The Supermarket: Prime Real Estate," Marion Nestle points out that "supermarket retailers know more than you could possibly imagine about how to push your ‘buy' button." She claims that supermarket companies control people to buy goods by using some surprised strategies. One of the evidence comes from Vance Packard's book The Hidden Persuaders that corporations were hiring social scientists to study unconscious human emotions to help companies manipulate people into buying products. Packard also talked about merchants use beautiful and interesting packaging to appeal customers, especially children customers.

People usually think food corporations only focus on developing their products, so before reading Nestle's essay, most readers would not be able to know that food companies also study in other fields other than food field.
