the problem with having 10,000 shamans doing 10,000 rain dances is that, inevitably, a few are going to get lucky and do one right before the rains come

consider this chart from @ianmSC

3 states, same region, same curves. it's clear masks failed in NM, CO

but UT is different

they were not mandating masks and yet got the same curve as the others on the way up, but their local shaman just happened to top tick the mandate.

looked at alone, you could easily be fooled. it looks like it worked.

this is why you need a control group.

when you add that control group, it becomes clear that there is no efficacy signal from masks.

never trust a shaman with an n of 1 in his portfolio.

and even then, be careful. some of them just lie and more than a few of those seem to work at CDC... https://twitter.com/boriquagato/status/1330941552055750657?s=20
