Science University uses visible references so readers can inspect the evidence behind important factual claims and continue reading beyond the summary on the page.
Preferred sources
Depending on the subject, strong sources may include peer-reviewed research, systematic reviews and meta-analyses, major scientific agencies, public-health bodies, professional scientific organizations and established academic reference works.
Source matching
A citation should support the specific claim placed near it. A reputable source is not enough if it does not actually establish the statement being made.
Primary and secondary evidence
Primary studies are useful for specific findings, while high-quality reviews and consensus documents are often better for describing the overall state of evidence. Articles may use both where that produces a more accurate explanation.
Link maintenance
External pages can move. When a citation link becomes obsolete, the editorial team should replace it with a current canonical source where possible without changing the meaning of the article.
Corrections
If you find a source that does not support the associated claim, please report it through the Contact page. Confirmed problems are handled under the Corrections Policy.
