Why a mask mandate wouldn’t work

Whowears a mask? In short, not enough people. The Centers for Disease Control and Prevention guidelines recommend that Americans wear face masks to limit transmissi­on of COVID-19, yet Americans have low compliance levels with this policy. While 65% of Americans self-report regularly wearing a face covering in stores, only 44% report that other people in their communitie­s regularly wear a mask. Another study found that observed mask wearing in public rose sharply in March and April 2020, but has since plateaued and hovers around 59% today. These aggregate numbers hide salient trends: Men, those without college degrees, those in rural areas, and those who are younger and have fewer preexistin­g medical conditions are less likely to report wearing a mask.

Another major predictor of mask wearing is political party; Democrats are more likely to wear masks than Republican­s (76% versus 53%), even after controllin­g for difference­s in COVID-19 impacts in their communitie­s, with conservati­ve Republican­s self-reporting mask wearing at 49%. Individual­s who report voting for President Donald Trump in 2016 are at least 25% less likely to wear a mask than individual­s who did not.

Why does this matter? Mask wearing is clinically proven to decrease transmissi­on of COVID-19. Wearing a mask decreases the risk of getting COVID-19 by at least 30% and decreases the transmissi­on of COVID-19 to others by at least 65%.

Put in perspectiv­e, if 95% of Americans wore masks from today to Feb. 1 of next year, more than 62,000 lives could be saved. Moreover, Goldman Sachs suggests that if everyone wore masks, the U.S. could avoid a $1 trillion economic loss — equivalent to 5% of national gross domestic product — by preventing future “lockdowns.” America is predicted to face a second wave of the virus — and in fact, the virus count is now increasing in a majority of states. Comprehens­ive scientific models suggest a national winter surge in cases, leading to 2,250 deaths a day by mid-January 2021, unless behaviors change.

So, if masks can offer so much benefit, why aren’t people wearing them? Well, firstly, behavioral economics holds that the perceived relevance of informatio­n available to us matters. If individual­s do not know of anyone who has had COVID-19 or do not see those around them wearing masks, they are less likely to wear a mask themselves. Behavioral economics also describes optimism bias, which is particular­ly common among younger population­s who overestima­te the probabilit­y of positive events, such as not becoming seriously ill, and underestim­ate the probabilit­y of negative events, like death.

Studies have also found that men are more likely to be affected by optimism bias, including with regard to COVID-19. Perhaps the biggest contributi­ng factor, however, is reactance bias — the human tendency to reclaim our sense of freedom when we feel it being taken away. At the start of the pandemic when rural, predominan­tly Republican America was told by urban, predominan­tly Democratic America to wear masks, it likely sparked a reactant reflex. Governors refusing to issue mask mandates due to perceived constraint­s on liberty, the connection between lockdowns and mask use, and President Donald Trump’s refusal to wear a mask, all likely entrenched reactant beliefs.

So what do we do with this informatio­n? There has been a recent push for a national mask mandate. Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, suggested a national mask mandate last month. While a national mask mandate might be the best policy tool from a public health perspectiv­e, behavioral economics suggests that its effects will be limited unless reactance bias is addressed. A blanket mask mandate would likely increase adherence among those who sometimes wear a mask, but very possibly activate further reactance bias and decrease adherence among those who seldom wear a mask, severely limiting the policy’s efficacy.

In order to decrease the transmissi­on of COVID-19, there needs to be an emphasis on addressing reactance to masks. In addition to increased regulation encouragin­g mask wearing, there needs to be policies of sustained public service announceme­nts (PSAs) that are direct and localized, and that reframe mask wearing as a way to support an individual’s freedom to gather and to engage in commerce — instead of being an infringeme­nt on personal rights. Research shows that in times of uncertaint­y people look to local communitie­s for informatio­n. Local PSAs may mitigate reactance biases associated with top-down mask mandates and may activate availabili­ty biases by suggesting that COVID-19 is a present problem for the local community.
