As the world grapples with the Lovecraftian nightmare that is the Covid-19 pandemic, and as the rhythms and rituals of American life are indefinitely disrupted, there are lessons to be learned from the research on uncertainty — including some helpful ways to defang it.
According to a 2014 study in the journal Nature Reviews Neuroscience, uncertainty disrupts many of the…
