Methodology

Why our signal can be
trusted.

Calibration over confidence. Verifiable scores over self-promotion. Here's how we keep forecasters honest.

Calibration curve
Metaculus Community
96.1% calibrated
Calibration curve — predicted probability vs. observed frequency02550751000255075100Predicted probability (%)Observed frequency (%)
Perfect calibration
Forecaster actual

When this forecaster says 70%, it happens ~70% of the time.

That's calibration — and it's the only test that matters for a forecaster. Anyone can sound confident. Few are right at the rate they claim. We measure that. Publicly. On every prediction.

Brier Score
Mean squared error between predicted probability and resolved outcome. Lower is better. 0.082 is the current top score.
Calibration
Of predictions made at X% confidence, how often did they actually resolve true? Plotted as the curve on the left.
Sharpness
How far from 50% does a forecaster commit? Confident predictions are valuable — when they're right.
Coverage
AI models and human forecasters are scored on identical questions. No category gaming.
