Social influencing is more important. Who is "popular" in Kansas? I'm not a native Kansasian...who could spread the word that they are using a mask for the duration of THIS pandemic. (there will be another!)

The phrase, "Studies show ..." seems to me to be a more significant human invention, to motivate immediate behavior, than the actual technical studies themselves.

Just slap "Studies show" on the front of any believable collection of words which could be reasonably determined to be "common sense", and watch the behaviors trend.
