Glossary/Literature review grades

Contested (literature)

A published critique, failed replication, or retraction lead targets the supporting record. A finding, not noise.

The definition the product enforces, read from the same code the methodology page renders.

How to read it

When Contested appears on a page

A published critique, a failed replication or a retraction lead targets the supporting record. Not noise: a finding about the finding.

The family

Literature review grades

What a body of studies is allowed to be said to show, and whether the question was studied as asked.

Convergent (literature)At least two INDEPENDENT named studies — different teams or datasets — point the same direction. The only grade that earns "the literature shows".Single study (literature)One named study only. A real measurement, but one measurement — never "the literature".Preliminary (literature)A preprint, pilot, working paper or small-n result that has not been replicated or peer-validated. Marked as what it is.Mixed (literature)Named studies genuinely disagree. The split is the finding; the sides are named, never averaged.Not established (literature)The claim circulates — in coverage, marketing or folklore — without a study behind it that this review could find.Directly studied (answerability)The literature studied this question as asked.Adjacent only (answerability)The literature studied related questions — proxies, narrower populations, different timescales. Every finding names what was actually studied.Unstudied (answerability)No study addresses the question. Saying so IS the review.
