Public questions awaiting their deadlines.
We score the misses, too.
WorldPredicta launched its first public forecast cohort on July 30, 2026. No forecast has resolved yet, so any claimed accuracy number would be fake.
Not enough outcomes to judge performance.
Published after the first forecast resolves.
Requires a meaningful set of resolved probabilities.
A probability should be judged as a probability.
Brier score measures the squared distance between a forecast probability and the eventual yes-or-no result. Lower is better. Calibration asks whether events forecast at roughly 70% actually occur about 70% of the time.
Never delete a miss
Resolved questions remain in the archive with their original probability and evidence.
Use the first published result
Each forecast states whether later data revisions can change its resolution.
Separate domains and horizons
Performance will be reported by topic and time horizon, not hidden inside one flattering average.
Record model changes
When a miss changes the model, the version and reason will be published.
No resolved forecasts yet.
This is the honest starting line. The archive will populate when the published resolution rules reach their deadlines.
