“Second, it carries an extreme impact. Third, in spite of its outlier status, human nature makes us concoct explanations for its occurrence after the fact, making it explainable and predictable.”
In the case of the coronavirus, no one predicted a disease would cause more than 60 million people in China to be locked down during the Lunar New Year, the country’s busiest travel period, paralyzing the Chinese economy.
The outbreak, and its resulting fallout, caused Wall Street economists to slash their growth estimates for China, the second-largest economy on the planet. J.P. Morgan said Chinese economic growth would temporarily slow from its current growth rate of 6 percent to just 1 percent. In its adverse scenario, which includes the contagion not peaking until April, J.P. Morgan warned the Chinese economy could contract by 3.9 percentage points.
