Larger portions of food cause people to JUN 28 2006
Larger portions of food cause people to eat more. Anyone who has eaten at Chili's and observed the girth of their clientele already knows this. Related: I remember seeing some research that showed as the size of an HTML textarea increases, the more words people write in it. (via mr)
Update: A self-refilling soup bowl experiment suggests that "visual cues of portion size may influence intake". (thx, justin) Also, adding lanes to heavily traveled roadways increases traffic; that is, supply increases demand.
