Multiple sources in USA claimed masks were not needed for people without the disease. Heavily implying it was useless.

I of course knew that was BS from the get-go. But nonetheless they did say it.

Yes, we used to think non-N95 masks (let alone cotton masks) wouldn't help, and then when we got more data to the contrary, we had to update this belief. That's unfortunate, but normal.

Wait, people change their beliefs in response to new data? That's unpossible!
