I think I'd attribute my newfound slowness to lockdowns, rather than COVID?

Lack of practicing talking and remembering stuff is bad for talking and remembering stuff, and it definitely happened long before I caught COVID, because I caught COVID super late

Is there any real world test where higher IQ people do better than anyone else deterministically? I am not talking about correlations. I am talking about people with higher IQ can solve X problem that people with lower IQs can't. Not the ability to spot back & white patterns on a screen. The riches people are not the highest IQ people The Noble Prize Winners are not the highest IQ people The best sports players are n…

Here in western europe IQ tests are unheard of. I never met anyone (people at work, family members, close friends, acquaintances, etc.) who has taken such a test.

(Czech Republic) I took one in high school, it was optional and paid, but sort of organized by the school. I think we took it instead of some morning classes. I got an official-looking Mensa application form attached to the results, so I think it was pretty legit. (never applied though)

Earlier quoted context omitted.

It's almost impossible to compare IQ tests across countries, because cognition test results are really only valid for people from the cultural context the test was written for.

If true, this seems quite damning for IQ as a metric. If the kilogram varied across countries, we would be in big trouble.

It's true, fwiw.

I wonder if covid infections, perhaps in rare cases the vaccines themselves, is to blame for the post-pandemic phenomena of ADHD medication shortages, the crime wave, school discipline (lack of), the so-called college enrollment crises (precipitous decline), and record low OECD test scores.All of these can be explained by dopamine dysregulation.

Most of those can be explained by the lockdowns and school closures, which made millions of lower class people even poorer and worsened their children's educational outcomes. More poverty + missed schooling = more crime, less college enrollment and worse test scores.

I doubt such a test is possible because IQ is trying to be a single number. Intelligence isn’t really generalized like that.

My question is. What is this Number measuring?

Why don't you crack open Wikipedia and start from there?

IQ metrics are continually damned. There is still no real consensus that they are useful at all. But the social sciences is filled with a lot of soft metrics like IQ because studying complex human behavior with hard science is very hard, and probably impossible.

My wife has postcovid and this is a profound effect. Yesterday she tried to add up a series of numbers by heart, and she simply couldn’t. For context, she’s pretty mathy and used to mock me for taking out a calculator or a spreadsheet for stuff like that. She also forgets everything, which is another thing she used to be great at. It’s pretty confronting, especially now that the idea that maybe this isn’t temporary i…

I have a very math-heavy competitive hobby which I found myself suddenly very bad at (relative to my previous performance) for 6-8 weeks after all my other covid symptoms were gone.

I appear to have recovered within 90 days, but I don’t know if I was left with permanent damage or not. I had no way to objectively test.

These "facts" pulled out of your ass are demonstrably false.

A typical IQ score for a mathematics PhD graduate is a couple of standard deviations above the mean.

IQ is correlated with intelligence, and higher intelligence enables greater achievements.

How long ago was she sick?

For me it's gotten better. I got sick in August 2021, the major effects (fatigue and brain fog) were most pronounced between September and February, and I've been steadily improving since. I think I'm somewhere around 80% pre-Covid capacity most days.
