Addressing threats like Covid: why we will tend to over-react and how we can do better

A number of behavioral economic insights suggest we will tend to overreact, individually and collectively, to a new, serious, but low probability health threat, like Covid 19. To respond more effectively to such threats, we should recognize why we will tend to overreact and prepare in advance not to do so. We also should recognize the usefulness in giving lower level governments, non-profits, and less formal communities some ability to respond, rather than presuming we should address a significant threat like Covid using the highest level of government.
