How did they account for people "doing something different" when wearing a mask? I.e. did they do a double-blind experiment where people wore masks that had intentional holes in them? So we can know that wearing a mask is the thing to do vs whatever it is that wearing a mask caused that person to do. I guess I'm asking or saying that this might have been some sort of "correlation is not causation" kind of thing?

I get that for whatever reason folks like yourself don't want to believe it, but trust me, masks work. Just ask anyone who works in asbestos abatement or BSL-2+ facilities.
