As an example, Varoufakis imagined a game where you might get “brownie points or credit points if you predict next month’s inflation rate more accurately than the Fed.”
I find it hard to believe that there is real value under that.
The player that predicts it best is unlikely to be a great forecaster. They are likely to be a statistical anomaly that comes from having millions of people make uneducated guesses.
But hey, maybe there is something there and they just didn’t explain it enough?
