<p>Psychological entitlement is the belief that one deserves more. As an environmental factor that is systematically related to individuals’ beliefs about themselves and subsequent social behaviors, socioeconomic status is also closely related to psychological entitlement. However, previous research on this relationship remains insufficient. In the present three studies, we aimed to explore the relationship between socioeconomic status and psychological entitlement and its potential internal mechanisms. We recruited senior high school and college school students in Northwest China as participants. In the first study, we found that subjective socioeconomic status had a stronger explanatory power of psychological entitlement than objective socioeconomic status. In the following studies, we found that explicit self-focused attention (Study 2a) and implicit self-focused attention (Study 2b) mediated the positive relationship between socioeconomic status and psychological entitlement, respectively. Moreover, the results show that self-compassion only moderated the relationship between explicit self-focused attention (not implicit self-focused attention) and psychological entitlement. For lower self-compassion individuals, explicit self-focused attention was positively related to psychological entitlement. While for higher self-compassion individuals, there was no significant correlation between explicit self-focused attention and psychological entitlement. These findings expand the social cognitive theory of social class and have implications for understanding beliefs behind different socioeconomic statuses and taking corresponding measures.</p>
