Three more retractions for Diederik Stapel

We apologize for what must seem like a constant drip, drip, drip, but we have three more retractions from Diederik Stapel to report, all from the European Journal of Social Psychology.

The first, in order of publication date, involves a 2006 paper by Stapel and co-author Camille Johnson — whose name has appeared on several other of Stapel’s retracted papers — titled “When nothing compares to me: How defensive motivations and similarity shape social comparison effects.”

The notice reads: Continue reading Three more retractions for Diederik Stapel

University of Michigan psychologist resigns following concerns by statistical sleuth Simonsohn: Nature

A second psychology researcher has resigned after statistical scrutiny of his papers by another psychologist revealed data that was too good to be true.

Ed Yong, writing in Nature, reports that Lawrence Sanna, most recently of the University of Michigan, left his post at the end of May. That was several months after Uri Simonsohn, a University of Pennsylvania psychology researcher, presented Sanna, his co-authors, and Sanna’s former institution, the University of North Carolina, Chapel Hill, with evidence of “odd statistical patterns.”

Simonsohn is the researcher who also forced an investigation into the work of Dirk Smeesters, who resigned last month. Last week, Yong reported that Simonsohn had uncovered another case that hadn’t been made official yet.

According to today’s story, Sanna has asked the editor of the Journal of Experimental Social Psychology — which is also retracting one of Smeesters’ papers — to retract three papers published from 2009 to 2011. These are the three he seems to have published there during that time: Continue reading University of Michigan psychologist resigns following concerns by statistical sleuth Simonsohn: Nature

Withdraw that emotion: Psych journal retracts two Stapel papers on mood

Two more papers from Dutch fraudster Diederik Stapel have been retracted. Both appeared in the journal Psychological Science in 2008, with the same, evidently unwitting co-author, Kirsten Ruys, of Tilburg University.

Following investigation, Erasmus social psychology professor retracts two studies, resigns

Dirk Smeesters

The social psychology community, already rocked last year by the Diederik Stapel scandal, now has another set of allegations to dissect. Dirk Smeesters, a professor of consumer behavior and society at the Rotterdam School of Management, part of Erasmus University, has resigned amid serious questions about his work.

According to an Erasmus press release, a scientific integrity committee found that the results in two of Smeesters’ papers were statistically highly unlikely. Smeesters could not produce the raw data behind the findings, and told the committee that he cherry-picked the data to produce a statistically significant result. Those two papers are being retracted, and the university accepted Smeesters’ resignation on June 21.

The release also takes pains to say that the university has no reason to doubt the work of his co-authors. You can read the complete report in Dutch, with Smeesters’ co-authors’ names blacked out, in an NRC Handelsblad story.

Erasmus tells Retraction Watch that these are the two papers being retracted: Continue reading Following investigation, Erasmus social psychology professor retracts two studies, resigns

Psychologists take a gamble on using data about risky behavior, and are forced to retract a paper

When the first sentence of a science paper reads like this, you might think you’re in for quite a ride:

Jumping out of an airplane may seem like a crazy and scary thing to do, but for a skydiver it is a fun and exciting experience.

Unfortunately for the authors of an earlier version of that paper comparing gamblers and skydivers, published in 2011 in the Scandinavian Journal of Psychology, the ride was short-lived, according to a retraction notice just published: Continue reading Psychologists take a gamble on using data about risky behavior, and are forced to retract a paper

Brit psych journal retracts Stapel paper on the paradox of failure

In 2011, Diederik Stapel, a Dutch researcher who at the time was a shining star in the world of social psychology, published an article in the British Journal of Social Psychology with the counter-intuitive claim that failure can sometimes be more emotionally gratifying than success.

We’re guessing this isn’t one of those times. As readers of this blog well know, Stapel has admitted to fabricating loads of data. The BJSP has now retracted the article.

Here’s the notice for the paper, which has yet to be cited, according to Thomson Scientific’s Web of Knowledge: Continue reading Brit psych journal retracts Stapel paper on the paradox of failure

Journal retracts two Stapel papers, on salesmen and on women who change their names when they marry

Here are the notices, which appear together: Continue reading Journal retracts two Stapel papers, on salesmen and on women who change their names when they marry

Science expresses “concern” about Stapel paper

A day after Tilburg University released its preliminary report on psychologist Diederik Stapel, Science has issued an “expression of concern” about one of his papers.

The 2011 article, titled  “Coping with Chaos: How Disordered Contexts Promote Stereotyping and Discrimination,” was written by Stapel and Siegwart Lindenberg, a Tilburg colleague with an appointment at the University of Groningen.

Here’s the notice, signed by Science editor Bruce Alberts: Continue reading Science expresses “concern” about Stapel paper

You will not plagiarise. You will not plagiarise. You will not…but if you do, hypnosis journal will retract

The International Journal of Clinical and Experimental Hypnosis is retracting a 2009 article by researchers who seem to have stolen material from a graduate student — and who are fond of studying memories from past lives in other work.

The article, “Norms for the Korean Version of the Harvard Group Scale of Hypnotic Susceptibility, Form A,” was written by Yun Joo Kim and Young Don Pyun, of the eponymous Pyun Neuropsychiatric Clinic, in Seoul, South Korea. The Pyun Clinic specializes in “hypnotherapy for psychiatric illness,” according to its website.

Here’s the retraction notice: Continue reading You will not plagiarise. You will not plagiarise. You will not…but if you do, hypnosis journal will retract
