You describe the science as "mixed", but I think you mean "lacking". Saying the evidence is mixed implies there are some studies showing that mask wearing is effective, and others that it is not. That said, I think that article is expecting far too high of standards. Is there scientific consensus on any public policy measures at the level of rigor the author is asking for? What I find annoying about that article is that he doesn't even hint that it is possible to make a study to get the data we need. How do you plan on doing a randomly controlled study on mask mandates? How do you make a placebo mask mandate?
