Knockouts excluded

Human Actually published on-the-record picks for the 72 group-stage matches only. The 32 knockout matches (LAST 32 through Final) were not on the lab slate and are excluded from the Human Actually calibration total — not because outcomes are missing, but because no lab prediction existed.

  • High-confidence calls (≥80%) were mostly earned: 7 correct, 2 wrong.
  • Low-confidence calls (≤60%) were near coin-flip: 16 correct, 17 wrong — appropriate caution.
  • The expensive misses clustered on favorites that drew: stated confidence for a win collided with a 0–0 or 1–1.
  • Average stated confidence (65%) sat below the public crowd (78%), and the lab’s calibration score finished higher.

How to read this

There is no tournament “winner” among forecasters. The Calibration Cup grades confidence against reality. A higher Calibration Score means stated probabilities lined up better with what happened. Full methodology: How scoring works. Interpretation: Read the conclusion.
