Century Forecast

What happens to us next?

An auditable forecast journal. Ask about anything — school, rent, your job, cars, the Moon — and see the estimate, the evidence on both sides, and every time it changed.

65 questions tracked across 14 domains. 17 carry a probability so far — the rest are deliberately empty, because a number without evidence behind it is worth nothing.

Forecast in depth

Where the evidence has actually been gathered. Each carries its reasoning, the evidence on both sides, and every revision.

Every question tracked

Including the ones with no number yet. An empty cell is a question we have opened and not yet answered — it is not a forecast of zero.
