Science flags paper that found AI chatbots help debunk conspiracy theories 

Science has issued an expression of concern for a highly publicized study looking into whether conversations with AI chatbots could convince conspiracy theorists to abandon their beliefs. The move came after the authors of the paper found inconsistencies in their dataset, but a reanalysis shows the findings still stand, they say. 

The September 2024 article found conversing with an AI chatbot called DebunkBot reduced people’s belief in a particular conspiracy theory by an average of 20%. The research was featured in news stories in The New York Times, Washington Post and The Atlantic. 

This February, the authors — Thomas Costello of Carnegie Mellon University in Pittsburgh, psychologist Gordon Pennycook of Cornell University in New York and cognitive scientist David Rand at the Massachusetts Institute of Technology — won the Newcomb Cleveland Prize from the American Association for the Advancement of Science, which publishes Science, for the work. It has been cited 192 times, according to Clarivate’s Web of Science.

New system for flagging retracted papers finds scores of them in Cochrane reviews

Cochrane has implemented a new system for checking whether any of its thousands of published reviews include retracted studies in their analyses, the organization announced today. The effort already has turned up dozens of reviews that do and will now get closer scrutiny to ensure their results and recommendations hold up.

Cochrane publishes systematic reviews on health-related topics that evaluate the strength of evidence on particular treatments and interventions. Professional organizations and policymakers use the more than 9,500 reviews when developing recommendations. Recently a study of anesthesia clinical trials found a high rate of the studies with faked or flawed data, and another revealed that retracted studies included in systematic reviews — 17% of which were Cochrane reviews — had a large impact on clinical guidelines derived from them. 

Last year, Cochrane rolled out a feature in its database of reports of clinical trials, called CENTRAL, to flag retracted studies. The publisher pulls data on retracted papers from the Retraction Watch Database, via CrossRef. Now, they have extended the process to routinely identify systematic reviews that rely on retracted papers.

Journal retracts depression treatment study with findings called ‘too good to be true’

In the fall of 2024, Matt Williams was grading papers at Massey University in New Zealand when he noticed something off in a study one of his students had cited.

The study, published in 2016, reported overwhelming evidence suggesting that eye movement desensitization and reprocessing, or EMDR, is an effective treatment for depression. But the roughly 85% drop in symptoms of depression linked to the therapy struck Williams as implausible. 

“That’s way too big to have that kind of effect,” Williams recalled thinking as his first impression of the study. “Because I love to procrastinate instead of continuing marking, I then looked up the paper and started reading it.”

Court dismisses biochemist’s lawsuit against MD Anderson

A Texas court has dismissed a lawsuit by a biochemist accused of research misconduct who claimed her former institution violated her due process rights during its investigation. 

Sonia Melo sued The University of Texas MD Anderson Cancer Center in Houston in 2025, alleging the institution failed to follow its policies during a misconduct investigation into her work. MD Anderson found in May 2024 Melo had engaged in research misconduct while a postdoctoral fellow between 2012 and 2014, according to court documents.

Attorneys for MD Anderson requested a judge dismiss the suit in February, arguing the institution is a governmental entity entitled to sovereign immunity that protects it from lawsuits seeking money. Under Texas law, public hospitals are shielded from most suits by immunity rules. Some loopholes for medical negligence exist, such as when medical equipment harms patients.

Editors of semantics journal resign, launch new journal after publisher ‘ultimatum’

The new journal, Semantics of Natural Languages, launched in May.

The editors of a semantics journal owned by Springer Nature have resigned to launch a new one, citing pressure from the company to increase their annual publication volume by 25%. 

The editor-in-chief and the two associate editors Natural Language Semantics resigned from the journal in early April, editor-in-chief Amy Rose Deal, a linguistics professor at the University of California, Berkeley, told Retraction Watch. They resigned in consultation with the 25-member editorial board, which gave “a very high level of support for the move,” Deal said.

In a May 19 open letter, the three resigning editors and the founding co-editors of Natural Language Semantics announced the launch of their new journal, Semantics of Natural Languages. The new journal is published by the Open Library of Humanities, an open-access publisher whose goal “is to liberate university research from commercial control,” according to its website.

Journal retracts study linking hepatitis vaccine to autism that was included in CDC review

A toxicology journal has retracted a 16-year-old study linking hepatitis B vaccines to autism in children following an independent statistical review that found a half-dozen concerns with the study’s methodology.  

Using data from the National Health Interview Survey, the authors claimed boys vaccinated in their first month of life had “threefold greater odds for autism diagnosis” than those vaccinated later or not at all. 

The study was included in a rapid systematic review of hep B vaccine studies presented by John Su, director of the Immunization Safety Office for the Centers for Disease Control and Prevention, at the Sept. 18 meeting of the Advisory Committee on Immunization Practices.  It resurfaced in a presentation at the Dec. 4 ACIP meeting, just before the committee’s decision to no longer recommend that infants receive the hep B vaccine at birth if the mother tests negative for the virus.

Journal retracts paper criticizing parental alienation theory after group threatens to sue

A humanities journal has retracted an article about the controversial theory of parental alienation after receiving legal threats from a group that supports the concept. 

On May 19, the Integrated Journal for Research in Arts and Humanities (IJRAH) removed a review article by Robert Keith Head suggesting the theory of parental alienation is unsupported by research and fails “to meet basic validity requirements for psychological constructs.” 

The move came after the Parental Alienation Study Group (PASG) — which describes itself as an international, nonprofit membership organization dedicated to the study and understanding of parental alienation — accused the journal of publishing “scientific fraud” and demanded the journal retract the paper or face legal action. The journal said the removal was not dictated by “external demands or threats” but followed a “comprehensive secondary evaluation” by its editorial board and independent psychometric experts who identified “critical methodological and structural flaws that undermined the paper’s scientific validity.”

In what EIC calls an ‘honest mistake,’ journal approves paper without peer reviewing it

For most researchers, having an article accepted comes with constructive feedback from editors and reviewers. But when a sociology researcher learned his article was accepted at a Taylor & Francis journal, he was surprised to find the journal had skipped the peer review process altogether. 

Martino C. submitted his article on the effects of economic instability on political ideology in Slovakia to the journal Democracy and Security on October 15. (We’ve withheld the author’s last name at his request for digital privacy reasons.) He told Retraction Watch he was hoping peer reviews would help him improve his argument. 

But on January 13, the paper was marked “Accepted” in the journal’s submission portal without feedback.
