How Evidence Is Categorized and Tagged
This guide explains how posts are categorized and tagged in the library. Tags are used to
describe what was studied and how it was studied, not what readers might want the study to
imply.
Categories describe content purpose
Categories group posts by function (for example, Guides & FAQs versus study summaries).
This keeps navigation consistent and prevents background content from being mixed into
evidence archives.
Tags describe model type and subject
Tags may indicate model type (for example, in vitro) or subject (for example, a constituent).
Model-type tags are applied conservatively. Review or chemistry-only posts are not tagged as
in vitro unless they directly report assay work.
Why conservative tagging is used
Over-tagging inflates the apparent evidence base and makes archives misleading. This library
prioritizes accuracy over volume. If a category looks smaller than expected, that is usually
a sign the tagging is working as intended.
What to do if a tag archive looks empty
Empty archives generally indicate that qualifying literature has not been identified, not
that the site is unfinished. Where useful, the site includes short context posts to explain
gaps without filling them with assumptions.
