For eighteen months, I have been infinitely puzzled that most responses to the Wuhan Plague have been irrational. Lack of rationality dominates the discourse and actions of the majority, from individuals to governments. This irrationality has innumerable manifestations, the most obvious being belief in plain fictions, recently the made-up threat of the new “Delta variant,” no doubt not the last in a very long list of fairy tales. The irrationality shows itself in many other ways, both secular ones such as the total rejection of cost-benefit analysis, and quasi-religious ones such as belief in strange new gods, saints, and rituals. I have racked my head trying to understand this very strange phenomenon, and made no progress.
