Why does shopping science matter? Studying why and how people shop scientifically matters because businesses use that information to influence consumers to buy, and buy more. So, it is important for consumers to know what businesses know about them. The following quiz is based on findings reported in environmental psychologist and business consultant Paco Underhill’s bestselling book, “Why We Buy: The Science of Shopping.”

1. True or False:  People (especially women) brushed from behind buy more.


2. True or False: Shoppers tend to move to the left upon entering a store.


3. True or False: Where merchandise is placed on store shelves matters relatively little because price and consumer interest largely determine what gets purchased.


4. Why do supermarket designers often place milk toward the back of the store?


5. True or False: It is easier for businesses to sell to men than to women shoppers.
