Reply to comment by die_kuestenwache in What are the best alternatives to a double-blind RCT if blinding is impossible: example you cannot have a double-blind RCT to test the effectiveness of masks against covid. What is the best way to test if masks, as worn in real life, are effective? by DenebianSlimeMolds
the claim is made that unless you are testing masks in real life, for example on kids going to school and playing all day, sometimes wearing masks and sometimes not, you really aren't testing masks in any meaningful way that matters in terms of how kids will use them.
