Start here
Six steps, in order, and none of them take more than twenty minutes. If you only do one, do step two — a single scored forecast teaches more than a week of reading.
- 01Read the three pieces that set the tone
Slow thinking, prediction journals, and why small communities beat big platforms. Twenty minutes, and you will know whether this place is for you.
- 02Score one forecast in three questions
The Brier calculator asks what you think will happen, how sure you are, and what would change your mind. It takes a minute and leaves a number.
- 03Write one thing you are still thinking about
A question, a prediction, a half-formed idea. It does not need to be finished — it needs to be specific enough that someone can disagree with it.
- 04Keep the number somewhere you will find it
The prediction journal is the point of the whole site: write a probability and a deadline, then come back when the deadline passes.
- 05Ask a question we have not answered
Open Questions collects the ones this site has not settled, each with the evidence that would settle it. Add one, or argue with one.
- 06Read the rules before your second post
Short, and mostly about the same thing: write your own words, argue with the strongest version of the other side, and give people time.
