This reminds me a little bit of the discussion about the effectivity of ppe/face masks, in which direction they are effective, and why in some countries. They are effective, if everyone wears them. It just so happened that there were not enough masks available in the countries which had the most heated discussions about this. You got yelled down for saying so. And then, about two months later, when they were available, wearing them was suddenly mandatory.

Soothing the masses, so they don't seethe...
