Past studies find that lower socioeconomic status (SES) individuals are less likely to donate organs. Building on the extended self literature, we propose that this effect occurs in part because the body is more central to the sense of self of lower-SES individuals. We test our predictions across seven studies (N = 8,782) conducted in different countries (United States and Brazil) with qualitative, observational, and experimental data in controlled and field settings. Results show that lower-SES individuals ascribe a greater weight to their bodies in forming their self-concept, which reduces their willingness to donate organs.
