Ethnic diversity and value sharing: A longitudinal social network perspective on interactive group processes.

Area of Science:

• Social Psychology
• Organizational Behavior
• Sociology

Background:

• Group collaboration is increasingly diverse.
• While diversity's effects are studied, the underlying processes are under-researched.
• Shared values are crucial for group functioning but may be hindered in diverse groups.

Purpose of the Study:

• To investigate interpersonal processes behind value sharing in diverse groups.
• To examine 'social bonding' (tie formation, homophily) and 'social norming' (value convergence, influence).
• To compare these processes in low and high ethnic diversity groups over time.

Main Methods:

• Longitudinal social network analysis.
• Study of small interactive groups with varying levels of ethnic diversity.
• Tracking network tie formation, homophily, network convergence, and influence over time.

Main Results:

• Both low and high diversity groups exhibited social bonding, not along ethnic lines.
• Low diversity groups demonstrated social norming: relational values aligned with liked peers, and achievement values converged.
• High diversity groups showed no evidence of social norming.

Conclusions:

• Ethnic diversity significantly impacts social norming processes within groups.
• Social bonding occurs irrespective of diversity levels.
• Interventions targeting social norming are recommended to enhance value sharing in high diversity groups.
