Summary:

Of course, as I point out in my forthcoming book Quantum Economics, economics should not be compared directly with weather forecasting. For one thing, the fact that economists’ predictions and models affect the economy (the financial crisis of 2008 for example was in part caused by faulty economic risk models) means that their responsibility is more like that of engineers or doctors. Instead of predicting exactly when the system will crash (no one has ever asked for a precise ‘date’), they should warn of risks, incorporate design features to help avoid failure, know how to address problems when they occur, and be alert for conflicts of interest and ethical violations.

The profession’s failings in these areas, rather than any particular forecast, are the real reason so many are calling for a genuinely new paradigm in economics, as opposed to a rehashed version of the old one....

The Economics Debate: The Problem isn’t Bad Economics, It’s Bad ScienceDavid Orrell is an applied mathematician and author of popular science books. He studied mathematics at the University of Alberta, and obtained his doctorate from Oxford University on the prediction of nonlinear systems. His work in applied mathematics and complex systems research has since led him to diverse areas such as weather forecasting, economics, and cancer biology.
