On May 8, 2018, notices of Expression of Concern1-3 were published regarding articles published in JAMA Internal Medicine,4-6JAMA,7 and the JAMA Pediatrics8,9 that included Brian Wansink, PhD, as author. At that time, Cornell University was contacted and was requested to conduct an independent evaluation of the articles to determine whether the results are valid.
Cornell University has notified JAMA that based on their investigation they are unable to provide assurances regarding the scientific validity of the 6 studies. Their response states: “We regret that, because we do not have access to the original data, we cannot assure you that the results of the studies are valid.” Therefore, the 6 articles reporting the results of these studies that were published in JAMA Internal Medicine,4-6JAMA,7 and JAMA Pediatrics8,9 are hereby retracted.
