NEW HAVEN – I have been in the forecasting business for more than 50 years. Over that period, I have heard the constant refrain that the world is in the midst of “unprecedented changes.” This popular trope frequently resulted in equally hyperbolic corollaries: breathless claims that we have never faced greater risks or such an uncertain future, that forecasting has never been harder. Repeat it enough, and it starts to become believable.
