Well, the face of the government's response to the pandemic, Fauci, went on 60 minutes and stated flatly that masks didn't work. About a year later he went back on TV and was asked about his earlier comments about masks and he admitted - again, in no uncertain terms - that his previous comments stating that masks didn't work were said specifically to protect mask supplies for health care workers. Seems like he lied to me.
There's 1000 things you're not doing for your health right now because we don't have reason to believe they'll help. Maybe scientists will prove acupuncture cures cancer fifty years from now but anyone who advised against it right now will not become liars.
Or, the information that he had at the time was that masks didn't work. And it turned out that that information was wrong and that when information that it was wrong became available, then we changed the guidance.
I mean seriously, this is how science works and how guidance based on science works. We go wit the best answer we have at the time and continue to search for better answers.
