Costly curves: How human-like shapes can increase spending

Can exposure to body shapes affect spending preferences? Because Western society associates thinness with economic value, we argue that a shape resembling thin human body types activates concepts related to positive financial outcomes, such as responsibility and hard work. The results of five experiments show that exposure to thin, human-like shapes influences consumer self-efficacy judgments and spending outcomes, depending on the perceiver's weight. In line with social comparison, we demonstrate that seeing a thin (vs. wide) human-like shape leads consumers with a high body mass index to make more indulgent decisions. Financial self-efficacy is highlighted as the underlying mechanism, and high resemblance to the human form is identified as a critical moderator. The findings of this research acknowledge visual similarity's role in stereotype knowledge activation and weight stereotypes' broad scope of influence.
