I have an iq of 39 apparently...
IQ and FIDE rating


University of MIT (Merely Incompetent Teachers) publish first ever formula for calculating IQ score from an official FIDE rating!
Here it is:
IQ = (FIDE rating/20) + (375/age in years)
Unfortunately it is only valid for ages 10 - 50.
Magnus Carlsen's IQ is therefore around 160.
based on my iq i should be 2080
maybe because of school its lower than that

The guy closed his account a few days after creating this topic, but somehow people are still responding to it 12 years later.

This is so cool!
age in years = 7500 / ( 20 * IQ - FIDE rating )
Every time I lose a game, I get younger!

I'm only responding to it because someone else did. You, for example.

There have been quite a few studies re this issue and none, as far as I know that didn't have only children as its subjects, this because you need a large group and they need to have had roughly the same amount of experience (at the start of the study) with chess. The conclusion is usually that, while intelligence is a factor (how could it not be?), it isn't the only factor, or even the most important factor. *Experience* is, by far. And there is a third factor, not at all to be dismissed: interest/enthusiasm. In fact, in one study, - I'll look for a link and add it here (I got it from a chess.com article), it was found that high intelligence and chess skill were negatively correlated. The more intelligent they were, the less likely they were to reach high skill levels during the course of the study, not more, not at all the expected result. Wanting to understand this, they interviewed the children and eventually concluded that, at least in this group, the more intelligent a child was, the less interested and less motivated they were, most especially to *study* chess. The least intelligent, relatively speaking and up to a degree, both played more and studied more. Why? When interviewed, this group almost invariably expressed more concern about their rating and were more likely to think rating was important.

I worked the formula in reverse (known IQ and x is FIDE rating). Turns out, I'm a grandmaster. I'll take the title without ever playing a tournament. Thank you!
that is a stupid formula it does not even work. my real iq is somewhere around 150
140 IQ is the max traditional test you can get to you, buckaroo, it sure doesn't work, but your IQ is not 150.

My IQ is like 147 but my current rapid ELO is 588 (highest is 782)
does that mean I’m 6.94 IQ, which is a complete idiot that can’t even survive?
