[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous] I mean what the kid is saying is exactly the original reasoning behind mitigation measures at the beginning of the pandemic. People on all sides claim science is on their side. I haven't seen the science that says masks are 100% ineffective. I have seen the science that says masks mitigate the spread. In fact, the first result from googling "do masks work with new covid strain" turned up a Jan 2021 article claiming masks are 79% effective. Its on the PNAS website (Proceedings of the National Academy of Sciences). https://www.pnas.org/doi/10.1073/pnas.2014564118 I don't know about you, but the antimaskers I talked with last year kept ranting about how the CDC can't be trusted because their science is politicized, but apparently now the CDC is pure science and not at all political. :roll: [/quote] You really can't be this dense? Do you read what you cite? It's a model by crazy mask evangelist Jeremy Howard, who used models (crazy when you assume that masks work, the models you build with that assumption baked in shows that masks work too). Notably, the study (from January 2021) says that there are no RCTs on masks. Now there are - the Bangladesh RCT, a huge 300K+ RCT that showed cloth masks were not statistically signficant and surgical only were (barely) for people 50 or over. This was all before a vaccine too.[/quote] I've never heard of Jeremy Howard. I didn't read the full article. My point was simply there is a lot of "science" on all sides. Would be nice if you'd provide links. [/quote] It's by far the highest value mask study because it has an actual control group. The mainstream media covered it as "masks work!" when in fact it said the exact opposite. The study: https://www.poverty-action.org/sites/default/files/publications/Mask_Second_Stage_Paper_20211108.pdf.pdf An explainer: https://www.medpagetoday.com/opinion/vinay-prasad/94399 Here's an explanation of the tiny # of cases prevented in a pre-vaccine environment by surgical for 50 and older: http://www.argmin.net/2021/11/23/mask-rct-revisited/ All very reminiscent of the latest CDC "study" that had a tiny footnote saying "not statistically significant": https://reason.com/2022/02/07/that-study-of-face-masks-does-not-show-what-the-cdc-claims/[/quote] Thank you. I appreciate this. I believe the study was about cloth and surgical masks. I don't know anyone arguing for those, but for kn95s or similar. So I guess I agree with you that cloth masks aren't effective, but there are better and more effective options.[/quote]
