The social facilitation of eating or the facilitation of social eating?

Abstract

People eat more when they eat in groups. Various explanations have been offered for this "social facilitation" of eating. We consider these explanations and find most of them wanting, especially insofar as they do not take into account the increased per capita provision of food when people eat together. We suggest that people often prefer to eat in groups precisely because it offers them an opportunity to overindulge.
