Correlation between Elo and IQ

I would like to start some fruitful discussion about correlation between your chess score and your Intelligence Quotient. For some reason this topic always fascinated me. For many chess lovers -- not professional players but ordinary folks who  simply enjoy chess as an interesting pastime with friends -- playing chess well equates with being "smart". On the other hand -- IQ scores somehow became universally accepted norm for calling person "smart". Certainly, President Trump, for example, is literally obsessed with his "high IQ".  But IQ tests are essentially based on pattern recognition. Being a good chess player necessarily requires good deal of pattern recognition. Then what are your thoughts about correlation between your IQ score, your Elo score  (even unofficial such as here at chess.com) and you being "smart", whatever that might mean to you. 

According to my Elo, I hope it is a negative correlation. 

There's probably a small-to-barely moderate correlation between the two, but I seriously doubt that one necessarily implies the other.

Basically this.

Worth mentioning in these topics (which reoccur regularly) is that Kasparov's IQ was measured at 135.

No, I don't mean those click bait websites with celebrity IQs. They put him at 200 or some stupid thing. I mean his real IQ is 135.

You can't be an idiot if you want to be good at chess, sure, but much more importantly you need to be hard working and start young.

The best GMs make it at the ages of 12, 13, 14. Even if these kids had IQs of 180, it just means they're as smart as an adult. So the bar for GM, in terms of IQ, is easily as low as an adult's score of 100.

I think there is some bearing, especially in finding moves during a game. Like fast games for example, where you don't really know the opening moves, yet you come up with decent moves "over the board".

Chess is an intellectual function so there's bound to be a positive correlation. However, chess is also a hobby or interest and it's noted that people perform better when they enjoy something than in general, especially if they have a less generalised intellectual ability. For instance, darts players can subtract very rapidly but they might not be so good at other mental feats. Also, there's the matter of knowledge, where chess requires quite a bit and also dedication, which many intelligent people probably prefer to avoid. But overall, there must be a reasonably strong, positive correlation

I'd be interested in which test he took. It may be that he didn't take a properly designed IQ test. It's likely that someone of his chess ability has a somewhat higher IQ than that. For instance, some IQ tests are so badly designed and heavily biassed that they include general knowledge questions. If it was, for instance, designed in Russia, then he might not have such detailed knowledge of events in Russia, since he isn't Russian. That's quite a likely scenario.

ELO is based on chess skills only : Good tactics, thinking ahead x number of moves (greater the x, better the player), accurate playing without mistakes, etc.  General IQ is much more than that I would assume.  SO there is no direct correlation.

Tactics would be mostly to do with pattern recognition and some IQ.

Strategy, especially some deep moves would be mostly to do with IQ, and then tactical pattern calculation, I would think.
