At the recent International Symposium of Forecasting in Riverside, Scott Armstrong and Kesten Green presented three papers illustrating the effects of simplicity and conservatism in forecasting. In one example, with Andreas Graefe, they described applying three Golden Rule checklist items to improving eight established election forecasting models. Their resulting simple model reduced forecast error by 45% compared to the original models.
