"Masks work by stopping air particulates that bear viruses." as in "ya can't fix stupid!"

acsh.org

The CDC's decision to extend the use of masks on airplanes makes little scientific sense. Complete air exchange occurs 20 times an hour; it passes through HEPA filters and is directed downward. A study by the Department of Defense found that the air exchange alone on Boeing 767s and 777s reduced transmission of “viral size” particles by 99%. But, out of an abundance of caution, the public health messaging continues to require masks on all of us because we can not easily or quickly identify asymptomatic transmitters. That is why public policy is informed by science but not based on science – that is the true meaning of “following the science.”
