You walk in for milk and leave with $50 worth of snacks. This isn't a lack of willpower; it's design. Retail psychologist Emily Thorne exposes the architectural and psychological manipulation of the grocery store in "The Aisles of Influence." Thorne breaks down the "Gruen Effect"—the state of confused, timeless disorientation that makes people buy more. She explains why essentials like milk are always at the back (forcing you to walk past everything else), why fruits are polished and lit to look fresher than they are, and the science of "shelf placement" (eye-level is buy-level). The book delves into sensory marketing: the smell of baking bread pumped into the air, the tempo of background music that dictates walking speed, and the confusing math of "bulk buys." Thorne empowers shoppers to recognize these triggers and stick to their list. It is a field guide to defending your wallet in the most carefully engineered environment on earth.
