I'm not saying that masks don't work. But whether they are effective at reducing transmission and, if so, in what measure are open questions. The literature is at this point inconclusive[1]. Even the latest Lancet paper on masks and distancing attracted some criticism[2].

Of course,I agree that absence of evidence is not evidence of absence. But, as the BMJ post I quoted earlier says, instead of just saying "wear a mask", the best idea would also promote trials to verify their effectiveness (like the Danish trial). It's done all the time for drugs, why not masks?
