Extraverts are often characterized as highly social individuals who are highly invested in their interpersonal interactions. We propose that extraverts’ interaction partners hold a different view—that extraverts are highly social, but not highly invested. Across six studies (five preregistered; N = 2,456), we find that interaction partners consistently judge more extraverted individuals to be worse listeners than less extraverted individuals. Furthermore, interaction partners assume that extraversion is positively associated with a greater ability to modify one’s self-presentation. This behavioral malleability (i.e., the “acting” component of self-monitoring) may account for the unfavorable lay belief that extraverts are not listening.
