David Zweig's new book An Abundance of Caution (MIT Press) is an account of the decision-making process behind the extended closures of public schools during the pandemic. In fascinating and meticulously reported detail, Zweig shows how some of the most trusted members of society—from Pulitzer Prize-winning journalists to eminent health officials—repeatedly made fundamental errors in their assessment and presentation of evidence. By fall 2020, many students in Europe were already back in classrooms—and so were their peers in private schools in America and in public schools across mostly "red" states and districts. Yet millions of other children across the U.S. remained under extended school closures. Whatever inequities that existed among American children before the pandemic, the selective school closures exacerbated them, disproportionately affecting the underprivileged. Deep mental, physical, and academic harms—among them, depression, anxiety, abuse, obesity, plummeting test scores, and rising drop-out rates—were endured for no discernible benefit. The story of American schools during the pandemic serves as a prism through which to approach fundamental questions about why and how individuals, bureaucracies, governments, and societies act as they do in times of crisis and uncertainty. Ultimately, this book is not about COVID; it's about being ill-equipped to make decisions under duress. David Zweig is a writer, lecturer, and journalist.
