of weird.  Maybe it should not.  But it does.
