Happy to discuss the evolving nature of science, poor communication from government & medical orgs, & the lack of consensus surrounding mask usage. But I’m not sure what you’re getting at by pointing to a thread (based on CDC guidelines) about the need for clear communication.

That's why I didn't single you out but you realize every single thing you claimed in that viral thread (and I tried to tell you otherwise) was wrong? The alleged increased risk, false sense of security, lack of benefit? Every single claim you made except shortage was 100% wrong.

Just to be clear: Those claims claim from the CDC. And yes, most turned out to be wrong. Also, at the time, there was little (if any) distinction between protecting self vs others. But do we have research from US showing that mask usage doesn’t confer a false sense of security?

Yes, they came from the CDC and they were all wrong. That's my point, and I kept trying to talk with people like you to point to the evidence that they were wrong. And for lack of false sense of security? Yes, we have decades of evidence from many other safety devices.

As I very publicly argued back then, false sense of security is trotted out against every safety device/intervention (seat belts, helmets, safe sex) and has been researched to death. You can find individual examples, but it never overwhelms the safety benefit. But that's not all.

Those behaviors (helmets, seat belts, etc) are primarily aimed at personal protection, not protecting others, though. The research may very well translate, but I don’t know if we can say that yet?

We already have experimental confirmation. I'm not saying we shouldn't keep an eye out, but what are they going to do with this false sense of security that will override the benefits? It's a very similar argument to ones made against seat belts.https://twitter.com/zeynep/status/1269364962213990401 …

zeynep tufekciVerified account @zeynepI've been arguing for months that the most likely outcome of masks would be INCREASED adherence to distancing—because that's what social science suggests. That baseless "false sense of security" claim had no evidence for it. Now, experimental confirmation. https://twitter.com/Babak_Javid_Lab/status/1269312406120996864 …Show this thread1 reply 0 retweets 2 likes -
Plus, wear masks if you are sick, um, of course that won't work. Stigma and solidarity are very well-understood concepts of social science. Masks only sick=stigma. We have a lot of research from TB. Everyone wears them=solidarity and signaling of the emergency.

It's terrible because it's so consequential. I think our evidence for benefits of masks has greatly increased since March but, even back then, lack of evidence for harms should have meant we should have gone ahead. Fewer cases=less PPE needed so helps shortage, too. Alas.
