Here’s some interesting points and ideas from a journal article published June ‘21. I’m sure it will be quickly buried as everyone resumes their partisan politics and personal attacks. I still thought it was informative nonetheless. There’s also dissenting letters posted to the article for some good counterpoints.

https://science.sciencemag.org/content/372/6549/1439

BLUF: “The nonlinear dependence of mask efficacy on infection risk differs from the assumption that the percentage change of infection probability as a result of mask use would be proportional to the percentage change of inhaled particle number (20). Under this assumption, wearing a mask would have the same effect on the transmission of a virus disease at any level of infection probability. Our analysis, however, shows that the efficacy of face masks depends strongly on the level of infection probability and virus abundance: Masks reduce the infection probability by as much as their filter efficiency for respiratory particles in the virus-limited regime but much less in the virus-rich regime (Fig. 3). Accordingly, experimental investigations may find low mask efficacies when they are performed under virus-rich conditions. Together with other influencing factors, like consistent and correct mask use (supplementary text, section S7.3), changes between virus-rich and virus-limited conditions may contribute to divergent results reported from laboratory studies and randomized controlled trials in different environments (20) (supplementary text, section S8). Notably, the increasing effectiveness of mask use at low virus abundance implies synergistic effects of combining masks with other preventive measures that reduce the airborne-virus concentration, such as ventilation and social distancing. For example, ventilation can change an environment from virus-rich to virus-limited conditions, which may be particularly important for medical centers with relatively high SARS-CoV-2 abundances (Fig. 2 and supplementary text, section S6). On the other hand, not only the efficacy of face masks but also the efficacy of distancing may be reduced in virus-rich environments (supplementary text, section S6). The more measures that are used, the more effective each measure will be in containing the virus transmission. If the inhaled dose may also affect the severity of infections (14), as is currently being debated (24), masks may still be useful even if the reduced dose still leads to an infection.”

The sun clearly moves across the sky. You can observe it yourself. Try it. . It’s obvious. Starts in the East. Moves toward the west. You can document it over a long period and determine it’s patterns. I mean it’s just common sense. The sun is moving. I’ve watched it move.

Also, some scientific studies that had more sophisticated methods than “common sense” determined that the Earth is spinning on its axis creating the appearance of sun motion. Those have obviously got to be wrong though. Just look at the sky!

We have a poor vaccination roll out, because of limited supply.
If you have a look at my post quoted below. I said Sydney wasn't locking down properly when there were 20-30 a day. They continued on the too little too late path to where they are now and estimates that it may get a lot more that the 600 a day now. They have now put in a better lockdown, but more needs doing. Other states have stopped the Delta. There are a few in Brisbane and Victoria that spilled over the border from Sydney. We will have to wait and see. It is a much more contagious variant. I don't know how the US will go with the stand back and see what happen approach.

Our Adelaide 7 day lockdown was 3 weeks ago. We eradicated the outbreak and getting back to normal. We still have masks in some places. Melbourne and Brisbane are getting on top of cases as they arise. From the spillage from Sydney. Sydney still hasn't locked down properly and cases are growing. Like the US, each state here is in charge of their own health orders.

I’m sure enough of the citizenry would feel strongly enough about it that they’d volunteer for their local Mask Enforcement Force.

No they wouldn't. That's the best part about the Karens and Bobs. They crumple like a cheap suit when you tell them to fuck off in colorful and assertive terms. If they can't get the police power of the state to force people to do what they want, they just sulk about in the corner.

Would more vaccines help? Highly vaccinated countries like Israel and Iceland are still having outbreaks. What’s the end game? When will a covid case not trigger a paramilitary lockdown?

The liberals are now saying that babies don’t need to see faces and that full-time mandatory education is only a creation of the last century and our ancestors didn’t need it and they were very successful without it.

Also, masks work.

These are not gotchas or new information. It is common sense that an N95 is more effective than a cloth. It is common sense that a tight fitting mask is more effective than a lose fitting one. No one is surprised that a well ventilated space is better than an stagnate one or that the viral density in a space is a key component. These stories do not help your anti mask stances. It just proves that poor use, and less infective products are the cause of some of the varying results in mask use and case rates in different places. Using the articles and studies I have seen here might lead someone to mandate only N-95 masks and prohibit occupation of spaces without a certain level of ventilation. I don't think that is what you want.

To some people on this thread who really think these things work, this might be new information. And again, if you don’t care, why comment? You’re not picking up what I’m putting down, and that’s fine. Just seems like a lot of effort to say TLDR. But I guess boomers have lots of time on their hands.

As to your last point, if that does happen, that means “the scientists” would have to admit, in a big and public way, that they’ve been wrong this whole time and weren’t actually following the science. But I don’t live in a socialist state, so I’m not super concerned about it.
