Prejudice toward individuals with obesity: Evidence for a pro-effort bias.

Three studies examined the role of causal beliefs in weight stigma in order to better understand people's evaluations of individuals with obesity. Participants viewed weight-related information about a target individual and evaluated that target on various dimensions. Study 1 showed that offset effort information (i.e., information about effort to lose weight) had a greater impact on participants' evaluations of individuals with obesity than did other causal information, such as onset control and offset ability. Study 2 extended this finding by demonstrating that the duration of effort invested to lose weight is also important in determining participants' evaluations of individuals with obesity. Study 3 replicated the effect of effort (albeit in terms of effort to maintain a healthy lifestyle) on evaluations of individuals without obesity. Furthermore, in all 3 studies, disgust mediated the association between perceived effort and desire for social distance from the target. These findings highlight a key role for effort and disgust in weight stigma, and suggest that the negative evaluations of individuals with obesity might in part reflect a pro-effort bias. The present research has important implications for strategies to reduce weight stigma, and may even inform strategies to reduce social stigma beyond obesity, such as drug addiction.
