What the evidence says

six tiers, never blended

preclinical — animal, cell or mechanistic work — not yet about people

every claim resolves to its source

All 1 citation resolves to their original source. · 0 posts naming it, 0 members counted once each.

Evidence, kept apart

The Atlas never mixes evidence types into one blob. Each claim below carries the tier it actually sits in; an unresolved citation is shown and does not move the page.

failure is information

Nobody has filed a failure yet. Failures are information; this list is waiting for an honest one.
