You're citing papers which came after the public health authorities decided it would work, not before. Before the sudden about face the WHO had guidance for how to handle a respiratory virus pandemic. It said don't shut the borders, don't try and socially distance, don't restrict travel. All that was torn up and replaced overnight.

But there's nothing to speculate about here. Fauci explicitly told us the idea of social distancing "just appeared", which is easy to confirm just by looking carefully at the timelines. There was no evidence that led to the policy, it was just invented out of thin air. Not my claim: his. And then because academia is corrupt they promptly produced reams of papers claiming it worked great, although real world evidence showed it didn't. You can read these papers for yourself to see how motivated the reasoning is.

> The reality is we didn’t have high certainty on most of these questions

That's correct! There was uncertainty because there was no evidence these policies worked, which is why people got pissed off when they were presented as 100% dead cert things that only crazy Anti Science People could doubt. At no point did public health officials say, well, this might help or it might not so we'll leave it up to the citizens to decide what to do. Everything was 100% critical and had to be forced via law overnight because Science™.

You're trying to excuse what they did by saying they had to make decisions, but they didn't. They could have simply admitted they didn't know, done nothing and left it to individuals and their doctors to decide what to do for themselves. They chose instead to impose policies on the whole world by force, justifying it by claiming they were doing solid science when in reality the policies "just appeared".

Social distancing dates back literally to the 14th century dude. It is a standard tool in the contagion toolbox. The null hypothesis is that you would apply it to this contagion too until you have evidence otherwise.

No, he told us the number 6 "just appeared," as compared to the numbers 5 or 7.

Please link to said papers.

Again, you're just wrong on all the facts. There are plenty of good reasons to have defaulted to social distancing. Not only was this logical at the time, but all evidence still points to it having been the correct decision in retrospect. I know you're in the habit of simply dismissing countervailing evidence, i.e. you've decided to give up on yourself, but there is literally centuries of evidence behind social distancing.

The fact that people caught COVID while far away from each other literally isn't even a dent in this body of evidence. And I don't mean that because it's weak evidence against it, but that it's not even evidence against it. Nothing about the social distancing hypothesis suggests one cannot get sick at a distance.

Thank you for providing all of your evidence (none). It is illustrative for other readers.

Details matter! Medieval quarantine ships worked against plague and cholera because those pathogens spread very differently to aerosolized coronavirus, and had very different mortality profiles. You can't just lump every possible pathogen into one bucket labelled "contagion" then claim you now understand it. That's exactly the kind of broken thinking and fake expertise that led to so much loss of trust.

Your choice of papers is an example of this problem in action:

https://pmc.ncbi.nlm.nih.gov/articles/PMC2966666/ - it's about school closures+flu, but people got upset about school closures because unlike flu COVID overwhelmingly affected the very old and very sick, so it didn't make sense to close schools to protect kids. It's also the kind of analysis that's likely to be P-hacked.

https://pmc.ncbi.nlm.nih.gov/articles/PMC1929395/ - a mortality report on Asian flu. What point are you trying to make with this paper? If it's about school closures again, it gives attack rates of 59% for asian flu in schools, but attack rate for SARS-CoV-2 in schools was measured at more like 4% (again, with mild cases that didn't endanger the kids). You can't reduce infectiousness and impact by 10x+ and say they're the same.

https://pmc.ncbi.nlm.nih.gov/articles/PMC2808319/ - SARS-1 this time, which is at least a coronavirus! But it's also one that had very different mortality/spread profiles to SARS-CoV-2 (I don't personally think it should have been called SARS-2 because of this difference, even though they're closely related otherwise). It's an observational regression analysis again, so low quality evidence, but what it shows is that even for SARS-1 where quarantine was more effective the number-needed-to-quarantine was uselessly high, with 7.5 infected needed to be quarantined to eliminate just one case. That's completely unworkable especially as social distancing isn't even close to the same thing as an actual quarantine. This paper is the sort of analysis that led to the pre-2020 WHO recommendations against quarantine and travel restrictions for RV epidemics, and supports what I'm saying: they could easily have known social distancing wouldn't work, and probably did know.

Again: what you said is there was no basis to believe social distancing would help.

I have just linked to basis to believe exactly that.

Sure, it may have turned out that COVID-19 would be totally different (though it didn't -- we now know empirically social distancing was helpful here too), but even if it had, clearly there was evidence to assume from the start that distance from infected person would be a component of infection rate.
