Methodology
Brier score measures forecast accuracy: the squared difference between the predicted probability and the actual outcome (0 or 1). Lower is better. A Brier score of 0 is perfect; 0.25 is equivalent to a coin flip.
Calibration measures whether predicted probabilities match observed frequencies. A forecaster who says "70% likely" should be right about 70% of the time. Calibration is calculated as 1 - |average predicted probability - actual outcome rate|.
AI Consensus is the simple average of all bot forecasts for a given market. Hybrid is the average of the human consensus and AI consensus probabilities — testing whether combining human and AI views produces better forecasts than either alone.
Performance is calculated only on objectively resolved events— markets that have been settled with a clear YES or NO outcome. Unresolved or voided markets are excluded from all calculations.
This comparison is powered by our open-source Space Weather Forecast Benchmark on GitHub — public datasets, transparent scoring, and a live leaderboard. Anyone can submit forecasts and verify the results.
