“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 »

“Invalid data” prompt retraction of another paper from psychologist Sanna

with 9 comments

The journal Group Dynamics: Theory, Research, and Practice is retracting a 2003 paper by psychologist Lawrence Sanna, who appears to have been fabricating his data. Sanna’s work, Retraction Watch readers may recall, came under the scrutiny of Uri Simonsohn, who also investigated Dirk Smeesters’ research.

Here’s the notice, which offers an impressive amount of back story as these things go: Read the rest of this entry »

Psychological Science retracts a Sanna paper, citing lawyers, COPE…and Retraction Watch

with 8 comments

In April 2011, we praised Psychological Science for its handling of a retraction. At the time, we went as far as to call the retraction notice a “model” of transparency for other journals to follow.

Well, they evidently took that compliment seriously, according to a new retraction notice for a paper by Lawrence Sanna. Sanna left Michigan under a cloud a few months ago after another scientist found his data statistically implausible, as Ed Yong reported in Nature.

The newly retracted paper, “Construing collective concerns: Increasing cooperation by broadening construals in social dilemmas,” was published in 2009 while Sanna was still at the University of North Carolina-Chapel Hill. Here’s a sample from the abstract: Read the rest of this entry »

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

with 11 comments

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: Read the rest of this entry »
