Interpersonal accuracy correlates modestly across different domains. Although some research has explored factors that predict accuracy within specific domains of interpersonal judgment (e.g., social attributes), whether any variables might predict interpersonal accuracy generally across different domains remains in question. Subjective socioeconomic status (SES) has recently emerged as an important moderator of various social cognitions, such as contextual focus and empathic accuracy. Moreover, people lower in SES tend to show greater interpersonal engagement and attention; thus, we wondered whether individuals with lower subjective SES might exhibit superior interpersonal accuracy in multiple domains. Indeed, across four studies, we found that subjective SES inversely correlated with accuracy in three different domains of interpersonal accuracy: social attributes, situational affect, and emotion. These findings therefore demonstrate that subjective SES may predict broad interpersonal accuracy abilities and suggest that, despite modest relationships between different types of first impression accuracy, the correlates of such accuracy can still operate across domains.
