This paper investigates the emergence of collective humility within teams, shifting the focus from individual or leader-centric perspectives. We employ a dynamic, relational approach to study how humility develops and spreads, especially through dyadic interactions. Drawing on social information processing theory, we examine how team members' expressions of humility influence their teammates. Further we examine the co-evolution of humility and advice networks, where humility impacts future advice-seeking behaviors and vice versa. Employing a longitudinal study of 64 teams, we find that perceived humility from a team member increases the subsequent reactionary humility of their teammate. Furthermore, the presence of advice ties amplifies the influence of expressed humility, resulting in greater reciprocal humility. The study also reveals that humility networks positively relate to team learning, which serves as a mediator between humility networks and team performance. Altogether we emphasize that even a small amount of humility can significantly impact team functioning and suggests the importance of prioritizing humility in teams. Our findings advance humility research by demonstrating its dynamic emergence within teams and highlight the importance of interpersonal relationships in shaping collective outcomes.
