Body-Positive Messaging Backfires for Indulgent Food Brands

Tianyujun Lu, Yann Cornil, and Darren W. Dahl · Dissertation Essay 1

Under 1st round review at Journal of Consumer Research

Body-positive messaging is increasingly adopted by brands, often aiming to signal inclusivity, warmth, and social awareness. This research identifies an important boundary condition: such messaging can backfire when adopted by indulgent food brands. Across four experiments, an online simulation, and an archival field study, consumers respond less favorably when indulgent food brands, compared with healthy food or non-food brands, engage in weight-related body-positive messaging. This backlash emerges in brand attitudes, incentive-compatible product choice, and social media responses. The effect is specific to weight-related forms of body positivity and does not generalize to non-weight-related forms, such as skin- or disability-related body-positive messaging. The backlash is driven by two related inferences by consumers: the perceived insincerity of the brand, as well as its perceived Machiavellianism — a belief that the brand is strategically exploiting a social movement while deflecting responsibility for weight-related concerns associated with its products.

Organizational Behavior and Human Decision Processes

Explicitly signaling one’s identity with a historically disadvantaged group has become increasingly common practice by leaders who champion diversity, equity, and inclusion (DEI). Yet little is known about whether or how identity signaling shapes leadership selection decisions. Across a pilot study and six experiments, we examine how identity signaling in racialized and gendered contexts affects aspiring leaders’ chances of success. We find that candidates who explicitly signal an otherwise visible identity are less likely to be selected for leadership positions than demographically similar candidates who do not signal their identity. This effect emerges across leadership selection settings and operationalizations of identity signaling, while remaining robust across evaluators with differing political ideologies. Revealing the mechanism at play, we show that this penalty arises because identity signaling alters expectations about how candidates are likely to perform in leadership roles. Specifically, candidates who signal their identity are expected to be less fair and impartial in how they would exercise discretion and enact procedural justice.
