Trace claims back to their original evidence

Finding a link is not the same as showing that it supports a claim. Specify the jurisdiction, date range and kind of evidence needed, and inspect the original sources yourself.

A comparison checklist

• Prefer primary sources for policy, product terms, legal rules and study results.
• Check whether a quotation supports the exact claim rather than a related topic.
• Record dates, limitations and unanswered questions; distinguish absence of evidence from evidence of absence.

A reproducible task to adapt

Request a claim-to-source table for a narrow public question. Open each cited source and check the quoted passage. A real citation can still be outdated or interpreted incorrectly.

These are editorial selection criteria, not results from testing every listed service. Entries without a source-checked detail page open the provider directly. Their pricing labels are existing directory records, not a current-price guarantee.
