The depth of explanation about novel products influences consumer preferences and willingness to pay, according to a study led by the University of Colorado Boulder and Brown University.

When it comes to descriptions about the functions of new and unusual goods -- such as a self-watering plant system, special gloves for touchscreens or an eraser for wall scratches -- some people prefer minimal details. Dubbed 鈥渆xplanation foes鈥 in the study, they gain a strong sense of understanding and desire for products through shallow explanations.

In contrast, other people -- dubbed 鈥渆xplanation fiends鈥 in the study -- derive desire for products from deep and detailed explanations.

鈥淭here are these two different types of consumers,鈥 said lead author Phil Fernbach, assistant professor of marketing at CU-Boulder鈥檚 Leeds School of Business. 鈥淥n these two sides, consumers differ in the amount of detail that makes them feel like they understand and -- because of that feeling of understanding -- the amount of detail that will make them prefer a product.鈥

A paper on the subject was published online today in the Journal of Consumer Research.

Researchers say the study results can help consumers make better decisions.

鈥淲e鈥檙e not making a value judgment on whether it鈥檚 better to be an 鈥榚xplanation foe鈥 or 鈥榝iend,鈥 鈥 said Fernbach. 鈥淵ou don鈥檛 have to want to know how stuff works, but make sure that your intuition about whether you understand a product is based on objective information and not just a feeling.鈥

In one part of the study, participants were given varying explanations of a new tinted food wrapper product. 鈥淓xplanation foes鈥 highly rated their understanding and preference for the item when they read a simple description of how its 鈥渨hite coloring protects food from light that causes it to spoil, thereby keeping food fresh for longer.鈥

鈥淓xplanation fiends鈥 highly rated their understanding and preference for the food wrapper when they read a more detailed description of how 鈥渁toms in the tinting agent oscillate when hit by light waves causing them to absorb the energy and reflect it back rather than reaching food, where it would break the bonds holding amino acids together, thereby keeping food fresh for longer.鈥

The study also found that 鈥渆xplanation foes,鈥 who are more common, tend to have an inflated sense of understanding about novel products. Their heightened perception disappears and their willingness to pay decreases when they attempt to explain how a product works.

Conversely, 鈥渆xplanation fiends鈥 tend to have a more conservative sense of understanding about novel products. For them, attempting to explain how a product works does not have a negative effect on their sense of understanding and their opinion of the product stays the same or increases, according to the study.

Attitudes toward explanation were predicted by a cognitive reflection test that measures how much people naturally engage in deliberative thinking. Each test question elicits an intuitive but incorrect answer and participants who impulsively respond tend to err. These participants are the 鈥渆xplanation foes鈥 who prefer less explanation.

In contrast, those who inhibit their initial responses to the cognitive reflection test and think more deeply tend to correctly answer. These participants are the 鈥渆xplanation fiends鈥 who prefer more in-depth descriptions.

While the study can help consumers with better decision-making, it also yields advice for marketers.

鈥淢arketers should target these different consumer groups with different types of explanations,鈥 said Steven Sloman, a study co-author and professor of cognitive, linguistic and psychological sciences at Brown University.

Robert St. Louis and Julia Shube also were co-authors of the study. They were undergraduate students at Brown during the research. Unilever, a consumer goods company, supported the study. 听
