If this is true, you should expect results to be the same across countries, and the measurable drops in IQ should correlate to infection rates. Five bucks says you won't find that.

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.

It's not about comparing IQ between countries, it's about pre covid IQ scores with post covid IQ scores within the same country

The title is misleading, at least on the IQ claim. The underlying study was observational and did not claim causation. Medical journals and their associated media summaries are awash with low-certainty studies that get de-nuanced and overhyped. These studies are relatively easy to do - not to denigrate the work put in by the original study authors (it’s not their fault the press sensationalize their work). But for st…

I experienced some limitations of cognitive abilities but not sure was it due to COVID or some sort of depression

That settles it then. Causation proved.

If you accept "cognitive impairment" as a drop in IQ, then this meta study seems to find that globally after infection, and I claim my $5:

https://pubmed.ncbi.nlm.nih.gov/34973396/

> A significant proportion of individuals experience persistent fatigue and/or cognitive impairment following resolution of acute COVID-19.

> Ten studies analyzed data from Italy, nine from Spain, eight from the US, seven from China, six from the UK, three from Denmark, France, and Norway, respectively, two from Australia, Austria, Brazil, Canada, Egypt, Germany, Israel, Russia, and the Netherlands, respectively, and one from Belgium, the Czech Republic, England, Faroe Islands, Iran, Japan, Mexico, Pakistan, Singapore, Sweden, Switzerland, and Turkey, respectively...

Has she been vaccinated? How many times?

Australia has a population of 26 million, longer life expectancy than the USofA, and comprehensive medical records going back many decades. With ~98% of the population COVID vaccinated multiple times any vaccine effects would stick out like dogs balls. If anyone wants to posit "vaccines cause { stupid | strokes | etc }" Then such correlations should be readily apparent in the before | after records of 26 million test…

Australia's excess death rate is still higher than pre-covid: https://www.abc.net.au/news/2023-12-20/mortality-rates-austr... . If the Australian government released the data it'd be trivial to identify whether these deaths were concentrated in the vaccinated or the unvaccinated, but so far it hasn't released such data (if it even possesses such data in aggregate format).

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…

This is like saying that since the tallest people are not the best basketball players, height in basketball doesn't matter.

I would be careful with some of the self-help groups. They can reinforce symptoms rather than improve them. A case in point is a friend of mine who thought she had post-covid symptoms and cognitive decline. She went to a similar group and found a lot of very miserable people with depression. When talking to them they had similar stories of lost relatives, lost jobs and general social decline. But all had a common thi…

Yeah, well aware. Fortunately her group is an impressively can-do-attitude bunch, and she’s getting very concrete ideas from it. I think it helps that it was organized by a government-y instance who did some checking, and isn’t some facebook group turned physical or sth. (Also, no drinking. That would be madness. Nobody in that group drinks at all anymore, it would set back their recovery by a lot) For example, she h…

Don't worry about it being awkward, there are many reasons for being in a wheelchair besides not being able to walk at all. I mean, the fact that wheelchairs are provided at the entrance indicates that there is a demand from individuals who can walk to access them.

> There are studies that have been done comparing people who had COVID-19, versus people who didn't, and then gave them cognitive testing to measure their ability to cognitively process information and test their IQ. And there's very clear differences in the IQ of people who had been infected with COVID-19 versus people who did not. Even mild COVID can give people about a three-point loss of IQ.

Hasn't pretty much the entire population of earth been infected by COVID at least once at this point?

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…

Has she been vaccinated? How many times?

Yes. The symptoms started the day after her 3rd jab. Basically she got that “woa i got jabbed yesterday and feel like shit” thing many people got, but then it just never went away. She got covid 1.5 months after that jab so there’s no telling whether the jab or the covid was the key cause to her long-time postcovid. The covid infection itself wasn’t particularly heavy.

We very much want to stay out of the “covid vaccines are evil/fantastic” debate. It’s fruitless. I will not respond to any comment suggesting that somehow we’re wrong and well actually, it couldn’t have been caused by the vaccine / the covid infection, or that postcovid is an imaginary disease.

Thank you for your honesty.

Maybe one of the downvoters would like to explain why he / she finds this question so emotionally triggering.

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

Erh, where in the world?

Evidently I am an outlier? I was asked to do it twice as part of ADHD diagnosis.

Once in the UK as a pre/early teen (2003~), and once in Sweden to be rediagnosed via a private company named Modigo (so, now I am not sure if it's standard as part of the healthcare system here).

Since I was 2/2 and that was 100% of my experiences throughout two countries, I thought it was the standard.
