What does your chess rating say about your overall IQ?

According to Le Hoang Minh Son, this is an estimation for the correlation between your chess rating and your IQ:

*Considering you play chess 2 hours a day and do not participate in professional chess, this is the connection between the rating you gain in 1 year and your IQ, assuming that your beginning elo is 0

-From 0 to 800-1400: 90-110 IQ (average intelligence)

-From 0 to 1400-1600: 110-125 IQ (above average intelligence or smart)

-From 0 to 1600-2000: 125-135 (moderately gifted or very smart)

-From 0 to 2000+ : 135-160 (genius)

P/s: while this might not apply to everyone, it is generally acceptable.

Chess ability IQ based on one's rating is likely to be difficult to assess, my over the board rating at my peak some 15 years ago was 1927, had long break and came back 5 years ago playing over the board and got my rating up to 1730 I started training to play Blindfold chess and slowly over time got myself up to playing 6 boards blindfolded then dreaded covid hit and ended my over the board chess playing now only play for fun on 3 online sites!?

There is no such correlation between IQ and rating progress.
One deciding factor is how much work you put into it, here assumed 2 hours / day Even so , is that 5/6/7 days per week?
Another deciding factor is what exactly you do. Some chess related activities are worthless for progress: playing speed chess, analysing won games, opening study, watching videos...

Such correlation is not universally accepted or scientifically proven.

'Overall IQ' is a misnomer. IQ is an aspect of intelligence.

I thought that IQ was for cognitive ability, not intelligence

Vast majority of chess is memorisation, IQ is bollocks in regards to chess relationship, that's why kids are so good, they have no responsibilities in life and plenty of time on their hands whilst soaking up new info like a sponge. Adults do not, starting at adulthood therefore much more difficult. All the openings and end games have been determined, just a matter of learning them, middle game is just coming up with simple plans and spotting tactics, again you need the time to practice, the more time on your hands, the better you generally are at chess. People trying to think they're very bright whilst grinning like a Cheshire cat just because of some arbitrary numbers invented by some chess elo geek, are amusing You don't have a PHD, the only PHD you do have is in procrastination, that's it.

Whilst chess elo does not directly correlate with intelligence, there are many people in the world that think so and that gives you something to brag about to those who don’t know any better

It says absolutely nothing because it doesn't specify which rating. It might mean bullet.

There are so many different aspects to what one could consider intelligence. There are many animals who are more capable and can calculate faster than a human. Squirrels can remember where their nuts are better than most humans.

Some people have excellent memories, but they may have relative difficulty processing data into a strategy or tactic.

That's the beauty of chess. It challenges different aspects of how our individual brains work. Figuring out how to improve certain aspects can have a direct affect on how we play the game, let alone other facets of our lives.

Some of us; ie. Magnus Carlson, may have brains that are innately better than most of us could ever possess. Somewhere in the continuum are the rest of us, moving back and forth along it.

Wdym humans can’t remember where their nuts are😳

Nothing--there is no direct correlation between IQ and chess. I've seen brilliant people suck at chess and average Joes become strong masters.

They weren't average at chess, were they; and chess is just one potential measure of intelligence. By the same argument, Hikaru doesn't have an IQ of 103 (obviously!)

Chess is no measure of intellect whatsoever, as Fischer said, it's nearly all pre-arranged, it's nearly all memorisation, at the top level especially, barely any creativity left, you watch titled tuesday, in some lines in less than 10 moves they're declaring it's a draw FFS, because both players know the theory so well there's no way either side would win.

An IQ test is simply the best way of determining intelligence, because it mostly deals with logic.

Chess is no barometre for success when it comes to intellect prowess - it's simply a glorified test of memory.

It doesn't seem so to me.

No point in going into it too deeply although he is reputed to have had a fairly high IQ. He should have understood that all aspects of intellect correlate positively with each other to some extent, so that a good memory tends to correlate with other mental abilities. I wouldn't place much store by what Fischer thought, since he was very obviously messed up. That means that his application of his mental abilities would be subject to his mental biasses.

There is a correlation between IQ and chess skills. Although it is a little more complicated. Only a certain part of IQ is largely relevant to chess. If someone scores high in this part, there is a high probability that they will score high in other parts as well. However, it is not necessarily the case. There are individuals who might score average in overall IQ and still score high on this particular part. This may be the case for Hikaru.
