While Americans still have not adopted mask-wearing as a general norm, were wearing masks more than ever before. Mask-wearing is mandated in California, and in many counties masks are near-universal in public spaces. So I have started wondering: Does wearing a mask change our social behavior and our emotional inclinations? And if mask-wearing does indeed change the fabric of our interactions, is that one reason why the masks are not more popular in the U.S.?

When no one can see our countenances, we may behave differently. One study found that children wearing Halloween masks were more likely to break the rules and take more candy. The anonymity conferred by masks may be making it easier for protesters to knock down so many statues.

And indeed, people have long used masks to achieve a kind of plausible deniability. At carnival festivities around the world people wear masks, and this seems to encourage greater revelry, drunkenness and lewd behavior, traits also associated with masked balls. The mask creates another persona. You can act a little more outrageously, knowing that your town or village, a few days later, will regard that as a different you.
