Obviously, De Finetti’s “later moment” should not be overlooked in applied research. Against the risk that the theoretical paradigms underlying the approximation of reality implicit in a model may prove particularly inadequate in certain situations, it is useful to employ a battery of different models and cross-checks.
This “multi-pronged” approach to modelling and forecasting also makes it possible to more effectively filter and interpret the great mass of partial and fragmentary or even contradictory data that gradually become available.
