Marketing professor to publish article in top journal in marketing discipline

Marketing professor Andrea Tangari had an article accepted in the Journal of Marketing titled “That’s Not So Bad, I’ll Eat More! Backfire Effects of Calories-per-Serving Information on Snack Consumption.” The Journal of Marketing is an A+ on all school’s marketing lists and the top journal in the marketing discipline. 


This research investigates how provision of calories-per-serving information on serving size labels affects snack consumption quantity. Drawing from expectancy-disconfirmation theory, this research shows that providing calories-per-serving information can ironically create a consumption backfire effect (consumers eat more when presented with calories-per-serving information) for perceptually unhealthy snacks, but not perceptually healthy snacks. The authors find that this effect arises when calorie expectations are higher than the posted calories-per-serving level—a frequent occurrence due to stated serving sizes that are typically smaller than amounts consumed in one sitting. The authors also show that attention to calorie information plays a key role such that the backfire effect occurs among consumers who pay more attention to calorie information. Further, motivational factors including individual differences and perceptions of the risk associated with consuming a snack also play a role in driving consumption differences. The authors offer managerial, policy, and consumer welfare implications, including proposing and testing larger stated serving sizes as an intervention.
