An observatory dome under a clear night sky

Written down first. Checked after.

Forecasts are logged before the outcome is known, and findings can be run again by anyone.

Why it matters

Most forecasts are judged by the people who made them.

A model that is never scored in public can claim anything. Most are tuned after the fact, and the misses fade from view.

We write every forecast to a ledger before anyone knows the answer, score it against what happened, and sign our findings so others can run them again from the same data.

How we work.

Register
We write down the question and the method before we see the answer.
