The interactive effect of numerical precision and message framing in increasing consumer awareness of food waste issues

Abstract

Food waste has become a pressing problem in the world, leading to a range of economic, social, and environmental issues. As a result, there are increasing calls to develop effective messages that can increase consumer awareness of food waste and its negative impacts. Drawing upon a recent research on the influences of numerical precision on consumer decision making, the present research tests the ‘match-up’ effects between numerical precision and message framing on consumer awareness of food waste issues. Two experimental studies (Ntotal = 799) show that more (vs. less) precise numerical information can increase consumer awareness of food waste issues when combined with a loss message framing, whereas less (vs. more) precise numerical information is more effective when combined with a gain message framing. This research also examines the role of time availability as a boundary condition, such that when perceptions of time availability is heightened or reduced, the predicted effects are attenuated. Theoretical and managerial implications are discussed.
