Why traditional statistics are often “counterproductive to research the human sciences”

Andrew Gelman

Doing research is hard. Getting statistically significant results is hard. Making sure the results you obtain reflect reality is even harder. In this week’s Science, Eric Loken at the University of Connecticut and Andrew Gelman at Columbia University debunk some common myths about the use of statistics in research — and argue that, in many cases, the use of traditional statistics does more harm than good in human sciences research.

Elsevier to retract six more papers by computer scientist, citing duplication and fake reviews

Yesterday we reported that Elsevier journals had pulled three papers by a computer scientist with an impressive publication record. The publisher has since informed us that it plans to pull six more, again citing duplication and manipulation of the peer-review process.

Shahaboddin Shamshirband at the University of Malaya in Kuala Lumpur, Malaysia’s record will be down by a total of nine papers once the publisher issues the additional notices. We also found evidence that an additional paper was removed by a journal, but haven’t confirmed if that’s a retraction.

One of Shamshirband’s co-authors has objected to one of the retractions Elsevier has already issued for faked reviews, arguing the reviewers were PhD students without institutional email addresses. A spokesperson for Elsevier told us:

Computer scientist loses at least three papers, two for faked reviews

A computer scientist in Malaysia has lost two papers for faked peer reviews, and another for duplication. A fourth paper on which he is a co-author appears to have simply disappeared.

One retraction lays the blame for the fake reviewer on corresponding author Shahaboddin Shamshirband at the University of Malaya in Kuala Lumpur, Malaysia. According to the journal, Shamshirband — who has co-authored more than 200 papers and book chapters, despite receiving his PhD in 2014, according to his biography on Vitae — supplied a fake email for the reviewer during the submission process.

Here’s the retraction notice for that paper, issued by the journal Measurement:

Study about words’ effect on mood to be retracted after investigation finds evidence of data manipulation

A study examining whether the verb tense you use to describe a positive or negative experience influences your current mood will be retracted after a university investigation found the data had been manipulated.

By whom is the question — the notice cites an unnamed graduate student as the source of the manipulation, and says the only author, William Hart, was unaware of what had occurred.

We spoke with Hart, based at the University of Alabama, who declined to identify the student, nor say whether he or she was still working at the university. He did say the experience has been trying:

Cancer researcher logs 6 retractions, bringing total to 10

Anil Jaiswal

A journal has retracted six papers by a cancer researcher at the University of Maryland in Baltimore, bringing his total to 10.

The retractions cite an investigation by the university, and detail problems ranging from duplicated images, to tweaking an image to conceal particular bands, to including unreliable data.

Three of the papers had already been flagged by the journal with expressions of concern. The last author on all the papers is Anil Jaiswal, a professor in the pharmacology department. He has issued four previous retractions.

Bruce Jarrell, the Chief Academic and Research Officer and Senior Vice President at the University of Maryland, told us at least two more retractions are forthcoming:

Backlash prompts prominent nutrition researcher to reanalyze multiple papers

Brian Wansink

To Brian Wansink of Cornell University, a blog post he wrote in November, 2016, was a meant as a lesson in productivity: A graduate student who was willing to embrace every research opportunity submitted five papers within six months of arriving to his lab, while a postdoc who declined two chances to analyze a data set left after one year with a small fraction of the grad student’s publications.

But two months and nearly 50 comments on the post later, Wansink — known for so much high-profile nutrition research he’s been dubbed the “Sherlock Holmes of food” — has announced he’s now reanalyzing the data in the papers, and will correct any issues that arise. In the meantime, he had to decline requests to share his raw data, citing its proprietary nature.

As Wansink writes in the second addendum to the November blog post, “The Grad Student Who Never Said ‘No’:”

Journals pull two papers after blogger shares plagiarism suspicions

Journals have retracted two papers after they were flagged by a pseudonymous blogger, who suspected all had copied text from other sources.

What’s more, a third paper seems to have simply disappeared from the journal’s website, after the blogger, Neuroskeptic, alerted the journal to the text overlap.

Neuroskeptic became suspicious about the three unrelated papers – about food chemistry, heart disease, and the immune system and cancer – after scanning them with plagiarism software. After alerting the journals, two issued formal retractions for the papers – but neither specifies plagiarism as the reason.

The retractions were the result of a larger project, Neuroskeptic told us:

High-profile book on North Korea earns 52 corrections

The author of a high-profile book about the history of North Korea is issuing 52 corrections to the next edition, scheduled to appear this spring. The changes follow heavy criticism of the book, alleging it contained material not supported by the list of references.

Last month, author Charles Armstrong, a professor at Columbia University, announced on his website that he was issuing the changes after reviewing the book in detail, especially the footnotes. He writes:

Do you calculate if you should accept an invite to peer review? Please stop, say journal editors

Raphael Didham

Scientists are always pressed for time; still, Raphael Didham of the University Western Australia was surprised when he fell upon a group of early career scientists using a spreadsheet formula to calculate whether one was obligated to accept an invitation to review a paper, based on how many manuscripts he’d submitted for review. “I recall that sharp moment of clarity that you sometimes get when you look up from the keyboard and realise the world you (thought you) knew had changed forever,” Didham and his colleagues write in a recent editorial in Insect Conservation and Diversity. We spoke with Didham about how to convince scientists that peer reviewing is a benefit to their careers, not a burden.

Retraction Watch: You talk about the current problem of “zero-sum” reviewing. Could you define that in the context of the scientific peer review system? Continue reading Do you calculate if you should accept an invite to peer review? Please stop, say journal editors
