OUR TAKE / EDITORIAL OPINION

Good Judgment Open makes revision part of participation

The useful habit is writing down what would change your mind.

Prediction AI Tools editorial desk · Reviewed Oct 8, 2026

Good Judgment Open presents public forecasting questions and a participation workflow across geopolitical, economic and policy topics. Our take is that the platform is most interesting as a place to practice accountable uncertainty. We would approach a question by making an explicit estimate and recording the evidence that could change it, rather than treating participation as a contest in sounding certain.

We would consider it for someone who wants a repeatable forecasting habit with questions beyond a single market category. The tradeoff is the structure of shared questions versus the temptation to focus on relative standing before understanding one’s own reasoning. We would give a careful explanation of a revision more weight than an impressive isolated result.

An evaluation should follow a small number of clearly defined questions over time. For each, keep a dated note of the estimate, the strongest contrary evidence and a trigger for reconsideration. Review the final outcome alongside those notes rather than judging the last estimate alone. We have not measured any improvement from using the platform. Our criterion is whether the participation process makes reasoning easier to revisit and mistakes easier to describe; that is a more useful starting objective than assuming a forecasting reputation will follow.
