Campus Files: "Food Science?" – Detailed Summary

Introduction In the episode titled "Food Science?" released on April 23, 2025, Campus Files delves into the meteoric rise and dramatic fall of Brian Wansink, a prominent social scientist from Cornell University. Hosted by Margo Gray and produced by Audacy, the episode explores the complexities behind Wansink's acclaimed research on eating behaviors, the ensuing scientific misconduct scandal, and its broader implications for academic research integrity.

Brian Wansink's Rise to Prominence Brian Wansink became a household name in 2016 due to his innovative and widely publicized research on eating behaviors. As the head of the Cornell Food and Brand Lab, his studies attracted significant media attention and corporate interest.

• Scientific Contributions: Wansink's work, such as the influential study on “bottomless soup bowls,” demonstrated how subtle environmental changes could influence eating habits. As Margo Gray explains, “People with the self-refilling bowls ate significantly more, supporting the idea that the more food you see, the more you’ll eat” (04:23).

• Media and Policy Influence: Wansink's research extended beyond academia, impacting public policy and consumer behavior. His role as the executive director of the USDA's Center for Nutrition Policy and Promotion from 2007 to 2009 allowed him to influence the Dietary Guidelines for Americans (05:41).

The Blog Post Admission and Initial Scrutiny In late 2016, Wansink authored a blog post praising a grad student who transformed a "failed experiment" into five publishable papers. However, this post inadvertently exposed methodological flaws in his research approach.

• Questionable Research Practices: The blog revealed that Wansink encouraged researchers to manipulate data post-hoc to produce publishable results, bypassing the traditional hypothesis-driven methodology. Margo Gray notes, “Brian had in effect admitted to the very kind of scientific malpractice they [the data thugs] were fighting against” (09:54).

The Data Thugs Investigation In response to Wansink's admission, James Heathers and Nick Brown, known collectively as the "data thugs," began a rigorous analysis of Wansink's published work.

• Identifying Fraudulent Data: The data thugs discovered blatant inconsistencies and instances of self-plagiarism in Wansink's papers. Nick Brown explains, “We pulled some of his papers and found that some of the numbers... couldn't possibly be right” (15:14).

• Reproducibility Crisis Context: Their investigation coincided with the broader reproducibility crisis in science, where many studies across various fields failed to be replicated. James Heathers contextualizes, “This very famous, well-regarded guy had basically written a blog post about how he abused the research process” (14:07).

Stephanie Lee's Investigative Reporting Stephanie Lee, a science reporter at BuzzFeed News, played a crucial role in uncovering the depth of Wansink's misconduct.

• Pursuing Hidden Evidence: Lee sought access to internal emails and records, navigating around Cornell's private status by filing records requests at collaborating public institutions. She discovered that Wansink’s lab prioritized flashy, publishable results over scientific integrity. As she states, “There was overt discussion of... gross statistical manipulation” (20:58).

• Impactful Findings: Lee's tenacity led to the publication of 14 articles, bringing widespread attention to the issues within Wansink's research and sparking public and academic outrage.

Cornell University's Response and Investigation Faced with mounting evidence and public pressure, Cornell University initiated an internal investigation into Wansink's practices.

• Initial Attempts at Resolution: The data thugs first attempted to address their concerns privately, but communication with Wansink and Cornell stalled, prompting them to go public with their findings.

• Final Investigation Outcomes: In September 2018, Cornell concluded that Wansink had committed academic misconduct, including data falsification and inappropriate research practices. Nick Brown reads from the final report: “Professor Wansink committed academic misconduct under our policy” (22:38).

• Consequences for Wansink: Following the investigation, Wansink was removed from all research and teaching duties at Cornell and resigned from the university in June 2019 (22:55).

Implications for Academia and Scientific Research The Wansink scandal highlighted systemic issues within the academic research environment, particularly the pressures to publish prolifically and attract funding.

• Incentive Structures: Stephanie Lee points out, “the behavior that gets rewarded in academia is to publish a lot of research... a general focus on quantity over quality” (23:15), which can lead researchers to compromise on integrity.

• Broader Distrust in Science: James Heathers discusses the long-term repercussions, stating, “Part of the collective distrust in science now is built out of entirely legitimate stories that describe scientists behaving in an untrustworthy fashion” (24:40).

• Call for Reform: The episode underscores the need for reform in academic incentives and stronger safeguards against research misconduct to restore trust in scientific findings.
