I don't disagree with any of that. Indeed, there are many policies and behaviors that probably fall into the "better safe than sorry" category--given how much noise and uncertainty there is in the data--although even possibly reasonable people will vehemently disagree about what precise policies/behaviors that applies to. (As you see from voting patterns and discussions here.) And, yes, I also agree that face coverings under at least many circumstances fall into that category.

At the same time, there are different tradeoffs because different people (and governments) are approaching risks and rewards differently even if the facts were known with high certainty.
