Platform Impact Profiles
Each platform profile documents the cognitive and mental-health effects established in peer-reviewed research, alongside the entity that owns or controls it.
Cognitive Harm Footprint Leaderboard
A transparent 0–100 score per platform combining documented harm count, severity weighting (suicide/addiction/radicalisation rank highest), reach, and the presence of engineered mechanisms. The algorithm is open and reproducible — see scoring methodology.

Mechanisms of Harm
The specific UI/UX design patterns that drive these outcomes. These are deliberate engineering choices that erode user agency by design.
Accountability Map
Documented ownership links between Closed-Loop individuals and the platforms whose harms are catalogued here. Each link follows from public records to peer-reviewed harm.

Why this matters
When an owner says "my platform connects people," the public record now answers with the citations: the documented anxiety, the documented attention loss, the documented adolescent brain changes. This database does not invent claims; it curates the established scientific consensus and ties it to the people who profit from the design choices that produce it.
