The Soup Study Revisited

By: Rebecca McInroy

A classic study found that individuals eat less soup when they have a visual cue of how much they have eaten, thus demonstrating the power of external cues about eating. However, this research, done by Brian Wansink and his colleagues in 2005, was called into question by the lead researcher’s demonstrations of scientific misconduct.

A new research team, led by Alejandra Lopez, has replicated the study and published its findings in the Journal of Experimental Psychology: General. The team found that the main results hold up.

Yet, as Dr. Art Markman, and Dr. Bob Duke, discuss in this episode of Two Guys on Your Head, that the findings replicate is one thing, but how we interpret and use this information is another story altogether.
