I’d like to become better calibrated via PredictionBook and other tools, but coming up with well-specified predictions can be very time-consuming. It’s handy to be provided with a stock of specific claims to make predictions (or post-dictions) about, as with CFAR’s Credence Game.
Therefore, I asked Jake Miller and Gwern put together a list of prediction sources. Feel free to suggest others!
