Except that there is research showing some impact on transmission from the application of mask wearing mandates. It’s not completely cut and dried, but supported by research evidence. You, and others, in your interpretations of case graphs, consistently fail to consider the “what if” of not having a mask mandate, and also the possibility that an intervention that is less than perfect may still be of value. Likewise, I’m always intrigued by the insistence of some that nothing less than gold standard research (i.e. double blinded RCT) can be good enough to use for a policy intervention.
Given the low impact nature of this non medical intervention, and a reasonable policy of permitting exemptions to those who genuinely can’t tolerate them, I am always surprised at quite how much animosity mask wearing requirements cause.

@nedchester, I’ll be delighted when I can junk mine and go back to being unmasked. But, of the various interventions in play, mask wearing is the least intrusive.
