Phase 2 census · what later papers do with a retracted study

40.7% of citations to retracted papers still treat them as support.

Out of every 100 citations made after a paper was retracted, 41 treat it as support, 56 mention it in passing, and just 3 flag it as retracted or unreliable.

51,626 citations to 12,328 retracted papers, each made in a year after the retraction. Left out: 4,044 citations to paperwork retractions (no fault found in the science) and 18 the three readers could not decide. Not corrected for reader error. Corrected using one AI reader's checks of 150 citations, the estimate is 38.1% (95% CI 33.5–41.8%). 95% confidence intervals (the likely range) come from re-running the numbers 400 times, drawing whole retracted papers at random (a cluster bootstrap).

Phase 2 census · does time fix it?

34.9% of citations still treat a retracted paper as support more than ten years later.

In the first two years after a retraction it is 43.6%. Only a few in a hundred ever flag the paper as retracted or unreliable.

Each bar mixes papers retracted in different years. Recent retractions can only appear in the early bars, so part of the drop comes from which papers are old enough to count.

Phase 2 census · was the warning on the page?

2 in 5 citations still treat a retracted paper as support, even when the citing paper's published reference list shows the retraction.

That is 40.4% of 3,628 such citations, about the same as for all citations (40.7%). Only 12.9% flag it as retracted or unreliable in the text.

“Reference list says retracted” means the word “retract” appears in the citing paper's own reference entry for the work. Most entries carry a clear mark: a title prefix such as “RETRACTED:” (2,664) or a retraction note (523). The other 441 mention it in other formats. On the 3,187 clear marks alone, 41.5% (1,322) cite the work as support. The mark may come from the authors' reference software or from the journal. 95% confidence intervals (the likely range) come from re-running the numbers 400 times, drawing whole retracted papers at random (a cluster bootstrap).

Phase 2 census · does the reason matter?

Only 1.9% of citations to papers retracted for misconduct flag them as retracted or unreliable.

For papers retracted for error it is 6.5%. Both are still cited as support about 4 times in 10 (41.2% and 40.0%).

Flagged it as retracted or unreliable, by reason for the retraction

Misconduct and error are still cited as support about as often: 41.2% and 40.0%.

Reason groups follow the Retraction Watch reason codes. Paperwork retractions (out of date, replaced, moved journal, publisher duplicate) find no fault in the science and are reported apart. 95% confidence intervals (the likely range) come from re-running the numbers 400 times, drawing whole retracted papers at random (a cluster bootstrap).

Phase 2 census · is it one field's problem?

In every subject, 31% to 43% of citations to retracted papers still treat them as support.

From biology and medicine to the physical and social sciences, business and the humanities. Only 1.7% to 4.1% flag the paper as retracted or unreliable.

Treated it as support, by subject of the retracted paper

A paper can have more than one subject; its citations count under each. Humanities rests on 194 citations, so it is the least certain.

The registered rule's code pattern skipped the business and technology code (B/T), so 82 citations to papers coded only B/T are left out of its groups; they are in the table, not drawn, and counted in the subject breakdown. 95% confidence intervals (the likely range) come from re-running the numbers 400 times, drawing whole retracted papers at random (a cluster bootstrap).
