Andreas Graefe presented a post-mortem of the forecasting of the 2016 U.S. Presidential Election at TEDxMünchen. Andreas discussed why most of the methods used to predict the Clinton-Trump election result were more wrong than usual, and introduced the PollyVote. As regular visitors to this site know, PollyVote combines many forecasts in order to incorporate more knowledge and information, but also to reduce the chances of being badly wrong.
