The Masks Supermyth is Bust with Experimental Research

Where, exactly, is the experimental research to test the hypothesis that masks do not help reduce the spread of Covid19?

Yet further published experimental research @brianjford to support the hypothesis that facemasks do reduce the spread of #Covid19. Where is the experimental research revealing that they do not? https://t.co/ol7EIbbzCz

Brian J Ford kindly shares a journal article looking at how effective masks are against Covid19

@trishgreenhalgh Folk don't cough straight into a petri dish in shops though. As nutrition advice based on what happens in a petri dish may have little to do with inside a person. They wrote
"We do not know whether masks shorten the travel distance of droplets during coughing."

Well it may not be deliberate. But, following your observation. let's ask a telling question:

"If Covid19 had worst mortality impact by far on young, rich and white people (rather than the old, the poor and black/minority ethnic populations) would the policy making be different? https://t.co/nlg7IS3jwa
