When my colleague asked for scientific evidence to back this denial, the poster directed her to an article by Denis Rancourt, entitled “Masks Don’t Work.” And, indeed, Rancourt’s paper cited eight peer-reviewed essays, all from reputable journals. But when she actually clicked on the links provided, she found something very curious. None of the studies cited concluded what Rancourt says they did. For example, six of the eight studies measured the effectiveness of N95 respirators compared to surgical masks—not, as Rancourt implied, the effectiveness of wearing a mask vs. not wearing a mask.
A full debunking of Rancourt’s entire article would take more space and time than I have here (I have published one here), but at this point one would be justified in concluding that his entire argument is bunk.
