You can’t prove a negative. The burden of proof goes in the other direction. And no one is trying to prove they *don’t* work. It’s that we need proof that their benefit exceeds their risks.

Evidence of their risks are non-existent. Stop doubling down and face the reality that you were totally wrong. Own your mistakes.

“Totally wrong” is a very strong position to take. Most of my positions are tentative and subject to change. Do you understand the scientific method of starting with a null hypothesis? If yes, state your hypothesis please.

That’s fine. Thanks engaging. There is no obligation to continue the conversation. This is a time of heightened anxiety. We should use evidence not emotion to guide policy. A goal of mine is to improve ppls critical thinking skills to make rationale decisions

In survival situations it’s only rational to err on the side of precaution. Waiting for data can be like getting in to a car crash and trying to fashion the seatbelt. You don’t need data (though it is available http://masks4all.co ). You just need to know if someone sneezed ..

Disagree. Treatments have potential benefits & harms. The Cognitive bias is to over emphasize benefit and minimize harms. The data does not provide a clear answer (agree?). You are presupposing benefit while I’m saying I don’t know.

Preponderance of evidence of benefit (stopping asymptomatic/presymptomatic spread) plus removing stigma thus allowing sick people to wear, plus alleged risks are all either speculative or unlikely (false security, almost never supported in lit). Yep, contrarianism for no reason.

Humility is good, being contrarian for no reason is not. Preponderance of evidence is so strong that even CDC/WHO that almost never shift like this have. But let me not interrupt the hashtag. #humility

I’m not being contrarian? The scientific method starts with a null hypothesis. Those claiming net benefit of mask wearing by asymptomatic ppl in public to prevent clinical disease have to demonstrate their claim with evidence. That burden hasn’t been met and I accept the null

Even if I was providing a contrarian position I have good reason. I want people to get the best advice, based on the best evidence. Two reasonable people can look at the same data and come to different conclusions (agree?)
