Brier scores how well-calibrated the crowd was on each question: 0 is a perfect, confident, correct call · ~0.25 is a coin-flip · higher means the crowd leaned away from what happened. Computed from the crowd's own vote split vs what actually happened — no betting market involved.

0.15How far the crowd's whole picture sat from treating each question on its own. 0 = they answered independently; closer to 1 = the questions moved together.
Clustering on the top call1.6×The most-backed combination drew 1.6× as many voters as separate answers would predict — the crowd piled onto it together.
Rarity of the top call1-in-7The crowd put its top scenario at about 1-in-7; answering each question separately implies ~1-in-11. Shorter odds = more crowd conviction.

Crowd sentiment is shown only after a poll closes — never mid-vote. "Crowd called it" means the crowd's top pick matched the result; it is not a claim the crowd is right in general. Aggregate data from World ID voters — a crowd view, not a prediction or advice.
