Measure is unceasing

Forecasting Newsletter: April 2020

A forecasting digest with a focus on experimental forecasting.

The newsletter itself is experimental, but there will be at least five more iterations. Feel free to use this post as a forecasting open thread.

Why is this relevant to EAs?

Conflict of interest: With Foretold in general and Jacob Laguerros in particular. This is marked as (c.o.i) throughout the text.


Prediction Markets & Forecasting platforms.

Forecasters may now choose to forecast any of the four horsemen of the Apocalypse: Death, Famine, Pestilence and War.


Augur is a decentralized prediction market. It will be undergoing its first major update.

Predict It & Election Betting Odds: &

Anecdotically, it often has free energy, that is, places where one can earn money by having better probabilities, and where this is not too hard. However, due to fees & the hassle of setting it up, these inefficiencies don’t get corrected. In PredictIt, the world politics section…

The number of questions is small, and the current trading volume started at $8000, but may increase.

Good Judgement Inc. is the organization which grew out of Tetlock’s research on forecasting, and out of the Good Judgement Project, which won the IARPA ACE forecasting competitionProgram), and resulted in the research covered in the Superforecasting_ book.

The Open Philantropy Project has funded this covid dashboard by their (Good Judgement Inc.’s) Superforecasting Analytics Service, with predictions solely from superforecasters; see more on this blogpost.

Good Judgement Inc. also organizes the Good Judgement Open (\[[](\], a forecasting platform open to all, with a focus on serious geopolitical questions. They structure their questions in challenges, to which they have recently added one on the Coronavirus Outbreak; some of these questions are similar in spirit to the short-fuse Metaculus Tournament.

Of the questions which have been added recently to the Good Judgment Open, the crowd doesn’t buy that Tesla will release an autopilot feature to navigate traffic lights, despite announcements to the contrary. Further, the aggregate…
