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.

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.

Western Europe is a big place. I guess it also depends on whether you only count tests conducted in a professional setting. Here in Germany, i guess at least 20% of people between 20 and 40 have taken some kind of IQ test, e.g. online. Not everyone might admit it because it could come of as a little "vain", but there are even IQ test shows on popular TV channels (Sat 1, RTL 2) where the viewers do the test. They run them at primetime every few years.

It's supposed to measure general intelligence (supposing there is such a thing, which I doubt). Correlation is the only thing it's trying to do.

If you had a specific test like you're after... that would be by definition not general intelligence, but rather some specific intelligence.

Neuroinflammation is a poorly studied area and one likely cause of brain fog and mecfs/long covid symptoms. Jarred Younger [1] is a researcher studying this and has a youtube channel [2] where he discusses his latest work. If you're interested in this it's worth watching!

Also please ignore anyone that posts 'oh its just X' or 'just do X', whatever X may be. This is a complicated medical mystery that millions of patients have suffered from for decades if you include mecfs and postviral conditions. There is no X, patients have tried every possible X. Anyone who tells you its just X is revealing their lack of understanding of the issue (this happens every time this subject shows up on HN and elsewhere).

You have to take an IQ test as part of an ADHD diagnosis. I genuinely don't know why, but you do have to.

This is not correct. At least not in the U.S. as a whole.

It may of course be true where you are.

The DSM does not even suggest an IQ test as part of the diagnostic.

Knowing 6+ people in several states with ADHD diagnoses (some as children, some as adults) none have had anything beyond questions with their physician… or diagnoses by a psychiatrist after starting therapy for a different issue.

IQ tests being useful and IQ bragging or judgement being stupid are not mutually exclusive

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.

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.

Woa this is a great thing to hear actually. She got sick January 2022 so a bit over 2 years now. Our current fear is that this is the kind of thing where either you recover within ~2 years or it’s forever. Appreciate your story and will share with her.

Her other symptoms, particularly the fatigue, do seem to improve (though the weather and being about to be outside impacts it a lot, so she had a huge setback 2 winters in a row now), though very slowly. I like hearing that for you the brain thing has improved over time too, thanks!

Has she been vaccinated? How many times?

Erh, where in the world?
