Researchers from the psychology department at Yale University hung out in a handful of fast-food eateries (McDonald's, Burger King, Au Bon Pain and Starbucks) keeping an eye on customers' behavior. Of 4,311 people they observed, only six looked at the nutrition information provided by the restaurant, whether it appeared on a poster, in a pamphlet or on a special touch-screen computer.
