With Thanksgiving coming up, you want your guests to enjoy their food. However, an option to prevent overeating might be a change in the china rather than meal options. Recent research by Professors Brian Wansink and Koert van Ittersum explored how a well established optical illusion leads us to make inaccurate estimates of serving size, depending on what size plate they are presented on. The Delboeuf illusion has long been known to cause us to misjudge the size of identical circles when they are surrounded by larger circles of varying sizes. The more “white space” around the circle, the smaller it appears. We all learned this in school, but it never hurts to be reminded, right?
Black circles are exactly the same size
