> HTML: https://siren.watch/guides.html

Search often lands on a doom score, a countdown, or a DEFCON-shaped novelty page.
These pages answer the vocabulary questions without inventing a probability of harm.
SIREN stays an hourly activity count with a receipt.

## Guides

- [How does SIREN compare to DEFCON, the Doomsday Clock and p(doom)?](https://siren.watch/guide.html): Activity tempo vs readiness, symbolic clocks, opinions and title hijack — what each measures.
- [What is p(doom)?](https://siren.watch/p-doom.html): Named estimates on one chart. An opinion expressed as a percentage, not a receipt.
- [Is there an AI doomsday clock?](https://siren.watch/ai-doomsday-clock.html): The Bulletin’s clock vs AI-specific countdowns vs an hourly activity count.
- [How the SIREN AI activity index is computed · methodology](https://siren.watch/methodology.html): Every formula, pillar weight, and frozen-reference rule.
- [What is the history of AI risk?](https://siren.watch/history.html): Dated, sourced field notes — Good, Asilomar, the pause letter — not a forecast.

- [Which AI indexes does SIREN contrast?](https://siren.watch/vs.html): Directory of honest versus pages — activity tempo, not doom claims.
