Suspending my disbelief here for a second, is there any evidence that double-masking is meaningfully more effective than single-masking?

Have seen a lot of people ask in seeming good faith what the harm is. To me it’s pretty clear: asking or telling people to do something that is some measure of inconvenient for no good reason is bad on it’s face and fosters resentment. That’s before we get into mask scolds etc.

One of the clearest lessons through the pandemic has been that people in general and Americans in particular don’t like to be told something is helpful or important when it isn’t either. Doing so undermines trust (for good reason!) in the institutions doing the telling.

So the major downside to telling people to double mask is that they’ll think medical experts are even more full of shit than they already think. In the middle of a pandemic, this seems like a bad thing.

So, do we have any evidence that the benefits of 2x masking outweighs that?
