If anything, this simply underscores GP's point. Getting hysterical when you lack information is a total failure of critical thinking, so to the extent that liberal arts educators did so, we should be skeptical of their ability to think critically.
There's more of an argument here regarding lockdowns going on longer than they needed to, but as much as people want to blame "the experts", most of that was bottom-up from voters. To cite one example, despite how many times I've heard to the contrary, the CDC never, at any point, recommended school closures: that was pure grassroots demand from parents.
Classical liberal arts are wonderful, and have been a great benefit to all of humanity. But sadly many academics no longer live up to those ideals in thought, word, and deed. Instead they're more focused on indoctrination and political advocacy then a search for higher truth. If they want to restore public trust in liberal arts education then they need to start by reforming themselves. Otherwise no one will take them seriously, and many taxpayers will oppose public funding.
The If Books Could Kill podcast just came out with an episode last week about how the phrase "lockdown and mandate policies [have] zero scientific basis" is almost technically true but is certainly incredibly misleading. The short version is that it would be incredibly difficult to ethically test many healthcare policies to the point that they have scientific support in the way we usually think of having evidence... but we can look at the preponderance of evidence we do have and understand that masks help block germs and viruses, staying home from work or school means I won't transmit contagious diseases to my colleagues, etc
