Social Influence

Social influence involves the changing of a person's attitude or behavior through the doings of another person. Here we focus on the realm of consumer behavior and on the factors that cause one individual to comply with another's request. The starting point in ascertaining what are the most successful influence strategies was an investigation of the techniques that are most successful in professions dependent on their ability to induce compliance (e.g., salespeople, fund-raisers, advertisers, political lobbyists, cult recruiters, negotiators, and con artists). What emerged from this period of systematic observation was a list of six principles on which compliance professionals base most of their successful influence attempts: (i) reciprocity - repaying a gift, favor, or service; (ii) consistency - acting consistently with prior commitments; (iii) social validation - following the lead of similar others; (iv) liking - accommodating the requests of those we know and like, (v) authority - conforming to the directives of legitimate authorities, and (vi) scarcity - seizing opportunities that are scarce or dwindling in availability. We provide a summary of the principles and the scientific evidence regarding how each principle functions to influence consumer behavior.
