>Inaccurate and dangerously wrong conjecture. Research published long before COVID-19 proved the efficacy of masking in blocking particulate matter. Sure, but what wasn't certain was things like: Was covid transmitted in the air by particles (yes)? Was it transmitted via aerosols (no)? Was it transmitted by touch (no)? How many particles are needed to infect someone (unsure)? Do masks protect me or someone else? What type of masks are needed to protect? How many masks do I need to wear? From my exposure, I saw non experts being very emphatic about answers that actually took a long time to get answers to. These emphatic non experts alienated people that continued continued be unsure. In some cases, the experts were emphatic - and then wrong - which further alienated people.
