There's some evidence, and countries w/ mask culture seem to be doing better. It also has a psychological value of reminding yourself not to touch your face and reminding others that to keep distance. So, that could also be part of the reason it works, could be some placebo effects that add to the safety, but the fact is masks don't really protect the wearer because apparently stuff can come in through sides/and such but it protects others if you cough or sneeze, or just breath out droplets. It's a combined effect that only works if it's got at least 80% compliance, preferably 100% should be required. Why take the risk of killing someone if the wearing a mask could alleviate it? Is wearing a mask such a horrible thing?
