Brian Wansink, the Cornell Professor Known for His Fun Food Research, Retires Amid Scandal

Accused of misconduct, he stands by the integrity of his work.

Brian Wansink, the celebrated Cornell University behavioral scientist whose studies have come under increasing scrutiny because of alleged problems with data and methodology, has told Cornell he intends to retire. He gave notice, in a letter he shared with Mother Jones, one day after the Journal of the American Medical Association (JAMA) retracted six articles based on his research. 

In a just-released statement, Cornell said that its internal investigation “found that Professor Wansink committed academic misconduct in his research and scholarship, including misreporting of research data, problematic statistical techniques, failure to properly document and preserve research results, and inappropriate authorship.” The statement went on to say that Wansink “has been removed from all teaching and research. Instead, he will be obligated to spend his time cooperating with the university in its ongoing review of his prior research.”

The subject of a 2015 profile I wrote for Mother Jones magazine, Wansink became a media darling thanks to his relatable and fun-to-talk-about studies pertaining to food and human behavior. Among his findings, for example, were that bigger plates lead to bigger servings of food and that people who sit closer to an all-you-can-eat buffet tend to eat more than those who dine farther away.

The criticism of Wansink’s work began in January 2017, when a team of researchers turned up more than 150 errors in four of Wansink’s studies. Wansink defended his work, arguing that social science isn’t as “definitive” as hard science. “These sorts of studies are either first steps, or sometimes they’re real world demonstrations of existing lab findings,” he told the scientific integrity watchdog Retraction Watch.  

In April 2017, Cornell’s initial investigation into Wansink’s work found mistakes but no ethical problems or misconduct. Yet the criticism kept coming. A Buzzfeed investigation this past February found more problems with his data analysis. Yesterday, in a notice that accompanied the retraction of his articles, JAMA reported that Cornell had informed the journal editors, “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.” 

Despite the mounting criticism, Wansink, 58, continues to stand by his work. In an email to his lab colleagues that he shared with Mother Jones yesterday, he wrote, “I’m very proud of all of these papers and all of the work we’ve done together.”

His retirement will take effect next June.

MORE HARD-HITTING JOURNALISM

In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones, a special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
