It's a fair question. One could argue that it doesn't really matter. We often take comfort from a large body of evidence supporting a course of action. Let's assume we don't have that in this case. Could we not invert the question? I.e. is there evidence that wearing (or the mandate) masks increases the spread of the virus? Or could we relax our need for evidence and use the precautionary principle? That is to say one may have doubts about what is being said about the virus but to be on the safe side wear the mask anyway.
