Gruen Effect

The Gruen Effect occurs when a shopping environment is intentionally designed to influence and enhance a customer's mood and perception, encouraging longer stays and increased spending. Named after architect Victor Gruen, it involves layout, lighting, music, and scenery that create a comfortable, engaging atmosphere—often mirroring real-world experiences—making shoppers feel relaxed, unaware of the commercial intent. This psychological response can lead to impulsive purchases, as the environment subtly fosters a sense of ease and connection, transforming the shopping trip into a more enjoyable and immersive experience.
