Our source hierarchy
- Primary authority: statutes, regulations, regulators, official agencies, standards bodies, program owners, and original datasets.
- Original research: peer-reviewed papers, technical reports, and transparent surveys with methods we can assess.
- Expert interpretation: established professional or academic sources used to explain—not replace—the primary record.
- Secondary reporting: reputable reporting used for context or to locate primary material, not as the only support for consequential advice.
How links appear
Important sources are linked near the claim they support. Every guide also includes an evidence record with the publisher, title, use, and date checked. External links open in a new tab and do not imply endorsement of every statement on the destination site.
What we generally avoid
- Anonymous summaries that do not identify their evidence.
- Affiliate pages when a regulator, standard, dataset, or manufacturer document is available.
- Search snippets, AI answers, and social posts as factual sources.
- Statistics without a date, denominator, method, or original publication.
- A single national figure presented as a guaranteed local result.
Link maintenance
Links are checked during review. If an authority moves a page, we update the destination without silently changing the article’s conclusion. If the underlying evidence changes, the article receives a substantive review.
Original editorial imagery
Images created for Everyday Fieldbook are illustrative editorial assets, including AI-assisted still-life scenes. They do not depict a specific product, provider, patient, result, or promised outcome. We do not use before-and-after composites to imply results, and an image never replaces the evidence cited in a guide.
