Weight and social comparison: Does the weight of a stranger affect a person's perception of their own weight?

Research suggests that social context affects individuals’ perception of their own weight. Using face-to-face interviews as the social context, we analyze the effect of interviewers’ (N=90) body mass index on respondents’ (N=3068) selfperceived weight level. Respondents reported a higher weight level when the interviewer had a higher body mass index (absolute social comparison). Female respondents reported a lower weight level if interviewers had a higher body mass index than they did (relative social comparison). Results suggest that weight perception reflects both absolute and relative social comparison, especially among women. Future research should consider causation and self-selection when
studying social context and body image.
