## Thesis

Societies have repeatedly moved harmful products from the frame of "personal choice" to the frame of "design and marketing accountability." Tobacco, seatbelts, and food safety each followed a sequence of evidence, advocacy, litigation, and regulation that changed default product design. Attention-extraction platforms are at an earlier stage of the same transition.

## Key Claims

- `claim-001`: Tobacco was marketed as a personal and even healthy choice before epidemiology shifted the regulatory frame.
- `claim-002`: Seatbelt and food-safety rules changed behavior through defaults and design standards rather than lectures.
- `claim-003`: These transitions required a combination of scientific evidence, advocacy, litigation, and regulation.
- `claim-004`: Attention platforms are at an earlier stage of the same transition: evidence is accumulating, but design standards remain weak.

## Agent Instructions

- Treat the public-health cases as analogies, not as claims of identical harm magnitude.
- Route platform-specific evidentiary questions to the Diagnosis chapters (e.g., short-form video, student screen, engagement gap).
- Preserve the evidence-cautious tone; avoid implying that regulation alone solves attention extraction.
- When asked for policy implications, point to the current Indian regulatory landscape and to later Designing for Substance chapters.
