Researchers from the University of Bonn have taken a comprehensive look at how scientists study consumer behavior in supermarkets. Their review, published in the International Journal of Consumer Studies, covers everything from real-life grocery stores to lab-based shelves, online supermarkets, and virtual reality environments. The goal: to map which type of supermarket settings researchers use and how they use them to better understand how the context of shopping itself can influence consumer behavior. This, in turn, helps policymakers and businesses to interpret research findings, adapt current strategies, or design new interventions.
