A verified information layer that labels and links cancer content across platforms
Wherever cancer information appears online, a visible marker shows whether it matches what trusted sources say, with a one-click link to the plain-language evidence.
Platforms label some health content but coverage is thin and inconsistent. The proposal is an open, machine-readable registry of vetted cancer claims and sources (national cancer institute, cancer charities, guideline bodies) that platforms, browsers and AI assistants can query, delivered as a browser extension and platform API, with labels that link to plain-language summaries and disclose the sourcing. Independent governance keeps it credible.
Hypothesis
Content carrying the verified label is trusted and shared more, and exposure to labelled contradictions reduces belief in false cancer claims in randomised exposure studies.
Rationale
Credibility signals work when they are consistent, independent and easy to check; the missing piece is a shared open registry rather than each platform improvising.
What would test it
Build the registry for 500 common claims; randomised online experiment measuring belief and sharing with and without the layer; then a browser extension pilot with patient organisations.

Bottlenecks it attacks
- Misinformation and unproven therapies · Patients are sold unproven treatments and frightened away from proven ones.
- Knowledge reaches practice too slowly · Knowledge diffusion is slow: it takes years for a proven result to change what most patients receive, and no one can keep up with the literature.
