New Temporary Hobby: Participant in "Hybrid Forecasting-Persuasion Tournament" on Existential Risk Topics

The tournament is a research study, co-organised by Philip Tetlock (among other things, author of the airplane-reading book Superforecasting: The Art and Science of Prediction).

I should be spending at least three hours a week for three months thinking about existential risk topics (i.e. how things may go very very badly for humanity).

While it lasts, here's a link to the Call for Participants:

Here's an abstract on Reciprocal Scoring, a technique for (perhaps) getting better answers for not-objectively resolvable (here loosely termed "unanswerable") questions that underlies the tournament structure:
