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

University of Michigan psychologist resigns following concerns by statistical sleuth Simonsohn: Nature
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: Read the rest of this entry »
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: Read the rest of this entry »
