What Caught Our Attention: Brian Wansink, the beleaguered food marketing researcher at Cornell University, has already earned a retraction — two, if you count the fact that a retracted and replaced article was then retracted — and a correction from JAMA journals. Today, JAMA and two of its journals issued Expressions of Concern for six articles by Wansink and colleagues — all of those by him that have not yet been retracted. One of those paper has been cited more than 100 times.
JAMA is also asking Cornell to “conduct an independent evaluation of the articles to determine whether the results are valid or not.”
Wansink has now had a total of seven papers retracted. His troubles began in late 2016 when he published a blog post that many read as evidence he had engaged in p-hacking. That led to scrutiny by a group of four researchers, which was followed by investigations by Cornell and journals.
Update, 1930 UTC, 4/13/18: Howard Bauchner, editor in chief of JAMA and the JAMA Network journals, tells Retraction Watch:
[O]ne of the most important functions of a medical journal is to ensure that the scientific literature is correct. Given the large number of retractions of articles with Dr. Wansink as an author there is uncertainty that the results of his publications are valid. Indeed we issued a notice of concern because of this uncertainty, and hope that with proper validation of the findings in these studies the notice of concern can be removed.

We are issuing a Notice of Expression of Concern for these 3 articles (1-3) published in JAMA Internal Medicine and all articles published in JAMA and the JAMA Network specialty journals(4-6) that include Brian Wansink, PhD, as an author. These Notices of Expression of Concern are to alert the scientific community to the ongoing concerns about the validity of these publications. We have communicated with Cornell University and Dr Wansink, and we have requested that Cornell University conduct an independent evaluation of the articles to determine whether the results are valid or not.
