Following questions about the veracity of multiple papers by his former employer, high-profile social psychologist Jens Förster has agreed to retract two papers as part of a deal with the German Society for Psychology (DGPs).
Last year, Förster had a paper retracted at the request of his former employer, the University of Amsterdam (UvA). In May, an investigation commissioned by UvA found that many of his experiments looked “too good to be true,” and eight papers showed strong signs of “low veracity.”
Just two of those papers are acknowledged in the settlement of a case by the DGPs against Förster, who currently works at Ruhr University Bochum. Here’s a translation of a notice from the DGPs from One Hour Translation:
We’ve learned about two more retractions we missed for Diederick Stapel, the Dutch social psychology researcher who has now racked up a total of 57 retractions by our count.
Both retractions were issued after a committee released a report which established fraud in dozens of papers co-authored by Stapel.
Stapel is still #4 on our leaderboard.
This week’s issue of Science includes a retraction of a highly cited paper about manipulating the current in a string of molecules with a magnet, after an investigation by the co-authors revealed “inappropriate data handling” by the first author.
According to the note, the co-authors’ suspicions arose when they tried to follow-up on the data. Following a “thorough investigation,” they concluded that first author Rabindra N. Mahato had handled the data in such a way that they could no longer trust the conclusions. In the end, Mahato agreed to the retraction.
The National Ombudsman of The Netherlands has criticized some aspects of an investigation by Utrecht University that found a researcher had committed “a violation of academic integrity.”
Specifically, the Ombudsman found the investigation — which we covered last year — did not adequately involve the affected researcher, Pankaj Dhonukshe, and therefore violated rules of “fair play.” Dhonukshe expressed relief in a statement he emailed to us about the ruling: Read the rest of this entry »
The “fraudulent” Social Cognition article found, according to its abstract, that the more positively you perceive yourself, the less you need to compare yourself to other people. Conversely, negative thoughts were linked to more comparison to others. As an article in the New York Times points out, where Stapel’s faulty studies often succeeded is in telling us what we want to believe about the world.
Here’s the retraction note for the article:
The European Ophthalmic Review has retracted a 2014 article about the macular degeneration drug aflibercept without any explanation.
Here’s the retraction notice, such as it is:
A new group of experts is suggesting there’s something fishy in the body of work of social psychologist Jens Förster.
The University of Amsterdam, Förster’s former employer, commissioned three statistical experts to examine his publication record, looking for signs that the data are not authentic.
Well, they found some signs:
A 2014 Cancer Cell paper became the subject of an erratum in January 2015, shortly after PubPeer members began criticizing the data. However, many issues brought up by commenters weren’t addressed in the correction notice, including a figure that might be two experiments spliced together to look like one.
The paper, led by Guido Franzoso at Imperial College London, claims that a new cancer drug called DTP3 kills myeloma cells “without causing any toxic side effects,” according to a press release from the school. Guido Franzoso is the founder of Kesios Therapeutics, a drug company which is set to begin clinical trials on DTP3.
The correction indicates that Western blots were cropped badly, which omitted several panels discussed in the text, while an “extra time point” was included accidentally. An antibody was also omitted from the description of the procedure.
PubPeer commenters have noticed additional issues, such as a criticism of figure 3D, which were not included or changed in this correction.
The Free University of Amsterdam found Peter Nijkamp, one of the nation’s leading economists who has lost several papers for self-plagiarism, has been found guilty of “questionable research practices,” according to the newly released results of an investigation.
Nijkamp has published a strongly worded criticism of the report (at least according to Google Translate, since his writing is in Dutch).
According to independent student publication Ad Valvas, the commission, led by Jaap Zwemmer, a professor emeritus at the University of Amsterdam, found Nijkamp was guilty of “questionable research practices.” University rector Frank van der Duyn Schouten, on the other hand, said in an official statement that there was “insufficient basis” to claim questionable research practices for each article.
