I'm not convinced by that narrative. I think there is still limited proof that masks make any noticeable difference. But the public demanded mask mandates (unlike things like vaccines this is very noticeable so for many people it gives them a peace of mind that something is being done), so the officials delivered. But to save face, they invented a story how they always knew masks work great, but didn't want people to do a run on masks.
This. The officials dig up a scientific story that justifies going along what their electorate among the public demands, then they back up with a cohort of white coats on TV.
Simon says we don’t have masks, so science finds masks useless.
Simon says wear masks, so science finds masks important.
It says “We’ll lie to your face just for the lols”. Also, my government inoculated AIDS to 10,000 patients in 1985 and took 6 years to admit it. This science, is not science. It’s very diligently pruned for political profit, and it works.
So “I’ll take my vaccine in 6 years” is a reasonable answer in a former communist state.
