First post of my GA career for those noticing my handshake status. Question: I see peer reviewed and published evidence that masks do NOT work, but has anyone seen the same saying that they do work? I want to be able to say to my boss that there is no such evidence--I have not found any. You?
Edit: Thanks to everyone for comments and links. Looks like this topic has been discussed in the past (like so many items on this site). I appreciate the input and your patience. Being new, this was good to see.
I read many, and the most positive about masks were still in the "sometimes in certain circumstances some masks look like they might have helped reduce transmission by up to 2%." Which is pretty poor and generally goes with the old saying "negative results don't get published." And if you don't get published you don't get funded. Many studies are busy work for grad students too.
