10 years after the downfall of a same-sex marriage canvassing study, tenure, some better practices — and an engagement

A study on how conversations can change minds grabbed headlines when it was published — and again five months later when retracted.

“Gay Advocates Can Shift Same-Sex Marriage Views,” read the New York Times headline. “Doorstep visits change attitudes on gay marriage,” declared the Los Angeles Times. “Cure Homophobia With This One Weird Trick!” Slate spouted.

Driving those headlines was a December 2014 study in Science, by Michael J. LaCour, then a Ph.D. student at the University of California, Los Angeles, and Donald Green, a professor at Columbia University.

Researchers praised the “buzzy new study,” as Slate called it at the time, for its robust effects and impressive results. The key finding: A brief conversation with a gay door-to-door canvasser could change the mind of someone opposed to same-sex marriage. 

By the time the study was published, David Broockman, then a graduate student at the University of California, Berkeley, had already seen LaCour’s results and was keen to pursue his own version of it. He and fellow graduate student Joshua Kalla had collaborated before and wanted to look more closely at the impact canvassing could have on elections. But as the pair deconstructed LaCour’s study to figure out how to replicate it, they hit several curious stumbling blocks. And when they got a hold of LaCour’s dataset, or replication package, they quickly realized the results weren’t adding up.

Fourth retraction for Italian scientist comes 11 years after sleuths flagged paper

PLOS One has retracted a 2011 paper first flagged for image issues 11 years ago. The retraction marks the fourth for the paper’s lead author, Gabriella Marfè of the University of Campania “Luigi Vanvitelli,” in Caserta, Italy. 

Involvement of FOXO Transcription Factors, TRAIL-FasL/Fas, and Sirtuin Proteins Family in Canine Coronavirus Type II-Induced Apoptosis,” has been cited 41 times, according to Clarivate’s Web of Science. 

Elisabeth Bik flagged the article on PubPeer in 2014 for apparent image manipulation and duplication in six figures. In a 2019 email to PLOS staff, pseudonymous sleuth Claire Francis drew attention to Bik’s findings. The journal retracted the paper on May 6 of this year.

IQ study retracted in fallout from decades-old misconduct report

The authors of a paper on how motivation influences  intelligence test scores have retracted their paper following the retraction of a 50-year-old study included in their analysis. 

Part meta-analysis and part longitudinal study, “Role of test motivation in intelligence testing” appeared in Proceedings of the National Academy of Sciences in 2011. The meta-analysis portion included a 1978 paper by Stephen Breuning, a child psychologist who was the subject of 1987 report from the National Institute of Mental Health that found he “knowingly, willfully, and repeatedly” engaged in research misconduct and fabricated results in 10 NIMH funded articles.

As we reported earlier this year, six of Breuning’s papers have been retracted, including one last December. That article, published in 1978 in the Journal of School Psychology, found record albums, sporting event tickets, portable radios, and other incentives boosted scores on IQ tests.

Genentech authors flip PNAS study from corrected to retracted following Retraction Watch coverage

The authors of a 2006 paper have retracted their article following an extensive correction in January – and a Retraction Watch story noting the correction missed at least one additional issue with the work.

Death-receptor activation halts clathrin-dependent endocytosis,” published in July 2006 in Proceedings of the National Academy of Sciences, has been cited 99 times, according to Clarivate’s Web of Science. Most of the authors were affiliated with the biotech company Genentech. 

As we previously reported, commenters on PubPeer raised issues about possible image duplications, spurring the authors to review the work. The January correction addressed about two dozen instances of image splicing and duplication in five of the paper’s figures. The notice stated the authors repeated the experiments for a manuscript posted on bioRxiv in October 2024. “The new data confirms the original results, reaffirming the experimental conclusions,” the authors wrote in the correction notice.

Elsevier removes journal from Scopus after Retraction Watch inquiry

Elsevier has removed a journal from its Scopus database after Retraction Watch inquired about its review process for the journal, whose editorial board lists fake names and digital fingerprint shows other red flags.

Scientific sleuth Anna Abalkina uncovered several issues with Science of Law, which she details in a post published today. Besides editors and editorial board members who cannot be verified and don’t seem to exist, the journal’s history doesn’t match its publication record, early articles show signs of fabrication, and its publisher data in Scopus doesn’t match that in Crossref. Despite this, Scopus added the journal to its index last year. 

