Fauci said the 6ft rule was made up and not based on science.
Likewise first he said don’t wear masks. Then he said do wear masks.
The trouble is, made up stuff with no basis in science doesn’t prevent deaths from Covid.
That's actually not really accurate.
Prior to the development of vaccines, the only three things that were proven to lower disease morbidity rates were distancing, masking, and ventilation. The fact that studies were not done to establish a dose : response relationship (i.e.) how much of each caused how much benefit, and the establishment of thresholds as opposed to gradients, does not make them "unscientific" or "unsupported by fact". Given the cost, time constraints, scale and chaos, those kinds of studies were never going to be possible. In other words, we know that distancing, masking, and ventilation all reduce disease transmission. We just never had linear data from say 6" up to 100 ft of distance to know how much benefit is gained or lost be each additional foot. No was it going to be possible to generate such data on any sort of widespread basis because of human behavior.
With respect to masking, during the initial months of the pandemic, masks of every sort were in short supply and governments/hospitals, etc. were forced to triage mask availability. But as the pandemic wore on and supplies became plentiful we were able to measure the effectiveness of various masking scenarios from cloth masks up to N95. There is a reason why masks are used in hospitals and during surgery. They do work when used correctly.
With respect to ventilation, building owners were reluctant to spend the money to improve ventilation, and the time frame was not practical. The aerosol theory that replaced the droplet theory of transmission actually favors greater, not lesser, distancing. American litigiousness forces all safety policies to err on the side of excess. Establishing default measures from previous experiences is the most logical starting point. The goal of buying time until vaccination became widespread was generally successful.
Science has two components. Inductive reasoning uses specific trials or experiments to develop theories. Deductive uses established principles to guide future behavior. The initial COVID restrictions were an example of deductive reasoning that was validated by lower rates of disease morbidity compared to absence of restrictions. That process was decidedly scientific. And we have plenty of comparisons between different states, schools, and jurisdictions that had different mask and distancing mandates.
