Yet another observational study with no real comparison. The REACT dataset used by the study relies mostly on self reported surveys and data from people sick enough to go to the doctor. This has obvious problems.

The idea that there is a control arm of people who haven’t gotten Covid large enough to power a real control here is farcical. Again, a problem of self selection for people committed enough to maintain a large level of isolation for multiple years.

Any causal study here should be looking at a differential in pre and post covid cognitive scores with a control of known uninfected participants in the same time window.

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.

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 not the highest IQ people

The best mathematicians are not the highest IQ people

The best musicians are not the highest IQ people.

None of the these have excellence that can be deterministically determined by IQ. So what exactly is it good for?

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 is taking shape.

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.

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