From cosmetic surgeries to jaw wiring, individuals seem willing to do almost anything to lose weight (Garrow & Gardiner., 1981; Spadine & Patterson., 2022). Purveyors of weight loss products and strategies typically propose the idea that if people consume fewer calories and exercise more, they should be able to lose weight, a concept called weight controllability (Reinka et al., 2021). Weight controllability, along with weight stigma, which is the societal denigration of people in larger bodies, has led people to undergo dangerous measures. These measures, such as extremely restrictive diets, are taken by higher weight individuals to reduce weight and no longer be in a larger body (Lawson et al., 2021). The current study examined how weight controllability beliefs drive externalized weight stigma. Our sample consisted of 455 participants (222 cisgender women, 223 cisgender men, 3 nonbinary individuals, 1 transgender individual, and 6 individuals who preferred not to respond). Participants’ ages ranged from 18 to 79 years (M = 44.82, SD = 13.78). Participants were recruited online through CloudResearch and were residents of the United States at time of study completion. We randomly assigned participants to one of four vignettes. Each vignette described a woman who was either normal weight or obese according to the Body Mass Index (BMI) scale. Furthermore, each vignette described the woman as having an autoimmune disease that either decreased her ability to control her weight or had unspecified consequences. After this, we asked participants to evaluate the woman in the vignette with a modified Attitudes Toward Obese Patients scale (Puhl et al., 2014). Additional exploratory analyses were conducted with the Blame Attributions Scale (Ebneter & Latner, 2013) and Weight Controllability Beliefs Scale (Laliberte et al., 2007). We found that participants assigned the vignette of a higher weight woman scored lower on the Attitudes Toward Obese Patients Scale, meaning they held more negative perceptions of the woman. However, we did not find a significant interaction between weight and weight controllability. This suggests that weight stigma is prevalent regardless of the perceived weight controllability of an individual. Nonetheless, future research is needed to further test this relationship, as various limitations such as socially desirable responding, may have played a role in the current study.
