Glossary/Literature review grades

Adjacent only (answerability)

The literature studied related questions — proxies, narrower populations, different timescales. Every finding names what was actually studied.

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

How to read it

When Adjacent only appears on a page

The literature studied related questions: proxies, narrower populations, different timescales. Every finding on the page names what was actually studied, so the distance from your question is visible.

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.Contested (literature)A published critique, failed replication, or retraction lead targets the supporting record. A finding, not noise.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.Unstudied (answerability)No study addresses the question. Saying so IS the review.
