I sometimes refer to the COVID-19 pandemic as “the great psychometric test.” We are all being placed under different kinds of strain, and we have the chance to react for better or worse.

One set of tests has concerned masks. There is increasing evidence that masks stem the spread of the virus, yet the U.S. is not embracing mask-wearing. It is the only major nation that has turned masks into a partisan political issue. That is a psychometric test for this country, and we are failing it.

The next test, I think, will be which institutions can succeed at getting Americans to wear their masks. That in turn will be a test of which institutions Americans truly trust — or are at least willing to defer to.

So far it doesn’t seem that our public health authorities are going to take that crown. No systematic data are available, but in my home area of Fairfax County, Va., mask-wearing seemed much more common a few weeks ago than it is today. Where I go and what I see is obviously not a scientific sample, but of course what I should be seeing is mask-wearing rising visibly and sharply, approaching near-universality. That is not the case. And by no means is it only Trump supporters who are failing to respect appropriate mask norms - Fairfax County went heavily for Hillary Clinton over Donald Trump in 2016.

If public health authorities have not been able to encourage mask-wearing among the general public, are there institutions that have succeeded in doing so on their own patch? One example might come soon from reopening universities. I suspect that mask-wearing will be a sustainable norm in any classroom that requires it, if only because the professor can observe norm violators and ask them to leave. The professors will have an interest in enforcing this policy, and most academics lean to the left, largely inoculating them from the anti-mask rhetoric and behavior of President Trump.

Still, I doubt that it will be possible to enforce the norm of mask-wearing in dorms and other common spaces. After all, universities have not succeeded in stamping out drug and alcohol abuse on campus, or for that matter enforcing class attendance or homework requirements.

Another hope on the mask-wearing front is American business and the American workplace. I am struck by how every package delivery person I have seen - and these days that is many - is wearing some kind of mask, even though they are out on the road, away from their bosses, and not usually coming into much close contact with their package-receiving customers.

The other workers I see, such as waiters or retail clerks, also are wearing their masks pretty much universally, even during my recent West Virginia and Ohio road trip, a region where otherwise mask-wearing was very low.

Of course, compelling workers to wear masks is one thing; asking customers to do so is quite another. AMC movie theaters will be reopening in mid-July, and they now have decided all customers will have to wear masks. That will perhaps be the acid test for how much Americans respect businesses as a source of authority, because movie theaters are relatively dark and ushers (to the extent they still exist) may be reluctant to interrupt movies to enforce mask-wearing.

As a nation, we desperately need to realize that we are failing this test.
