"Making models to predict" is precisely the fluff that Taleb is against. There is no "if elections were held today", there are no do-overs, there is only one election. And you either win or lose (binary price [1]). So any prediction that doesn't incorporate the events between making the prediction until the election actually occurs, is worthless, or to be more precise: 50/50 (arbitrage free). The probability only goes up when you start counting the actual votes on Election Day.

- kelnos 6y agoIf it's 50/50 up until election day, then it's pointless to try to predict. And maybe that's Taleb's point. But is there value in a prediction that does try to predict using polling data and other information? If so, then regardless of whether or not 548 "does it right" by Taleb's definition, it's valuable, at least to some people.
