Take masking for example, and here is a bomb most people are totally unaware of:
You want the population to wear masks so that the sick people are wearing masks. Masks aren't going to do much to prevent healthy people from getting sick. But they will do a lot to stop sick people from getting others sick.
This truth is almost never communicated though. Why? Because then wearing a mask becomes a "mark of illness" and nobody wants to label themselves as sick or potentially sick. So the solution to this is everyone wears a mask all the time. But you cannot communicate this whole scenario either because most people aren't smart enough to grasp it or not smart enough to understand why they need to wear a mask healthy or sick.
So this is the kind of problem science faces, and frankly I think the best thing to do is exactly what they did: Insinuate that wearing a mask protects you and insist everyone wear a mask.
