> No mask mandate has ever reduced the R number or growth trajectory anywhere in the world. And no study has ever confirmed beyond reasonable doubt that cloth and surgical masks work in any way against covid. KN95 perhaps, N95 definitely, but that's fairly obvious since it actually fits on your face and has a particle filter.

Could you confirm this with a study ? This seems ridiculous

Can you tell the difference between places that had mask mandates and places that did not?

I don't get what the point of that quiz is. All of the example countries in it instituted their mask mandates between the first and second wave. None of them did not?

This guy seems to exist to create charts that a) show vaccination does nothing to stop Omnicron, which seems to be all recent charts or b) that demographically similar states/countries that are neighbors have virtually identical results when one has a mask mandate and the other doesn't: https://twitter.com/ianmsc/

Given how infectious Omnicron is, these mask mandates are nothing more than talismans.

He's doesn't seem very credible though. For example, there's a lot of very obvious reasons which could help explain this[1].
