In a study that will be published in the Journal of Consumer Research, college students were given two different menus. One had French fries, chicken nuggets, and a baked potato, and the other had the same items plus a salad. The french fries, which were seen as the least healthy item, were three times as popular with students ordering from the menu that had salad as with the other group. “When you consider the healthy option, you say, well, I could have that option,” said researcher Keith Wilcox. “That lowers your guard, leading to self-indulgent behavior.” [NY Times]
