I am not stopping a defense of the Cochrane review. It’s the best current study we have and it announces that it’s not clear if masks work. If we don’t know if they work, why should governments keep mandating them? They shouldn’t. Full stop.
Regarding Japan, here’s an article by the NYT: https://www.nytimes.com/2022/01/24/opinion/japan-covid.html?smid=nytcore-ios-share&referringSource=articleShare they talk about Japan’s success. Notice how masks do not feature heavily in the article.
Here’s another one that places your claim in doubt: https://www.cfr.org/in-brief/japan-covid-19-pandemic-response-restrictions-two-years
Finally, the total number of deaths in Japan and the US differ widely in large part because the two populations are, broadly, very different. COVID disproportionately effects overweight people. Ask anyone that worked in the hospitals during peak waves. The simple fact is that fat people don’t do well with Covid. Now ask yourself, is there an equal number of overweight people (%) in Japan to the US? No. People in Japan are far less overweight than people in the US. It’s no wonder, therefore, that the US fared worse because it’s population is move overweight.
The point of those links is to show that masks are not the answer.
Ultimately, we are concerned about COVID causing deaths and serious harm. It does this for overweight people. Other people don’t suffer nearly as badly and COVID typically presents as a mild to mid level cold or flu. Consequently, it’s really not as big of a deal as we’ve been making it out to be.
COVID sucked mostly because of poor policy. I lived in a Canadian city with a strict masking policy and high compliance. The spread of COVID was massive. The hospitals in Canada were full and fucked way before Covid, so a few extra admissions completely broke their fucked up system.
I’m no longer convinced the whole world had to shut down and mask up. COVID policy fucked over the economy and people’s’ well-being. It has especially negatively effected those most in need.
Ultimately, I think people should wear masks if it makes them comfortable. I find masks to be uncomfortable, ugly, and ultimately anti-human, because I think the face is an important part of humans. Some people don’t seem to think this, however, so I understand I might be among a minority.
Finally, isolated physical tests on masks don’t represent well what happens in the real world. I don’t know about you, but I sure as hell wasn’t hermetically sealing the masks to my face and I didn’t see anyone else doing it either. The real-world usage simply wasn’t effective. It was political.
