This seems to be the issue - we're trying to study COVID, which affected literally the whole population of earth at this point, and we have no control group of people who have not been affected. People have gotten older, have gone through mass societal change, and any other number of things in between.

Also in every study we need a control group. How do you know for sure that the control group didn't get COVID. For all I know there is no way to know for sure you haven't been infected or sick of Covid in those 4 years, it is not like testing has been very reliable.

I know for damn sure I didn't get COVID yet. I don't go outside I don't work I haven't since I really graduated from high school years and years and years ago because I'm disabled and I got three vaccines so far but the rare time I leave the house for groceries I'm always fully masked in a 3M n95. I've never came down with symptoms and I live alone, I'm pretty ideal unless I got asymptomatic at some point.

Dont believe the 98% vax rate nonsense, in my circle of friends (including 4 doctors, 3 nurses) most got fake certificates. Dont be suprised that a bulk of the medical profession also did the same. I’m disappointed these professionals with very smart people just decided to bypass the mandates in order to keep their jobs instead of taking a firm stand for the benefit of society. Thats humanity for you. Lots of people…

Well, people self select their associates to a large extent. I’m sure bank robbers know other bank robbers, but that doesn’t make it a common characteristic.

No no no you got it all wrong about bank robbers. The last thing you want as a bank robber is to associate with other bank robbers regularly.

> Culturally we may want to imagine intelligence as something constant and innate to somebody’s soul, but in reality it’s innate to a fragile and fickle organ inside your skull. Which is also my issue with IQ tests and the relationship of the tests and what they measure. But that changes nothing: IQ tests are not supposed to measure _that_ variability of when you get sick. Or you wake up. Or you are drunk. It makes n…

One of the major uses of IQ tests is to measure brain damage, otherwise why would they be mostly calibrated in the downwards direction? Who do you think pays for these things?

> otherwise why would they be mostly calibrated in the downwards direction? Who do you think pays for these things?

I always assumed it was because there are people born with impaired intellectual abilities, and having some measure of how impaired they are would be significant for things like edibility for benefits and management of their condition (e.g. goals for the school system).

Unless you're teleporting or living there, getting from home to the office normally involves at least some exposure to sunlight.

Working from home doesn't mean you are forced or even have any incentive to stay at home all day long.

When did I say I was forced?

Are you actually responding to what I said, or are you just preemptively attacking what you (incorrectly) assume is an anti wfh statement?

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 lar…

> 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. Why? Whether someone has ever been infected is testable. About 20% of the US population had not had COVID as of some point in 2023.

which tests are you talking about? Antibody titers only work for a few months, and as far as I understand they’re the standard test.

Why do you believe that 20% of the U.S. population hasn’t had covid?

Maintaining a high level of civilization

So when civilizations collapse like a Ancient Egyptian, Rome, Ancient China & Ancient Greece. What it the IQ that also dropped to cause the civilization collapse?

The inability to recognise how an intelligence trait that correlates with pattern recognition might have an effect on being able to predict the long-term outcome of one's actions and provides the ability to work well with others in a very large group, which a civilization is, and instead defaulting to an ad absurdum argument shows where you might fall on the IQ spectrum.

I'd be interested in if there was a gene that significantly reduced covid infection likelihood - but somehow didn't affect much else, like other viral infection rates.

That would almost be a natural sort of experiment, to compare the IQ of these and other population.

Though, you would have to have enough people in this group, not be too rare. And it would help if there was already a large population that was IQ measured prior to Covid, and could be re-measured.

It seems unlikely that such a scenario exists.

I do not think IQ tests are meant or designed to measure effects from illness. We do not say that IQ drops when you are sick with the flu and have high fever that makes it hard to think. IQ does not drop when you wake up groggy in the morning up until you drink coffee. I am not sure why people use IQ here instead of referring specifically to brain fog and other symptoms of post-COVID infection. IQ does not drop when…

The tests themselves are misleading. If I do one sober, I have an IQ of 110, if I do it with my ADHD meds, it goes up to 120. Is that because the meds make me smarter? No, it's because I don't lose attention after 10 minutes of test and can concentrate until the end. However, the numbers imply otherwise.

Maybe yes, they do. Have you seen this famous article after GPT-2 came out? https://www.skynettoday.com/editorials/humans-not-concentrat...

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.

Your competitive performance level seems like a pretty objective way to test

There’s too much noise in the signal, and it’s also a skill gradient that I have been climbing for years. I don’t have enough samples to compare, and the samples don’t share enough similar context anymore.

If covid was a bioweapon, it was a very well-planned one.

Valid point, like minded people flock together. As long as we acknowledge other people exist, and their views / values can be different. Who am I to mandate how you should live? I also expect the same “live & let live” from others. The mandates interfered with the “let live” part since I know of a fatal vaccine sideeffect case.

Apparently you want to mandate that I live in a society that lets people remain unvaccinated. I don’t want that, but I do want to live in a society that doesn’t mandate sharing the public right of way with cars. It interferes with the “let live” part since I know of millions of fatal car cases.
