chess and iq = fish and apple - they both are to eat but completely different things ( animal and fruit vs test and game) at the same time and meant to enhance your perception

@FakeCrabMeat Yes, that would very interesting! It seems that I.Q. (in the old, ratio-like sense) was measured to linearly increase from ages 6-7 to 12-13. We also known it stabilizes after 16, but what happens in adolescence is still a mystery to me.

I believe Kasparov's I.Q. was calculated via the exact translation in the link I provided in my post, which functions pretty much the same way as the formula I suggested for FIDE Rating (from now on I'll call it Melão's formula) does, but not taking into consideration inflation. Kasparov actually took two real-life I.Q. tests and scored 123 and 135.

"Wow, from 123-135 to 190?" Yep.

In fact, firstly, nope. If I'm not mistaken, both tests used the Stanford-Binet scale instead of the Wechsler scale, to the actual results were 122 and 133 (the difference is negligible, so it doesn't matter).
The 190 was a translation done using the Stanford-Binet scale, so it actually means 185. In Melão's formula, the result is 183.
In my lichess scale, it gives exactly 160.

Secondly, it doesn't matter at all.
One thing we have to keep in mind is that the ceiling of an ordinary I.Q. test does not go above 135, because the test is not aimed to measure levels of ability this high. It it only appropriate for discriminating between people within 2 standard deviations from the mean.
For abilities such as Kasparov's, one needs a much harder test (for example, The Power Test http://miyaguchi.4sigma.org/hoeflin/power/power.html). What matters is not that Kasparov scored around 130 on a ordinary I.Q. test, but that he's the youngest ever World Champion, was the World Champion for 15 years and achieved a 2850 Rating.
Thus, for Kasparov, a 185 figure is much more believable than a 122 or 133 one.

I would love to!
At the current state of affairs, academia is out of the question for me: classes were canceled (again, 3rd or 4th time since I entered) a month ago. This happens with surprising frequency in my university (Rio de Janeiro is politically destroyed), so I cannot expect anything great therefrom.
Academically, I'd like to study more abstract topics rather than applied ones, but if I spot the opportunity, I'll surely take it!
What about you?

@Acoffe I study Psychology, Behavioural Science and Philosophy under a BA (Psych). It keeps me busy. I plan to do Clinical Psych as I have a background in Mental Health Care and pretty much want to do a job where I can sit in a room and rack brains all day everyday. But all is good, unfortunate about the political issues in your country. I'd love to see SA someday when I'm not a broke and busy student haha

@FakeCrabMeat Wow, that's actually awesome! I'm very interested in Philosophy and Neuroscience, but it will have to wait... maybe one day.
Thanks. I hope you come, there are many beautiful places in Brazil to enjoy! I'd also love to to visit Australia, but, again... it will have to wait haha :)

Anyone who believes chess has anything to do with intelligence receives an automatic deduction on their IQ score. Depending on the severity of the misconception, the resulting score is between moron and idiot.

The stupider you are the more likely you are to be good at chess.

Kasparov in no where near 190. And number here bit misleasig there are at least 3 different test set giving SD of 16,15, and 24.
"Some sources give Garry Kasparov, a renowned chess player, an IQ between 185 and 190. But in 1987-88, the German magazine Der Spiegel went to considerable effort and expense to find out Kasparov's IQ. Under the supervision of an international team of psychologists, Kasparov was given a large battery of tests designed to measure his memory, spatial ability, and abstract reasoning. They measured his IQ as 135 and his memory as one of the very best.

So he intelligent But barely above Mensa limit. Rare but I meet people above mensa limit every day

Would be careful to transfer „island-talent“ (hope u understand, edit: probably better „insular“) to „intelligence“.

You always talk of GK: Kasparov was god on the board but he spoiled practically everything outside the board. Where’s the intelligence gone?

Likewise, claims of 180 were made for Fischer. Whether he ever took a test is highly debatable. It was all PR by is handlers. Possible he took a non standardized test in high school, the results were never made public. His teachers all recall a very poor student, who barely scratched by passing their courses.
