Once a journal publishes a research paper, other researchers can keep citing that work and build on it to produce more research. So simply withdrawing a faulty paper does not correct the research record: the work based on it also needs to be checked and, if necessary, undone. Because it contains a mistake or, as is increasingly the case, it was produced by fraudulent means, sometimes, this continues even after, say, the journal withdraws the original paper.
A retraction is meant to inform other scientists that the data and inferences reported in a study are incorrect. In fact, Dr. “When errors in science are inadvertent, the errors get corrected when the experiment is repeated by the scientist who committed the error or by another scientist. Thereafter, the erroneous results of the experiment do not influence scientific practice,” Dr. That process, however, may never occur in every case. Majumder, no scientist may be willing to study the same problem addressed in a retracted paper and generate correct data and inferences.
Because that information spreads slowly, he said he believes a retraction will have broadly achieved its purpose when about 90% of researchers in that field are aware of it, although complete awareness is impossible to ensure.
Majumder said when a retraction can be said to have achieved its purpose is itself “very difficult” to determine. Majumder said. According to Dr. “Therefore,” he added, “the scientific record may never be corrected.”
More research papers are being retracted than ever before. She added that a stronger research integrity system would identify whether the problem was fraud, an honest error or failure of replication — and use those lessons to make peer review (the process where independent scientists check the work of others in their field), data-sharing practices, and institutional accountability better. Because researchers are also publishing more papers today — and because stakeholders, like journal editors and independent experts, are scrutinising papers more carefully, this is.
In 2025, his team analysed data of life-sciences papers retracted between 1981 and 2023 — and found that the reasons for retraction included non-compliance with ethical standards, plagiarism, data-related concerns, and publication misconduct. In a 2026 study , research scholar P.R. Devanath and associate professor Rupesh Kumar of Tumkur University, Karnataka, analysed more than 12,000 citations of papers funded by the Indian government and later retracted. And found that 30% of the citations had been incurred after a paper was retracted. And nearly 64% of those second-generation papers were authored by the same groups, i.e. they had self-cited.
An expert on research ethics at the Institute for Stem-cell Science and Regenerative Medicine, Bengaluru, retractions have increased substantially over the last four decades, according to Sabuj Bhattacharyya. They also identified a “cascading retraction effect” in which some retracted papers continued to be cited by studies that were themselves later retracted.
There is no easy way to identify unreliable papers much earlier, although researchers are increasingly using artificial intelligence (AI) tools to flag problem papers, she added.
