In operational forecasting, the goal of probabilistic forecasting may be unattainable due to model imperfection. Consequently, the resulting probabilistic forecasts will be defective. Considering macroeconomic forecasts for both the UK and the US, the types of defects that one can have are discussed. Both theoretical and empirical results are presented, which include ways to remedy these defects. One can have either pessimism or over-confidence in some way. Is it high time we realised that calibration is a mirage and should use alternative approaches to assess probabilistic forecasts?
