Paco Underhill
Most retailers and consumer brands still design stores, formats, and digital journeys around what they think customers do, not what customers actually do. The gap between intent and behaviour at the shelf, the entrance, the checkout, and the screen is where margin leaks and category share moves. Closing that gap requires direct observation of human behaviour in commercial space, not surveys, not focus groups, not dashboards.
Paco Underhill is the environmental psychologist who founded the field of shopping anthropology, helping retailers, consumer brands, and developers understand what customers actually do inside commercial environments.

Biography
In 1986, almost no one was studying what customers actually did inside a store. Marketers had surveys, retailers had sales data, and architects had floor plans, but no one had a continuous record of human behaviour at the shelf. Envirosell, founded in New York that year, was built to fix that. Paco Underhill borrowed the basic premise of environmental psychology, that surroundings shape behaviour, and turned it into a fieldwork practice using video cameras, trained observers, and large-sample tracking inside live commercial space.
The output, after four decades, is a body of work that consumer brands and retailers across more than 50 countries have used to redesign stores, formats, packaging, and service flow. Envirosell’s client list spans more than a third of the Fortune 100. The categories range from grocery and food service to beauty, fashion, financial branches, telecoms, and malls. Underhill’s books, published by Simon & Schuster, took that work into the public domain. Why We Buy: The Science of Shopping has appeared in 27 languages and is taught in MBA and design schools globally. Call of the Mall, What Women Want, and 2022’s How We Eat extended the method into specific commercial terrains.
The work earned wider recognition through Malcolm Gladwell’s 1996 New Yorker profile, “The Science of Shopping,” one of the most reprinted articles in the magazine’s history. It introduced ideas that have since become standard vocabulary in retail design: the decompression zone at a store entrance, the butt-brush effect, the way physical adjacency shapes purchase decisions. Underhill’s role in this is specific. He is the figure most consistently named when the field is described.
He stepped back as CEO of Envirosell in 2020 and now advises through Peckshee LLC. The intellectual position has not changed. Stores, malls, food retail, and the consumer-facing parts of banking and telecoms remain the terrain, and direct observation of behaviour remains the method.
