Brian Wansink

Brian Wansink (born June 28, 1960) is an American former professor and researcher who worked in consumer behavior and marketing research. He was the executive director of the USDA's Center for Nutrition Policy and Promotion (CNPP) from 2007 to 2009 and held the John S. Dyson Endowed Chair in the Applied Economics and Management Department at Cornell University, where he directed the Cornell Food and Brand Lab.

Wansink's lab researched people's food choices and ways to improve those choices. Starting in 2017, problems with Wansink's papers and presentations were brought to wider public scrutiny. These problems included conclusions not supported by the data presented, data and figures duplicated across papers, questionable data (including impossible values), incorrect and inappropriate statistical analyses, and "p-hacking". On September 20, 2018, Cornell determined that Wansink had committed scientific misconduct and removed him from research and teaching activities; he resigned effective June 30, 2019.
