Yes. They all have problems. Small sample sizes, or non randomized groups, not double blind, etc. But, it’s all we have. The preponderance of data (imperfect as it may be) suggests that a public mask policy is prudent. Given the extremely low burden of wearing a mask, and the weight of the evidence in its favor, I really can’t understand anti maskers. Most of my friends are anti mask, and I’ve listened and tried to understand, but I always come away thinking they’re simply uninformed. Most of them get their information from sources that border on being conspiracy theorists.
