Severe Damage to Beliefs Lasting a Lifetime: covid-19

According to a new study  “Scarring Body and Mind: The Long-Term Belief-Scarring
Effects of COVID-19
” the largest economic cost of the COVID-19 pandemic could arise from changes in behavior long after the immediate health crisis is resolved. A potential source of such a long-lived change is scarring of beliefs, a persistent change in the perceived probability of an extreme, negative shock in the future. Even if a vaccine cures everyone in a year, the COVID-19 crisis will leave its mark on the US economy for many years to come because of the mass revision of beliefs that lasts through a lifetime. Even before the COVID-19 pandemic, people were aware of the disruptive impacts that a pandemic could theoretically have on their lives and the economy. But the tangible, persistent and severe harms associated with an actual pandemic change beliefs about the probability of another similar shock in ways that abstract knowledge cannot.
