- Core idea
- People expect small samples to look like perfect miniatures of the population and wildly overinterpret streaks and blips.

- Best for
- Anyone who has ever panicked over a week of metrics or a five-game losing streak.
- Length feel
- Shortish, sharp, and to the point—like a very stern memo to your inner analyst.
