Just when the forces of rationality had seemingly established a beachhead in the public health domain, they’re back on defense again, as the CDC declares vaccinated and unvaccinated people should wear masks indoors in areas of the country experiencing high transmission, and every schoolchild should be condemned to wear a mask all day long.

The moves, which come in response to surging case counts, seem to demonstrate an impulse that animates many questionable government policies: “We have to do something,” regardless of whether that something can be reasonably expected to have a material impact on the problem at hand.

Ample Reason to Doubt Masks’ Value

Most public and media discussion of mask policy reflects a foundational assumption that may well be false—namely, that widespread, all-purpose mask-wearing has had any meaningful impact on slowing the spread.

Intuition tells us covering our faces must be worthwhile. After all, if the virus is emitted from our noses and mouths, covering those openings has to make a big difference, right?

That gut feeling misleads us, though, because we tend to only think of the virus in terms of visible, tangible droplets masks can absorb. Indeed, the initial scientific consensus held that COVID-19 was exclusively transmitted by droplets, prompting the emphasis on distancing six feet from each other—room enough for gravity to pull those droplets out of the air.

That exclusive-droplet-transmission consensus proved wrong. We now know COVID-19 is spread to a great extent via aerosols—a term that describes particles so small they can easily float along in the air, traveling well beyond six feet.

Even that description fails to convey how unfathomably small COVID-19 viral particles actually are—and why masks are a mismatch.

How small are they? As little as 20 nanometers.That means the “material gaps in blue surgical masks are up to 1,000 times” as large as a Covid-19 viral particle,according to Colin Axon, who has advised the UK’s Scientific Advisory Group for Emergencies (SAGE).

Gaps in typical cloth masks can be 5,000 times the size…to say nothing of all that air that’s merely redirected past masks’ edges when we exhale.

A Tale of Two Countries

While the comparative virus and mask dimensions give one pause, they merely form the basis of a reasonable hypothesis that masks do little to inhibit the mobility of viral particles.

What really counts is observed results in the real world—and what we’ve observed should sow creeping doubt in even the most fervent masking advocate.

“All around the world you can look at mask mandates and superimpose on infection rates, you cannot see that mask mandates made any effect whatsoever,” said Axon to The Telegraph.

While there are many illustrations of that conclusion, perhaps none is more vivid than a comparison of Sweden—which, as a society, never went all-in on masking—and Germany, whose government in January went beyond merely requiring “face coverings” and mandated the use of medical-grade masks.

Despite Sweden’s sharply lower use of masks—and a much more relaxed approach in general—the country’s 12-month experience is essentially indistinguishable from what’s observed in Germany. Rather, one sees a force of nature taking its seasonal course.

“The best thing you can say about any mask is that any positive effect they do have is too small to be measured,” said Axon, a Brunel University (London) lecturer in engineering who notes that “when the particle enters another body, it returns to a biomedical issue, but the mask debate is about the particle journey,” where his knowledge applies.

Meanwhile, the United Kingdom’s experience delivers a one-two punch. First, there’s no indication the imposition of mask mandates slowed transmission, which marched along in seasonal fashion. Second, the recent reopening of the country and lifting of mask mandates amusingly coincided with the beginning of a steep reversal of the summer surge in cases.

Masks May Be Counterproductive

As with so many ill-considered government programs—such as the war on terror or the war on drugs—mask mandates may actually serve to amplify the peril they’re meant to minimize.

That’s because unwarranted confidence in masks can give wearers a false sense of security and lead them to neglect risk management steps that are actually worthwhile.

That’s the view of Harvard Medical School epidemiologist and biostatistician Martin Kulldorff. “Naively fooled to think that masks would protect them, some older high-risk people did not socially distance properly, and some died from #COVID19 because of it,” he said in a May 2021 tweet.

Kulldorff’s tweet was short-lived. Twitter’s thought police, whose Orwellian curation of Covid content centers on a presumption of CDC infallibility, promptly blocked the tweet and locked the Harvard scholar out of his account.

Masks: The Last Taboo in Covid Discourse?

Today, relatively few scholars and prominent health professionals join Kulldorff and Axon in publicly questioning the value of widespread masking.

However, if the history of the controversy over COVID-19’s origin is any indication, there may be many others who harbor doubts, but, fearing the social and professional repercussions of speaking their minds, are waiting until it’s safer to do so.

In May of this year, nineteen scientists published a letter in the journal Science demanding an investigation that would examine the possibility the virus escaped from China’s Wuhan Institute of Virology. One of the scientists said she and others didn’t speak up last year because they were apprehensive about being associated with Trump and his supporters.

There’s an obvious parallel to masks, which have been embraced by millions of Americans not only for their perceived health value, but as a means of signaling their virtue and membership in the liberal and/or anti-Trump tribe.

That emotional and political attachment to masks—which infects the media as well as individual citizens—represents a powerful barrier to an intellectually honest evaluation of their effectiveness. The sooner that barrier begins to crumble, the better off we’ll all be.
