How to make everyone start wearing masks
Nations must apply three basic principles from behavioural science: make it easy, understood and expected
Hong Kong has so far reported a grand total of four coronavirus related deaths, while New York City has reported over 20,000. Here’s another striking comparison: Close to 99 per cent of Hong Kong residents have been wearing masks, to prevent the wearer from spreading the virus, since early February. According to a mid-April Gallup poll, only a third of Americans say they always wear a mask or cloth face covering outside the home. Another third of us sometimes wear a mask in public, and a third never do.
Universal face mask adoption isn’t the only difference between Hong Kong and the United States, and it’s not a substitute for physical-distancing, hand-washing and other preventive practices. But masks — even just a scarf, bandanna or an old Tshirt and two rubber bands — are widely viewed as critical to stopping the transmission of the novel coronavirus.
Nevertheless, face-mask compliance has been uneven. This is especially worrisome in closed, crowded spaces like subways and buses, grocery stores and offices where it’s not easy to maintain a distance of six feet from other people and avoid spontaneous coughs and sneezes.
The most obvious path to universal masking is to pass laws and punish infractions. But enforcing legal edicts to wear masks in public can be difficult and costly, and amid widespread ambivalence can lead to backlash and even violence. So edicts are not a complete solution.
Complementary approach
As experts in public health and human behaviour, we propose a complementary approach: Make wearing a mask easy, understood and expected.
Where can you get face masks? You can search for them online, you can now buy them in drugstores and yes, you can make them yourself. But none of these options are effortless.
Imagine if every city and town in this country had an Adrian Cheng, the real estate developer in Hong Kong who had a manufacturing line set up in one of his empty properties and made the masks available free to the needy in vending machines devised specifically for the purpose. Not long after, the Hong Kong government set up a website where any household can register to have reusable masks delivered free. Or consider Utah, where residents can likewise register online and receive a free fabric face mask by mail. The cheaper and more ubiquitous face masks are, the easier it will be for Americans to get our hands on them, and the more likely we’ll do so and wear them.
Not long ago, the Centers for Disease Control and Prevention (CDC) and the surgeon general in the US were lecturing the public on why they wear face masks. That recommendation flipped once it became clear that people infected with the coronavirus can spread it before they know they have it and, therefore, everyone should wear a mask to reduce the chances of infecting others. Since it’s hard for people to update their beliefs once a message has been received, it’s no surprise that misinformation and outdated news continue to ricochet in the echo chambers of social media.
Therefore, it can be helpful to supply people with a rationale to change their behaviour without looking like a hypocrite. For example, officials can emphasise that at the start of this crisis, nobody could have known how important it is to wear a mask when you have no symptoms, and that day by day, new scientific evidence is demonstrating the efficacy of masks in the fight against the coronavirus.
According to a recent Qualtrics study, a majority of surveyed now say they won’t return to the office unless their company makes wearing face masks mandatory. And in just one week in April, the percentage of Americans who said they wore a mask outside the home increased by more than half.
Norms are also established by high-status role models. Celebrities and professional athletes can do their part by posting photos about wearing face masks in public.
Role models
Norms are also established by highstatus role models. Celebrities and professional athletes can do their part by posting photos about wearing face masks in public. And to counter the politicised nature of the issue, let’s all applaud mask-wearing leaders on both the right and the left. Hurrah for Melania Trump posting a photo of herself in a mask, and hurrah, too, for Nancy Pelosi wearing a scarf on the House floor.
The story of face masks is still being written. We may lack the wisdom Hong Kong earned weathering prior epidemics, but it’s not too late to apply three basic principles from behavioural science: make it easy, understood and expected, and we’ll soon see face masks everywhere, saving lives.
