Relationship between Chess rating and I.Q?

You don't seem to understand what we're saying and everybody's wrong whether you agree with them or not. You seem to have been copying what I've written and then claiming that I'm copying you. You haven't added anything new and you seem to have it in for everyone, so I got fed up. I'm sure you're okay as a person but it doesn't come across. Also, you seem familiar to me but I don't think we've talked for years. You seem to like 1950s American slang but you have a British flag. Where are you from?

Chess does not mean high iq

I was born & have lived in UK my whole life but my mothers father was American that lived in North Carolina, he was a fighter jet pilot that moved to the UK for a while when he was with my nan. When they split he moved back to USA.... I have never fitted in over here, never felt at home. I prefer yanks cause overall they seem far more intelligent to me Anyways nice to meet ya, see ya around on here. Take care

Sorry I got annoyed. All the best.

There most definitely is a correlation. It seems that all top players have strong pattern recognition. My theory is that players with strong pattern recognition often score high in other categories of iq tests. There are some people who are just outstanding in that one category though, thus scoring low on iq tests but having extraordinary chess ability. Take Hikaru for example. I believe I am somewhat the opposite. I consistently score above 135 on iq tests and, with a bit of luck, have scored 147. However, I am very weak when it comes to pattern recognition and have never crossed 2400.  

Bingo

It's from decades of practicing and studying chess.

It's like saying, "It seems all top weightlifters have strong muscles".

Sure. Because they've spent years and years lifting weights ...

There's bound to be a positive correlation between IQ and chess rating, Ziryab's opinion notwithstanding. It's just that there are several other factors which have a bearing.

However, if someone said that the stupider people are, the better they are at chess, that would seem a bit wrong, wouldn't it? So that demonstrates that ability tends to increase as IQ increases, given that all our mental attributes affect our performance at cognitive activities. It's just that many people don't understand complex functions with more than one variable.

That correlation is most likely so weak that it has no explanatory value. But surely it exists.

I also bet that there is a positive correlation between height and chess rating.

I would say negative. Short people are insecure and need to defeat people in other ways than physical.

People who think there's no or a very tiny correlation aren't thinking straight. Possibly they can't help it or possibly it's also an insecurity thing.

What do you mean by the height part? How would that give you an advantage (if ever so sleight) over short players?

IDK MAN

hi!

• Males are on average taller than females. Males are on average better chess players than females (*). 
• Twenty year olds are on average taller than ten year olds. Twenty year olds are on average better chess players than ten year olds.
• Well nourished individuals are on average taller than under nourished individuals. Well nourished individuals are on average better chess players than under nourished individuals.

Et cetera. Correlation does not equal causation.

(*) Not really -- https://en.chessbase.com/post/what-gender-gap-in-chess

A good scientist will always look at causation as the first and most likely possible cause of correlation.

Very short chess players have trouble seeing over their row of Pawns.

When I was younger, I was so "hip" that I had trouble seeing over my own pelvis.

Did you wear loons??

If you're not careful I'm going to change into me 50 years ago ..... long hair, stripey blazer and a gormless expression. I was an anti-hippy except I came just after them. The opposite to antipasto.

IQ has many facets, only a few of which are skills needed for chess.

Well, for one thing, young children tend to be short and they also tend to be not very good at chess (but some of them are). That alone shifts the averages a bit.

My point is exactly that a very weak correlation is most likely completely useless. In my opinion, this is true for IQ as well.
