Since the late 1980s, Business School marketing professor Itamar Simonson has looked for ways to understand how consumers make choices. Much of his work debunks the accepted theory that giving consumers what they want and making a profit are the most basic principles of marketing. Customers may not know what they want, and second-guessing them can be expensive, says the professor who teaches MBA and PhD marketing and consumer decision-making courses. In Simonson's words, “The benefits and costs of fitting individual customer preference are more complex and less deterministic than has been assumed”.
That's because “customer preferences are often ill-defined and susceptible to various influences, and in many cases, customers have poor insight into their preferences”. In one of his recent papers, Simonson tackles the issue of one-to-one marketing and mass customization. Supporters of these marketing approaches have suggested that learning what customers want and giving them exactly what they want will create customer loyalty and an insurmountable barrier to competition.
In an example taken to the extreme in the 2002 movie Minority Report, Tom Cruise's character runs through a shopping mall past talking billboards that recognize him by name and urge him to buy products he had earlier expressed an interest in such as jeans and Ray-Bans, the ultimate in personalized advertising. But Simonson has this to say: The fact that consumer preferences are often fuzzy, unstable, and manipulatable is unlikely to change. So, the effectiveness of methods to give customers exactly what they want has been grossly exaggerated.
In studies, he has learned that even when customers have well-defined preferences and receive offers that fit those preferences; it is far from certain that the response to such offers will consistently be more favourable than those directed at larger market segments.
It's all psychology. Consumers with well-defined
