Social norm perception is ubiquitous in small groups and teams, but how individuals approach this process is not well understood. When individuals wish to perceive descriptive social norms in a group or team, whose advice and behavior do they prefer to rely on? Four lab studies and one field survey demonstrate that when individuals seek information about a team’s social norms they prefer to receive advice from lower-ranking individuals (Studies 1–4) and give greater weight to the observed behavior of lower-ranking individuals (Study 5). Results from correlation (Study 3) and moderation (Study 4) approaches suggest this preference stems from the assumption that lower-ranking team members are more attentive to and aware of the descriptive social norms of their team. Alternative mechanisms (e.g., perceived similarity to lower-ranking team members, greater honesty of lower-ranking team members) were also examined, but no support for these was found.
