I have a new article in the New York Times discussing lack of randomized trials for masks for source-control for COVID. In my newsletter, I discuss what this debate/debacle reveals, not just about COVID denialism, but also about our public health response.https://zeynep.substack.com/p/on-randomized-trials-and-medicine …

Here's the NYT article. There are many thorny issues here: and it goes beyond this administrations many obvious failures, and as we move forward, it's absolutely imperative that we do not fall into easy answers on what happened, and what needs to happen.https://www.nytimes.com/2020/11/06/opinion/sunday/coronavirus-masks.html …

Ah, the Danish mask study is out. Lots of people who don't want to read it will try to make a mountain out of it but, as I wrote, it doesn't and cannot test source control—the reason for masks—and it had problems with both statistical power and compliance.https://twitter.com/NoahHaber/status/1329079700988129282 …

But taken at face value, it would a great argument for increasing the quality of our own masks and for universal masking. (Because it would say cloth masks with poor compliance aren't enough to protect the wearer). Unfortunately, as authors note, too underpowered for conclusion.pic.twitter.com/ITbAJZ93ym

Replying to @zeynep
I wonder if there will soon be a Tufecki piece on best mask options / guidance for self-protection? Trying to figure out how to advise my parents who live in a part of the country with many anti-maskers and have been shocked by how hard good info is to come by.

N95/KN95... They are certified and with a lot of research and science backing their efficacy. It's the right thing for an elderly person around people who are not masked.
