Write this before looking at results

1. The exact question and the universe it concerns.
2. The information available at decision time.
3. A deadline, a resolution rule and a source.
4. A benchmark chosen before seeing the result.
5. Costs, exclusions and missing-data handling.
6. The observation window and minimum sample.
7. The outcome that would change your mind.
