The article's authors, Amna Kirmani of Southern Methodist University, and Margaret Campbell, of the University of Colorado at Boulder, explain that consumers, called "targets," are forever sparring with sellers, called marketing "agents," but the nature of this relationship is ever-changing depending on many variables. "We proposed and showed that consumer targets are active participants in interpersonal marketing persuasion. Because marketing agents are perceived as professional helpers and/or persuaders, the target's role is more complex than depicted in prior research."
It seems that consumers are pretty good at employing various strategies in the marketplace. If you have ever been in a store and evaded the salesperson by looking away or hiding behind a rack of clothing, you may be an expert sentry. Whereas if you show up to the car lot with a folder full of information or a price quote from another dealer, then you're a seeker.
"Goal seekers try to make use of the agent to achieve their own goals," the authors explain. "Persuasion sentries, on the other hand, guard against unwanted influence from the agent."
