Relevant excerpts
The top scientific journal Nature Medicine published a study on Oct. 23 with an astounding claim: By simply wearing masks at higher rates, Ameri-cans could prevent as many as 130,000 Covid-19 fatalities by the end of February 2021. Produced by the University of Washington’s Institute for Health Metrics Evaluat ion, or IHME, the study garnered immediate acclaim..............
Unfortunately, the IHME modelers’ findings contained an error that even minimal scrutiny should have caught. The projected number of lives saved, and the implied case for a mask mandate, are based on a faulty statistic. Using a months-old survey, IHME modelers assumed erroneously that the U.S. mask-adoption rate stood at only 49% as of late September, and therefore had plenty of room to increase to “universal adoption,” defined as 95%, or to a more plausible 85%. According to more recent survey findings, however, America’s mask-adoption rate has hovered around 80% since the summer.
Which also means the recent spikes came EVEN THOUGH mask wearing has been near its highest practical level since the summer.
Any serious scientist understands that to discuss the Covid merely by doing a mask-on/mask-off analysis is just plain silly.
The same with taking the POV that society should lockdown or go with herd immunity.
Social distancing in concert with wearing a mask has proven to be the essential key to reducing/slowing the outbreak of the virus.
The better term (since choosing the right term seems to have real political consequences) would be
dial back, as in dial back access to enclosed areas that reduce opportunities to social distance (like indoor bars, restaurants, gyms).
So, for example, the NJ governor is choosing to
dial back the hours a bar can be open, not closing them, but having them close earlier.
Still, you can't fix stupid---like the popular Jersey Shore bar that refused to take social distancing seriously, which led to 9 of its employees to test positive for the virus, and led to closing the establishment for an indefinite period. Or the stupidity that is college football, which allowed its fans to storm a field after winning a meaningless game. That has already led to more Covid positives at Notre Dame. And now, those same idiots will want to go home for Thanksgiving. Brilliant!
So, it's human behavior and not wanting to respect or understand the science that is causing much of our problems here in the USA.
And much of that lack of respect for both science and other humans has its origins on the right side of the political spectrum.
Like I said. You can't fix stupid.
To come on here and play games with "look what I found on masks" serves no purpose.
But it does show the limitations of one who would do so.
