Today comes one of the toughest blows in Dr Wansink's public fall from grace: the Journal of the American Medical Association has announced that it has retracted all six of the papers he published on how the size of a bowl affects how much we eat.
Brian Wansink, the Cornell nutrition researcher who was world-renowned for his massively popular, commonsense-style dieting studies before ultimately going down in flames in a beefy statistics scandal, has now resigned-with a considerably slimmer publication record. The news and stories that matter, delivered weekday mornings. Another, with the title "Bad popcorn in big buckets", similarly warned about the perils of presenting food in big quantities, according to Vox. He has appeared in multiple news outlets, including CNN.
Scrutiny of Wansink's work began after a 2016 blog post in which he recounted giving a data set to a graduate student and telling her there's "got to be something here we can salvage". At this time, it is appropriate to convey the results of Cornell's extensive review. According to that paper, retraction notices multiplied tenfold in the previous decade, while the actual number of published papers increased by only 44%.

In correspondence between 2008 and 2016, the renowned Cornell scientist and his team discussed and even joked about exhaustively mining datasets for impressive-looking results.
The blogged confession led to several other researchers sifting through Wansink's studies and stats.
"I stand by and am immensely proud of the work done here at the Lab", Wansink told BuzzFeed.
The JAMA network of journals retracted the papers Wednesday, saying the research couldn't be verified.More news: Electric Audi E-tron unveiled
Cornell University was urged to conduct an independent review of the research.
'Cornell University has notified JAMA that based on its investigation they are unable to provide assurances regarding the scientific validity of the six studies, ' Dr Bauchner wrote. "Their response states: 'We regret that, because we do not have access to the original data, we can not 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, JAMA Internal Medicine, and JAMA Pediatrics are hereby retracted". That warning culminated Wednesday in the journal retracting all of Wansink's articles it had previously published. Moreover, many researchers see the dubious approach as fueling a crisis in social sciences in which findings from key studies-like Wansink's-are not reproducible by other researchers, calling into question their original validity.
Wansink said that he did not keep some of the original surveys and sheets that were used in his research. That is, once we combined all the data into spreadsheets, we tossed the pencil and paper versions. Wansink says in a statement Friday his work had some statistical mistakes and other issues, but that he never intentionally misreported data.More news: Jurgen Klopp told 29-year-old’s form ‘big bonus’ for Liverpool FC
