We need experts.
But we also need to use our brain.
Even when trying to use my brain, I have troubles understanding how droplets can distinguish the direction of passing through a face mask, i.e., how my face mask can help protect others from my droplets, but how it cannot protect me from other people's droplets.
Well, I do understand that if the holes are too large, it will not be a 100% protection, but I do not really understand how the direction would matter.
That said, preventing a run on masks is important if you don't have enough, because some people need masks more urgently than others. I am convinved that in order to prevent a run on masks, you cannot just tell people the truth, but you need to lie to them, because many (or most) people will still get a mask if they know it is actually somewhat helpful.

Masks don't necessarily completely stop all the droplets, but the ones they let through are slowed down, which means they fall to earth at a much shorter distance than unimpeded ones. Incoming droplets that doesn't matter all that much - they only need to go a few millimeters to reach your face. Outgoing droplets, though, need to go six feet before they hit someone if you're practicing proper distancing.
