Choice Architecture and Environmental Influence on Behavior

Key Insight

The environment of a store can manipulate customer thoughts and purchasing behavior. For example, grocery stores often place fruit and vegetable sections first, knowing that buying healthy items initially makes shoppers feel uplifted, leading them to purchase more 'junk food' later. The smell of baked goods stimulates shopping, so many stores bake bread on-site and pump its aroma throughout the day. Music also influences sales; studies in Britain found that French music significantly increased French wine sales, while German music boosted German wine sales.

Store layouts and product placement are strategically designed. Low-volume stores are typically near mall exits, as shoppers are still transitioning from the outside world. In department stores, women's shoe sections are often next to cosmetics, allowing bored customers to browse makeup while waiting for shoe clerks. Consumers often perceive products on the right side of a display as higher quality; an experiment with four identical pantyhose pairs showed the rightmost pair was rated highest by 40 percent of customers, followed by 31 percent, 17 percent, and 12 percent for the leftmost, with customers denying location influenced their choice.

Beyond direct placement, social and psychological factors affect behavior. People eat more when dining with others: 35 percent more with one companion than at home, 75 percent more with a party of four, and 96 percent more with seven or more. Consumers also exhibit dual tastes, preferring certain items for immediate use (e.g., 'Avatar' for tonight) versus others for later (e.g., 'The Piano'). For major purchases like homes, initial impressions are crucial; a California builder sold $10 million houses by ensuring an immediate view of the Pacific Ocean and a pool upon entry, making later considerations less important.
