The new virus is a great confirmation of @nntaleb distinction btw phenomena where we can use the knowledge derived from Mediocristan and the phenomena that belong to Extremistan and where Mediocristan knowledge is useless.
Somebody pointed out that the number of deaths from corona is (so far) less than the deaths from an ordinary influenza. But the latter is Mediocristan, we know its distribution, high values. The corona is unknown. We do not know its extreme values.
