A paper citing nothing from the last five years is either reviewing settled history or has not engaged with current work.
A paper citing nothing from the last five years is either reviewing settled history or has not engaged with current work. A paper citing almost nothing older than five years may be missing the foundational results its claims rest on.
Authors cite their own prior work legitimately, because research is cumulative. A reference list where a large share points at one group is a signal to check whether the claim is supported outside that group.
The most common citation error is a reference that does not support the sentence attached to it. Following two or three citations in any paper is a fast and unusually revealing check, and it frequently finds a claim resting on a source that said something weaker.
Authors cite a paper for a claim they read in another paper's description of it. A misdescription can then travel through a literature for years, gaining apparent authority with each repetition while nobody rereads the original.
A list made mostly of reviews rather than primary studies means the authors are reporting consensus rather than evidence. That is appropriate for background and not for the central claim of a paper.
A paper engaging with work that disagrees with it is doing something a paper citing only supportive sources is not. Absence of any contrary citation in a contested area is itself a finding about the paper.
Citations to journals with no visible review process weaken the chain regardless of the citing paper's quality. Checking two or three unfamiliar journal names takes a minute.
Scan the list before the body. Three questions — how recent, how self-contained, and does it engage with disagreement — place a paper faster than reading its introduction.
The most common citation error is a reference that does not support the sentence attached to it. Checking two takes a few minutes and is unusually diagnostic of how carefully a paper was assembled.
A paper engaging with work that disagrees with it is doing something a paper citing only allies is not. In a contested area, no contrary citation at all is itself a finding.
