Leaning into risk: How slanted typeface logos increase perceived risk of efficacious products

Marketing practice commonly uses slanted typeface logos on product packaging to convey movement and vitality, yet existing research has paid limited attention to the potential conflict between this low-level visual feature and the core claims of specific products. Drawing on the elaboration likelihood model (ELM), this research examines when and why slanted typeface logos on packaging increase consumers' perceived risk of efficacious products, revealing the underlying mechanism and boundary condition. Across three controlled experiments and one incentive-compatible experiment, this research manipulates the form of typeface logos on packaging and evaluates its effects and subsequent behavioral responses. Study 1 shows that, compared with an upright typeface logo, a slanted typeface logo increases consumers' perceived risk of efficacious products. Study 2 supports the mediating role of design instability: a slanted typeface logo triggers a visually perceived sense of imbalance, which further induces consumers’ risk inferences about the product; meanwhile, arousal, perceived movement, and perceptual fluency do not emerge as significant mediating mechanisms. Study 3 identifies the moderating role of cognitive load, showing that high cognitive load amplifies the effect of a slanted typeface logo on perceived risk. Study 4 further provides behavioral evidence through an incentive-compatible experiment, showing that consumers are less likely to choose the product in the slanted typeface logo condition. Overall, this research reveals a boundary of the visual marketing principle that “slanting implies vitality” in the context of efficacious products. These findings enrich theoretical understanding of the boundary conditions under which peripheral visual cues operate within the ELM framework and offer practical implications for the context-specific management of brand visual identity systems.
