There is an interesting discussion going on at the Becker-Posner blog about obesity abatement. Richard Posner talks about the NY ordinance requiring that calorie counts of food be prominently labeled fast food restaurants: The significance of the New York City ordinance lies in its requiring that calorie numbers be printed next to the food items on menus and menu boards and in large type. The purpose is less to inform than to frighten. Psychologists have shown (what is anyway pretty obvious) that people respond more to information that is presented to them in a dramatic, memorable form than to information that is presented as an abstraction or is merely remembered rather than being pushed in one's face; that is the theory beyond requiring reckless drivers to watch videotapes of accidents and requiring cigarette ads to contain fearsome threats. It is one thing to know that a Big Mac has a lot of calories, and another thing to have the number emblazoned on the menu board, next to a mouth-watering picture. The warnings--for that is what the display of high calorie numbers amounts to--may create fear of high-calorie foods, not only in fast-food chains but generally. If so, and if as a result there is less obesity, there will be a reduction in medical expense and possibly a gain in happiness if, as one suspects, thin people are on average happier than fat people.
