The Persistent Echo of Retracted Science: 285 Latin American Papers Defy Removal

In the fast-paced world of scientific publishing, retractions are meant to be the ultimate safeguard—a formal declaration that a paper's findings are no longer trustworthy due to errors, fraud, or misconduct. Yet, a groundbreaking doctoral thesis from Brazil's Universidade Federal de Pernambuco (UFPE) reveals a troubling reality: even after being 'despublicados' or retracted, 285 out of 375 analyzed articles continued to be cited in new research and social media platforms. This 76% persistence rate underscores a critical vulnerability in the scientific record, particularly relevant for researchers, professors, and students navigating careers in higher education across Brazil and Latin America.
The study, led by Karen Isabelle dos Santos d'Amorim, highlights how retracted papers linger like digital zombies, potentially contaminating future work and eroding public trust. As Brazil's academic community grapples with pressures to publish amid limited funding, understanding this phenomenon is essential for maintaining research integrity.
Unpacking d'Amorim's Landmark Research at UFPE
Karen Isabelle dos Santos d'Amorim, now a professor in UFPE's Department of Information Science, conducted her analysis as part of her PhD in Information Science. Her thesis examined a 20-year span (2002-2022) of retracted articles authored by researchers from 14 Latin American countries, including Brazil, Mexico, Argentina, Colombia, and Chile. Published across 289 journals such as PLOS ONE, Scientific Reports, and Nature, these papers spanned health sciences, biological sciences, exact sciences, and humanities.
Winning the prestigious Capes Thesis Award 2025 in Communication, Information, and Museology, d'Amorim's work used the Altmetric Bookmarklet tool to track post-retraction mentions on platforms like X (formerly Twitter), YouTube, Facebook, Reddit, and Wikipedia, alongside traditional citations. This comprehensive approach revealed not just numbers, but the ongoing influence of invalidated science.Crafting a strong academic CV now demands vigilance against such pitfalls to advance in Brazil's competitive higher ed landscape.
Methodology: A Rigorous Dive into 375 Retracted Works
d'Amorim's methodology was methodical and multi-faceted. She curated a sample of 375 retracted articles from Latin American authors, verifying retraction notices and cross-referencing citations via academic databases. Social impact was quantified through Altmetric scores, capturing online buzz that traditional metrics miss. This hybrid approach—blending bibliometrics with altmetrics—provided a holistic view of how retracted research propagates.
- Series histórica analysis from 2002-2022.
- Geographic focus: 14 Latin American nations.
- Disciplinary breadth: Health, biology, exact, and human sciences.
- Tools: Retraction databases, Google Scholar, Altmetric for social citations.
Such transparency in methods sets a gold standard for Brazilian graduate students aiming for impactful theses. For those seeking research jobs in Brazil, demonstrating similar rigor is key.
Startling Statistics: 76% Still Cited Post-Retraction
The headline figure—76% or 285 articles—masks deeper trends. Health and biological sciences papers garnered the most post-retraction citations, amplified by pandemic-era interest. One stark example: a 2007 obesity-diabetes study retracted in 2016 amassed 221 citations afterward, with 80% treating its results as valid. Globally, Retraction Watch tracks thousands of such cases annually, but d'Amorim's regional lens spotlights Latin America's challenges.
| Category | Percentage |
|---|---|
| Misconduct/Fraud | 45.2% |
| Editorial Errors | 20.5% |
| Authorship Errors | 16.5% |
| Post-Retraction Citations | 76% |
These numbers signal systemic issues, urging Brazilian universities to bolster peer review training.

Root Causes: Fraud, Errors, and Systemic Pressures
Delving into triggers, 45.2% stemmed from misconduct like data fabrication or plagiarism, often reported by third parties (32.8%). Journals initiated 20%, spotting duplicates or unreviewed versions. Authorship mishaps, such as ghost authors, accounted for 16.5%. d'Amorim links this to the 'publish or perish' culture prevalent in Brazilian academia, where publications are currency for grants and promotions.
In Brazil, funding from CNPq and Capes intensifies this, mirroring global trends where retractions quadrupled in biomedicine over 20 years.
Real-World Cases: From Obesity Studies to Vaccine Myths
Consider the 2007 paper linking obesity to diabetes mechanisms—retracted for flaws, yet cited 221 times post-2016, mostly affirmatively. Globally, Andrew Wakefield's 1998 Lancet paper falsely tying MMR vaccine to autism lingers in denialist circles, retracted after a decade. In Latin America, health papers dominate, fueled by societal relevance.
Brazilian examples include manipulated images in ecology papers, echoing regional fraud patterns. These cases illustrate step-by-step propagation: initial citation ignores notice, subsequent works build on flawed data, amplifying errors.
Implications for Brazilian Higher Education and Research Integrity
For Brazil's universities, this erodes credibility, especially as international collaborations scrutinize records. UFPE's study spotlights local vulnerabilities, with health research most affected amid post-COVID scrutiny. Misinformation spreads faster than corrections, impacting public health policy and funding.
- Contaminates literature, leading to wasted resources.
- Fuels anti-science narratives.
- Challenges early-career researchers' trust in publishing.

Global Context: Rising Retractions Worldwide
Brazil's issues mirror globals: over 10,000 retractions in 2023 alone, many still cited. Retraction Watch notes highly cited retracted papers persist, with biomedicine hardest hit. In 2025-2026, AI-generated papers exacerbate risks.

Solutions: Teaching Integrity and Better Signaling
d'Amorim advocates: "It's crucial to discuss scientific integrity... taught from undergrad." Bidirectional retractions—for experts and public—plus enhanced notices in repositories. Brazilian unis could mandate ethics modules, reducing 'publish or perish' via quality incentives.
- Incorporate integrity in curricula.
- Improve retraction visibility (e.g., watermarks).
- Promote preprints with checks.
- Fund whistleblowers.

Future Outlook: Toward Cleaner Science in Brazil
With Capes recognizing such work, Brazil leads Latin America in addressing retractions. AI tools may detect fraud faster, but human vigilance remains key. For researchers eyeing jobs in Brazilian universities, prioritizing integrity boosts long-term success. As d'Amorim notes, confronting flaws strengthens science.