To understand how these problems could have evaded reviewers at Scopus, we asked Elsevier if Scopus staff verifies editorial board members when vetting journals, and if they assess the quality and validity of articles in journals before adding them to the index.

How do retractions impact researchers’ career paths and collaborations?

About 46% of authors leave their publishing careers around the time of a retraction, a new study has found.
SA Memon et al/Nat Hum Behav 2025

Several studies have tackled the issue of what effect a retracted paper has on a scientist’s reputation and publication record. The answer is, by and large, it depends: The contribution the researcher made on the paper, their career stage, the field of study and the reason for the retraction all play a role.

Three researchers from New York University’s campus in Abu Dhabi wanted to  better understand how a retraction affects a scientist’s career trajectory and future collaborations. Using the Retraction Watch Database, they looked at papers retracted between 1990 and 2015, and merged that data with Microsoft Academic Graph to generate information on researchers’ pre- and post-retraction publication patterns, as well as their collaboration networks. They also looked at Altmetric scores of retractions to factor in the attention a retraction got.

From that data, they extrapolated if and when researchers with retracted papers left scientific publishing, and looked for trends in researchers’ collaboration networks before and after the retraction.

Journal collected $400,000 from papers it later retracted

A Sage journal that holds the distinction of highest number of retracted articles in the Retraction Watch Database likely made in excess of $400,000 in revenue from those papers, by our calculations.

We reported in April that the Journal of Intelligent and Fuzzy Systems (JIFS) had retracted 1,561 articles as part of a cleanup operation on likely paper mill activity. The journal, which Sage acquired in November 2023 when it bought IOS Press, had previously retracted a batch of 49 articles in October 2021. That brings its retraction total up to 1,610.

Commenters on the April article pointed out the journal charges a fee for all accepted papers; separate fees apply for open access. We followed up on that with a few questions for Sage.

Former cancer researcher who sued university for discrimination hits 35 retractions

A cancer researcher who was once the subject of a misconduct investigation at an Illinois university more than 10 years ago has made his debut on the Retraction Watch Leaderboard with 35 retractions. 

Last month Oncogene, a Springer Nature title, retracted 15 articles by Jasti Rao, formerly of the University of Illinois College of Medicine at Peoria. A 2014 university investigation into his lab’s publications found manipulation and rotation of images that “‘show a disturbing pattern’ indicative that Rao acted intentionally or recklessly,” we previously reported.  Rao sued the university for wrongful termination but lost

More than 100 of Rao’s papers have comments on PubPeer, most originating from a user called Lotus azoricus. We now know that pseudonym belongs to sleuth Elisabeth Bik.

Why has it taken more than a year to correct a COVID-19 paper?

A correction to a clinical trial on a potential treatment for COVID-19 has taken more than a year — and counting — to get published. In the meantime, the article remains marked with an expression of concern that appeared in February 2024. 

The Lancet Regional Health–Americas published the study, a randomized clinical trial of the effect of metformin on hospitalization rates among COVID-19 patients, in December 2021. It has been cited 36 times, according to Clarivate’s Web of Science, 12 of those since the publication of the expression of concern.

In December 2023, the authors “identified small errors in the statistical analysis primary outcome,” corresponding author Edward Mills, a health research methods professor at McMaster University, in Hamilton, Ontario, told Retraction Watch. “We immediately re-ran the analysis and submitted as an erratum,” he said.

AI-Reddit study leader gets warning as ethics committee moves to ‘stricter review process’

University of Zurich

The university ethics committee that reviewed a controversial study that deployed AI-generated posts on a Reddit forum made recommendations the researchers did not heed, Retraction Watch has learned. 

The principal investigator on the study has received a formal warning, and the university’s ethics committees will implement a more rigorous review process for future studies, a university official said.

As we reported yesterday, researchers at the University of Zurich tested whether a large language model, or LLM, can persuade people to change their minds by posting messages on the Reddit subforum r/ChangeMyView (CMV). The moderators of the forum notified the subreddit about the study and their interactions with the researchers in a post published April 26
