Field experiments showed that removing crowded product displays creates more space, encouraging customers to slow down, stop more frequently and engage more with items. This can ultimately improve purchasing behaviour despite fewer products being directly visible.

The research also found that crowded aisles, particularly when shoppers use carts, can reduce comfort and limit browsing time. By identifying bottlenecks and simplifying store layouts, retailers can improve both customer experience and commercial performance, offering a low-cost strategy to boost sales while making shopping environments more accessible and less stressful for consumers.
