      8/n Moreover, the authors have cherry-picked 3 specific places that appear to support their argument This is obviously bad science - what about the rest of the world?

      9/n What about Australia, where we've never had mask laws (and most people don't wear masks)?pic.twitter.com/CfulD3MWkq

      10/n Or South Korea, where masks have always been a major part of the pandemic response? Both of these are direct counter-examples to the arguments made in the piece, but are excludedpic.twitter.com/ESNAGvHb4C

      Careful. That's a major over simplification of what happened in S Korea.

      I don't disagree with your assessment of the paper, but showing that some places did well without masks doesn't provide any evidence against the paper's findings.

      And S Korea had a major gov intervention in late Feb to ensure everyone had masks.

      Sure, but my point is that if all you're looking at is a simplistic question of masks/no masks it's trivial to find counterexamples. I agree that all of these comparisons are ridiculous oversimplifications- that's the point!

      Note the paper claims that masks are effective, and maybe even *sufficient* to stop transmission. It doesn't claim they're *necessary*. A counter-example only works to show a claim of necessity is incorrect. The claims of the paper may be correct and still have counter-examples

      I'm not sure I agree - the paper explicitly argues that other NPIs are insufficient to "protect the public". I'm not sure you can interpret this in any other way tbhpic.twitter.com/ekit7hv5CI

      It's talking about the current NPIs in the *US* - it says that explicitly. And we can clearly see the truth of the claim in the US data. (Australia's approach of early border closures and lots of testing would have been great in the US, but too late to rely on that now.)

      I mean, the paper looks at a worldwide view. Semantics aside, I think it's pretty clear that they're saying that masks are the key NPI and that others are only useful as an adjunct

          I agree the sentence after the one you highlighted does imply that. For the key audience of folks in countries that failed to control the epidemic, it might well be true, but it also doesn't give sufficient credit to the Aus and NZ success so far.

          One key thing they missed in that conclusion is how well social distancing and masks work together. Masks reduce the radius of the germ cloud, making social distancing more useful. He was wrong to fail to note the important of distancing here, IMO.
