Second retraction for psychologist reveals clues about culprit behind misconduct

with 2 comments

A social psychologist has retracted a second paper that contains “fabricated or manipulated data.”

The first retraction for William Hart at the University of Alabama — also due to data manipulation — appeared earlier this year. The notice raised some questions over authorship: Hart was the sole author, but he blamed the retraction on a graduate student who supplied the problematic data. The questions continued when Hart’s colleagues posted blogs about the problems that occurred in Hart’s lab, using a pseudonym to describe the student, who apparently admitted to fabricating data.

Looking at the author list of the newest retraction, by process of elimination, we now have a lead on the identity of the graduate student who allegedly took responsibility for the misconduct.

Monkey business? 2002 Cognition paper retracted as prominent psychologist Marc Hauser takes leave from Harvard

with 16 comments

Marc Hauser, a prominent Harvard psychology researcher and author, will be taking a leave of absence from the university following “a lengthy internal investigation found evidence of scientific misconduct in his laboratory” that has led to the retraction of one of his papers, according to The Boston Globe.

The retraction, of a 2002 paper in Cognition, reads, in part: “An internal examination at Harvard University . . . found that the data do not support the reported findings. We therefore are retracting this article,” the Globe reports.  It also includes the sentence “MH accepts responsibility for the error.”

The retraction notice does not yet appear anywhere on the journal’s site, where the PDF version of the study is still available, nor on the Medline abstract. Its circumstances appear to be atypical, according to the Globe: Read the rest of this entry »
