If you add up all the numbers on those two lines, you find that the mask mandates made zero difference. The cumulative rate of infection over the course of the pandemic was about 24 percent in the mandate states as well as in the non-mandate states. Their cumulative rates of Covid mortality were virtually identical, too (in fact, there were slightly more deaths per capita in the states with mask mandates).
If this hasn’t persuaded you to take off your mask, you can find lots more reasons in a book by Ian Miller, the data analyst who created the graph for City Journal. Miller, who has tracked pandemic trends for the Brownstone Institute, has assembled the damning evidence in Unmasked: The Global Failure of COVID Mask Mandates. The book documents how mask mandates were implemented without scientific justification, how they failed around the world, and how public officials and journalists have kept making fools of themselves by pretending otherwise.
And there you have it.
