Choice is an illusion. Or so it seems. In a mixture of psychology, neurology, and just plain observation, marketers understand the average shopper in ways that might surprise you and they make every effort to capitalize on that knowledge.
For example, research has shown that the first turn shoppers make is a right one. As a result, retailers put their newer, more exciting products in the front right of their stores. Retailers invest in extra advertising for the front of the store and consumers are more sensitive to external cues earlier in their shopping experience. Coupons given at the store entrance see more results than those given inside the store. One Harvard study shows that a coupon can actually increase the amount a customer is willing to spend.
Marketers know all of these things and are learning more about shopping habits every day. To find out more about this subject, check out this infographic presented by BestPsychologyDegrees.
