Here’s the trick that supermarkets use to control how quickly (or slowly) you walk

New research has shown that supermarkets can control our walking speed while we shop, just by changing the pattern on the floor.

An interesting (and slightly unnerving) new study carried out by the Rotterdam School of Management, Erasmus University, has demonstrated that retail managers can persuade their customers to walk at the ideal pace (either more quickly or slowly), simply by changing lines and patterns on the shop floor. The study's lead researcher, Bram Van den Bergh, says that retailers put more thought into this than you might think. "Managing the flow of customers can be a challenge for retailers," he revealed. "When customers rush through the store, they miss interesting products and buy less. Spending too much time in front of the shelves can lead to annoying congestion in the aisles, which also leads to declining sales." He continues, "It has been known for some time that walking speed plays an important role in shoppers' purchasing decisions. "But until now it was unclear what retail managers could do to influence the pace of their customers. This research was set up to find out how they might achieve this." The researchers observed 4,000 people in a series of experiments that were conducted both in a store and in a lab. If lines on the shop floor were 20 inches apart, they found it created the optical illusion that the end of the aisle was further away - meaning that shoppers tended to slow their pace. However, if the lines were further apart, shoppers tended to speed up, thinking that the end is nearer. It looks like retailers might want to go with the first 20 inch option as slower shoppers were found to be much better at recalling what products they had seen, compared to those who sped through. Bram Van den Bergh says that the findings relate to something called 'goal gradient theory'. This theory basically states that when an individual is closer to their goal (in this case, the end of a supermarket aisle) they will walk faster to reach it. I'd like to see them try this experiment again, but with a toddler in tow.
