SSRN-Environmental Factors that Unknowingly Increase a Consumer's Food Intake and Consumption Volume by Brian Wansink

More on what as a finance professor familiar with behavioral finance and behavioral economics would call behavioral eating. The short version is that people's caloric consumption and overall food choices are not always rational. Indeed that are influenced by things such as size of plate and other factors that never enter into a "classical" or "rational" or "econ" decision.

SSRN-Environmental Factors that Unknowingly Increase a Consumer's Food Intake and Consumption Volume by Brian Wansink:

"Package size, plate shape, lighting, socializing, and variety are only a few of the environmental factors that can influence the consumption volume of food far more than most people realize. Although such environmental factors appear unrelated, they generally influence consumption volume by inhibiting consumption monitoring and by suggesting alternative consumption norms. For researchers, this review shows that redirecting our focus to the 'whys' or the psychological mechanisms behind consumption will raise the profile and impact of our research."
