How do masks not meet the scientific standard of efficacy? I understand you're not making an anti-mask argument, but I'm just genuinely curious to understand wh

  Not OP, but the primary studies saying masks are effective are basically experiments of function, such as, does a mask block particles more than not wearing a mask? However, studies on their effectiveness in the past have never found actual protection from diseases. For example if every one covers their mouth were they sneeze anyways, then what is a mask really doing? Do people touch their face more often with masks, reuse masks, and actually bring more particles to their face? Diseases are not all airborn and live on surfaces, so is all this interaction with your face to large untrained groups actually increasing the risks? The best we have now is comparing groups of people or states with different policies, which is also not proving masks are effective, but could that cause be due to people still following rules even though the policy isn’t forced or some other unknown reason such as hers immunity being reached, etc.
