Can wearing or not wearing a mask to protect oneself from covid-19 be regarded as an example of natural selection at work? Where mask wearers are most adapted to survival in their environment and non-mask wearers are not?
Anti-maskers are killing their parents, not themselves.
So - no. Mask wearers aren't going to experience any difference in death rates in the vast majority of places because COVID deaths have already ended. And of course, when they were occurring, there was a lot of bad reporting there which conflated people who were dying anyway with people unexpectedly killed by the virus.
If evidence based medicine isn't an advantage then it's down to luck?
The best is remedies that have both. But don't think evidence without good theory is fine. I'm not sure it's even that much better than theory without good evidence.
That's the reason we need randomized trials. How do masks work outside of the lab?
Also, it isn't accepted science that Covid-19 infects through aerosols.
There is only one study that looked at cloth masks and it was completed in 2015.
> And IMO it's completely wrong to say we have no evidence tht masks work.
I never said that. I'm saying that a high standard of evidence has not been met and there isn't much interest in running trials on cloth masks. The only one I could find is in Guinea-Bissau.
