‘Please don’t be afraid to talk about your errors and to correct them.’

A “systematic error” in a mental health database has led to the retraction of a 2017 paper on how people with psychosis process facial expressions.

Joana Grave, a PhD student at the University of Aveiro, in Portugal, and her colleagues published their article, “The effects of perceptual load in processing emotional facial expression in psychotic disorders,” in Psychiatry Research, an Elsevier title.

According to the abstract of the paper:

‘In hindsight the mistake was quite stupid’: Authors retract paper on stroke

File this under “doing the right thing:” A group of stroke researchers in Germany have retracted a paper they published earlier this year after finding an error in their work shortly after publication that doomed the findings.

Julian Klingbeil, of the Department of Neurology at the University of Leipzig Medical Center, and his colleagues had been looking at how the location of lesions in the brain left behind by cerebral strokes were associated with the onset of depression after the attacks. According to the study, “Association of Lesion Location and Depressive Symptoms Poststroke”:

“The right decision”: Group retracts Nature Chemical Biology paper after finding a key error

Researchers in Australia have retracted a 2016 paper in Nature Chemical Biology after discovering a critical error in their research, bringing some closure to a gut-wrenching case for the scientists involved.

As we reported in January, Nicola Smith, the senior author of the article, titled “Orphan receptor ligand discovery by pickpocketing pharmacological neighbors,” described learning of the error as “the most horrific time” of her career.

Smith, then at the Victor Chang Cardiac Research Institute in Sydney (she’s now at the Orphan Receptor Laboratory at the University of New South Wales) told us that she briefly considered letting the flawed research — which has been cited 26 times, according to Clarivate Analytics’ Web of Science — go uncorrected.

After all, as one colleague told her, the subject of the studies was so arcane that

Why “good PhD students are worth gold!” A grad student finds an error

Researchers in the Netherlands have retracted and replaced a 2015 paper on attention after discovering a coding error that reversed their finding.

Initially titled “Effects of Transcranial Direct Current Stimulation over Left Dorsolateral pFC on the Attentional Blink Depend on Individual Baseline Performance,” the paper appeared in the Journal of Clinical Neuroscience and was written by Heleen A. Slagter, an associate professor of psychology at VU University in Amsterdam, and Raquel E. London, who is currently a post-doc at Ghent University. It has been cited 19 times, according to Clarivate Analytics’ Web of Science.

But while trying to replicate the findings, Slagter and a then-PhD student of hers, Leon Reteig, found a critical mistake in a statistical method first proposed in a 1986 paper. Slagter told us:

‘I thought I had messed up my experiment’: How a grad student discovered an error that might affect hundreds of papers

Earlier this month, we reported on how Susanne Stoll, a graduate student in the Department of Experimental Psychology at the University College London, discovered an error that toppled a highly-cited 2014 article — and which might affect hundreds of other papers in the field of perception.

We spoke with Stoll about the experience.

Retraction Watch (RW): What did it feel like to find such a significant error? Did you doubt yourself at first, and, if so when did you realize you’d found something both real and important?

‘I dropped the ball’: Magic bullet falls short of target

A sports medicine journal has retracted a widely circulated 2019 meta-analysis which purported to find that interval training was the “magic bullet” for weight loss, after the analysis proved to be riddled with holes.

The paper, “Is interval training the magic bullet for fat loss? A systematic review and meta-analysis comparing moderate-intensity continuous training with high-intensity interval training (HIIT),” was a collaboration by researchers in Brazil and James Steele, an exercise scientist at the Solent University School of Sport, Health and Social Sciences, in Southampton, England.

Steele has some cred when it comes to research integrity, and part of that cred comes from another retraction. He was part of a team of data sleuths who have called for the retraction of seven papers by Matheus Barbalho, a Brazilian exercise scientist.

The grad student who found a fatal error that may affect lots of papers

A team of researchers in England has retracted a 2014 paper after a graduate student affiliated with the group found a fatal error while trying to replicate parts of the work — and which might affect similar studies by other scientists, as well.

The article, “Perceptual load affects spatial tuning of neuronal populations in human early visual cortex,” was written by Benjamin de Haas, then of the Institute of Cognitive Neuroscience at the University College London, and his colleagues at UCL.

Doing the right thing: Alcoholism researchers retract six-week old paper after finding errors

Oh, those insufferably progressive Scandinavians, always doing the right thing.

A group of alcoholism researchers in Denmark has retracted a 2020 paper on gender and alcohol treatment after finding errors in their results. And they’ve set up a system to avoid similar problems in the future.

The paper, “Gender differences in alcohol treatment,” appeared in Alcohol & Alcoholism in July, with authors from the University of Southern Denmark in Odense. The paper found that:

“Honest errors happen in science:” JAMA journal retracts paper on antidepressants

A review of scores of studies on antidepressants has been retracted because it used an incorrect analysis.

The original paper, published in JAMA Psychiatry on February 19, 2020, looked at individual differences in patients taking antidepressants and concluded that there were significant differences beyond the placebo effect or the data’s statistical noise. The paper earned some attention, including a story on MedPage Today.

However, the analysis didn’t hold up to scrutiny. The retraction notice reads:

‘[A] disappointing situation’: Stem cell group retracts with ‘rectitude’ after error

A team of stem cell researchers at the University of Maryland has lost a 2020 paper after failing to correct an error that they’d caught prior to submission.

The paper, “Endothelial/mesenchymal stem cell crosstalk within bioprinted coculture,” appeared in Tissue Engineering Part A, a Mary Ann Liebert publication. The senior author of the article was John Fisher, who holds an endowed chair in bioengineering at Maryland and also is one of the journal’s co-editors.
