How these fact checks are made
This section collects plain-language summaries of well-established, evergreen questions in science, health, and popular myths. Every entry describes a finding that was originally published by an independent, established fact-checking organization — we summarize that finding in clear language and link prominently to the original review so you can read it yourself.
What we do — and don't — claim
FactGuard does not author the verdicts in this section. We act as a host and summarizer: we rate the claim, never a person, and we attribute every finding to its original publisher. We don't publish checks about named living individuals, elections, or active legal matters here.
How the rating scale works
Each check shows a verdict on a five-point scale. The visible badge and the page's structured data are generated from a single shared function, so they always match:
- False (1 of 5) — the evidence does not support the claim.
- Mostly false (2 of 5) — mostly unsupported, with a kernel of accuracy.
- Half true (3 of 5) — supported only in part.
- Mostly true (4 of 5) — largely supported, with caveats.
- True (5 of 5) — the evidence supports the claim.
Sourcing and attribution
Every page names the original publisher, links to the original review, and lists the sources behind the finding. For more on how FactGuard's verification engine works generally, see our methodology.
