We missed one: Make that two retractions for Dirk Smeesters

with one comment

Earlier today, we reported on what we thought was the first retraction to appear for Dirk Smeesters, who we noted was “the former Erasmus University social psychology professor investigated for serious irregularities in his work.” It turns out, however, as a Retraction Watch tipster told us, that another retraction had already been published.

The notice appeared in the August 2012 issue of the Journal of Consumer Research: Read the rest of this entry »

Retraction appears for paper by social psychologist Dirk Smeesters

with one comment

A paper by Dirk Smeesters — the former Erasmus University social psychology professor investigated for serious irregularities in his work — has been retracted.

The study, “Visual perspective influences the use of metacognitive information in temporal comparisons,” appeared in the Journal of Personality and Social Psychology earlier this year. Here’s the notice, which doesn’t quite say “fraud”: Read the rest of this entry »

Final report in Smeesters case serves up seven retractions

with one comment

smeestersErasmus University in Rotterdam has issued its final report on psychologist Dirk Smeesters, concluding that the former Erasmus faculty member had committed research misconduct in a total of seven papers. Three of those articles already have been retracted in the case, as we reported in December 2012.

The committee investigation is in fact a follow-up inquiry — thus its name, the Smeesters Follow-Up Investigation Committee — prompted by concerns that an initial probe was incomplete. According to the report, the four-member panel conducted an “in-depth analysis” of every paper Smeesters, who left the university’s Rotterdam School of Management in July 2012, was “actively” involved in. That turned out to be 22 articles (not including three others already retracted).

The final report is worth reading, presented here as a pdf. The four articles are: Read the rest of this entry »

“Fraud committed by any social psychologist diminishes all social psychologists”: New Sanna, Smeesters retractions

with 33 comments

jespThree new retractions — two of papers by Lawrence Sanna and one of work by Dirk Smeesters —  have appeared in the Journal of Experimental Social Psychology. The retractions come along with a hard-hitting piece by the journal’s editor.

In a tough soul-searching editorial called “On Fraud, Deceit, and Ethics” (unfortunately only available behind a paywall), journal editor in chief Joel Cooper writes that “Fraud committed by any social psychologist diminishes all social psychologists.” He continues: Read the rest of this entry »

Is post-hoc statistical analysis the new fraud detection tool? A new review looks at fraudster Reuben’s work

with 6 comments

In the beginning, there was Scott Reuben.

Well, not quite. Reuben, a Massachusetts anesthesiologist who fabricated data and briefly topped our list of most-retracted authors, didn’t invent research fraud, although he did spend six months in federal prison for his crimes. But his case was in no small measure responsible for the birth of this blog, and, well, the rest of human history that followed.

Although Reuben’s retractions are behind him now — his count ends at 22 — and other scientists, including two anesthesiologists, Joachim Boldt and Yoshitaka Fujii, have or likely soon will dramatically eclipsed his mark, a new paper has revisited his publications with an eye toward seeing if they could identify statistical evidence of data manipulation. It’s the same  kind of effort that Ed Yong highlighted as noteworthy about the Dirk Smeesters case, which we covered yesterday and which involved an anonymous statistically inclined whistleblower.

Before we get to whether there was evidence of such manipulation Read the rest of this entry »

Analysis casts doubt on bone researcher’s body of work

with 3 comments

19-coverA new analysis of more than 30 clinical trials co-authored by a bone researcher based in Japan is casting doubt on the legitimacy of the findings.

Yoshihiro Sato, based at Mitate Hospital, has already retracted 12 papers, for reasons ranging from data problems, to including co-authors without their consent, to self-plagiarism. Most of these retracted papers are included in the analysis in the journal Neurology, which concluded that Sato’s 33 randomized clinical trials exhibited patterns that suggest systematic problems with the results.

Other researchers have used similar approaches to analyze a researcher’s body of work — notably, when John Carlisle applied statistical tools to uncover problems in the research of notorious fraudster Yoshitaka Fujii, and Uri Simonsohn, who sniffed out problems with the work of social psychologist  Dirk Smeesters.

Author Mark Bolland of the University of Auckland told us he was surprised by his findings: Read the rest of this entry »

Psychology retractions have quadrupled since 1989: study

with 6 comments

Marc Hauser. Dirk Smeesters. Diederik Stapel.

Psychology has been home to some of the most infamous cases of fraud in recent years, and while it’s just a few bad apples who are spoiling the bunch, the field itself has seen an overall increase in retractions, according to a new paper by Jürgen Margraf appearing in Psychologische Rundschau and titled “Zur Lage der Psychologie.”

That increase, Margraf found, is not entirely due to its most well-known fraudsters. Here’s the relevant figure:
