Here’s an interesting excerpt from an article reviewing the new Heath brothers book Switch:
The book opens with a story from the Food & Brand Lab at Cornell University. Researchers set up at a movie theater and gave movie goers a free soft drink and bucket of popcorn—in exchange for them answering some questions about the concession stand at the end of the movie. Some of the moviegoers got a medium-size bucket of popcorn, and others got a huge tub. But here’s the kicker—both groups were given five-day-old popcorn that was so stale it squeaked. The questions at the concession stand were just a ruse—food researchers were studying how portion size influences eating.
And does it ever. People given the big tub ate 53% more of the practically inedible stuff than people given the medium bucket.
I’m pretty sure they could have carried out the same experiment at Okenshields using the regular food and different sized plates.
