Peer presence promotes popular choices: A “Spicy” field study on social influence and brand choice

subject

description

Abstract Retail research has highlighted how the presence of others can affect consumers' brand evaluations, purchase intentions, and choice behavior. This field study investigated whether the presence (vs. absence) of peers and other consumers, respectively, could influence consumers' propensity to purchase popular brands (i.e., a market leader) within a given product category. Consumers at a supermarket were observed when standing in front of a spice shelf and their choices were analyzed as a function of whether they shopped alone or in the presence of peers versus other consumers. The results revealed that peer presence, but not the mere presence of other consumers, increased consumers' inclination to make popular brand choices, and that this effect was mediated by their stated familiarity with the chosen brand. As such, peer presence seems to increase consumers’ reliance on heuristics and the accessibility of concepts linked to popularity, leading to congruent popular brand choices. Moreover, consumers shopping in the presence of others generally took a longer time before choosing a brand and touched slightly more products in the presence of other consumers. Taken together, these results contribute to theory refinement in social influence from ecologically valid conditions and offer a set of implications for companies, store managers, and people working in the food industry.
