We have confounded evidence of a weak effect. If I had to bet (and we all have had to), I'd say they do have a small benefit on a population scale. But if more evidence showed up saying they didn't, I would be completely unsurprised.

I think it's worthwhile to have doubt and be skeptical.

I'll note that, at the beginning of the pandemic, I was saying that masks may or may not work, but they should still be recommended at a time that the CDC was implying that they might even be harmful.

This is all completely consistent with what I originally said: "To be honest, we still don't really know if masks work. They look like they probably do something, but the evidence is weak and the effect size small."
