Cornell says Brian Wansink “committed academic misconduct,” and is leaving the university. He’s a cautionary tale in bad incentives in science. Thirteen of Wansink’s studies have now been retracted, including the six pulled from JAMA Wednesday. ...To date, 13 of his papers have been retracted. And that’s stunning given that Wansink was so highly cited and his body of work was so influential. Wansink also collected government grants, helped shape the marketing practices at food companies, and worked with the White House to influence food policy in this country.
