I made a B in POLSCI101 55 years ago. One of things I learned in the course was Bismarck’s definition of politics: the art of the possible. Another thing I learned was that what is called “political science” has essentially no connection to or use for the scientific method. As Bismarck noted, politics is an art, and the study of it is no more a part of science than is the study of music or any other art.
That’s not to say that politicians don’t claim to be basing their action on science. Marxism, for instance, claims to be “scientific socialism.” The history of the 20th Century shows what happened every time the marxist hypothesis was tested against Reality.
“Scientific” Covidicism has had its test against Reality, and its Narrative hasn’t done well. Indeed, it’s done so poorly, that even the blue states are beginning to return to the Real World.
The science hasn’t change. A bit of pseudoscience has failed, and it’s an election year. The art of politics says that the way to survive an election is to stay on voters’ good side. And the voters have had enough of covid restrictions that didn’t work or were actually harmful.
