How does shame affect social cohesion? Prior work has drawn divergent conclusions to this question because shame can spur maladaptive behaviors for people who experience it. However, past work has overlooked the interindividual effects of shame-how one's expression of shame affects people who witness it. We investigated these social-learning effects of shame and identified norm transmission as a reliable route by which shame facilitates social cohesion. Across five studies and two supplemental studies with U.S.-based adult participants (N = 3,726), we manipulated whether someone conveys shame, no specific emotion, or other discrete emotions regarding their behavior. We then assessed the effect of this emotional expression on participants' norm inferences and norm-conforming behavior. We found that shame broadcasts particularly strong signals about social norms, and people adjust their behavior to align with these norms. We discuss how these findings challenge common conclusions about shame and generate insights about shame's influence on social life.
