The Science of Shopping

The more time you spend with Paco's videos, though, the less scary they seem. After an hour or so, it's no longer clear whether simply by watching people shop-and analyzing their every move-you can learn how to control them. The shopper that emerges from the videos is not pliable or manipulable. The screen shows people filtering in and out of stores, petting and moving on, abandoning their merchandise because checkout lines are too long, or leaving a store empty-handed because they couldn't fit their stroller into the aisle between two shirt racks. Paco's shoppers are fickle and headstrong, and are quite unwilling to buy anything unless conditions are perfect-unless the belt is presented at exactly the right moment. His theories of the butt-brush and petting and the Decompression Zone and the Invariant Right seek not to make shoppers conform to the desires of sellers but to make sellers conform to the desires of shoppers. What Paco is teaching his clients is a kind of slavish devotion to the shopper's every whim. He is teaching them humility.
