I'm sure we're all well aware of the times analytic & statistical 'modelling' has thrown frightening figures at us for infections, serious illness, deaths, a fractured economy, no food on the shelves etc etc.
Quite possibly 'Worst Case Scenario' has played a part in this, which is probably better than speculating on a Best Case Scenario and being hit in the goolies by people moaning they weren't warned.
Just my opinion of course
