Totally off -- Rating = (IQ * 200) - 800 which supports Fischer's 180 IQ claim (giving him a 2800 rating) and explains why chess.com starts everyone at 1200 (corresponding to the average IQ of 100).

Of course it does - it was produced by MIT.

The formula must assume that people live to only play chess barring all distractions, culture issues, exposure to the game and lack there of, monetary issues, ability to travel to countries that host FIDE tournaments, and pretty much all other humanly possible reasons that a chess rating may be lower or higher than it could be.
Ok.

Maybe... your math seems to indicate it ^_^
What is a math ? Didn't even know I had one ? So , I have an IQ and a math , but what do I do with it ?

Don't worry about it, you wouldn't understand.
But hey, then again, neither would I since my IQ is only 8.15. Actually, I had a birthday, so now my IQ is 7.
I thought IQ stood for Indian Queens , a kind of reversed QI . So you need this math thing to rate something ? Do I have that , a rate ? I'm asking you because I think you must be smart , I mean 8.15 is more than -23 because there are more digits in it.

I am 48 and have an IQ of -23 but have no rating. My opponent is 33 years old and has a rating of 2247 but has no IQ.
Who will have the highest probabillity to win a game played between them?

read again. its only valid for ages 10-50
I know that. But who has the highest probability to win a game played between them ?
To satisfy you , I will lie and tell that I'm 50 , no 49 to be safe. I will tell my secretary to edit the original post.

I think it's quite obvious that it's a mega-stupid formula that just doesn't work. There is no correlation between IQ and FIDE rating at all, so no formula can work.
It's meant to be a joke.

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.
Anand (2775, 40 yrs old): IQ = 147.27
Carlsen (2870, 23 yrs old): IQ = 159.80
Rating 1600:
10 yrs old : IQ: 117.5
20 yrs old : IQ :98.75
Rating 2000:
10 yrs old : IQ :137.5
20 yrs old : IQ : 118.75
Rating 2600:
10 yrs old : IQ : 167.5
20 yrs old : IQ : 148.75
