The Evidence Ledger bronze

theevidenceledger.com

“The Evidence Ledger grades public claims -- health, science, and beyond -- on mechanism evidence and outcome evidence separately, so a plausible mechanism with no outcome data reads differently from a claim backed by both. Every grade cites its sources. Free to browse. Operated by Haygood Ideas, Inc.
