The Calibration Tournament
Vol. I · No. 0 · July 2026

TheCalibrationTournament.

Ten weeks. Ten questions a week. You submit a number between 1 and 99 — your honest confidence. The math punishes overconfidence and rewards being right about uncertainty.

Whoever ends the season closest to reality wins. Whoever ends furthest faces the group’s chosen consequence.

§ How it works

You aren’t picking winners.
You’re putting a number on your honesty.

01 ◊

Ten questions

Real-world events that resolve in the next seven days. Mix of sports, markets, news, and wildcards.

02 ◊

Your number

For each one: a probability from 1 to 99. The closer to reality, the lower your Brier score. Lower is better.

03 ◊

Locked forever

Submission is one-shot. No edits. Sunday it all resolves and you find out exactly how calibrated you are.

§ Standings

The board, so far.
