Diversity is highly valued in modern societies due to its positive impact on social cohesion, tolerance, and economic vibrancy. However, diversity is a complex issue with various attributes, and not all forms of diversity are beneficial. Academic collaboration, measured through co-authorships, provides an effective domain to study diversity and its impact on success. We explore homophily in scientific collaborations based on age, gender, affiliation, and ethnicity. We find signs of homophily in ethnicity, gender, and affiliation, with ethnicity showing a steady increase over time. Ethnic diversity is strongly associated with research impact. Additionally, diversity benefits groups more than individuals. We also examine the evolution of diversity over time, team size, and number of collaborators. This comprehensive analysis provides a richer understanding of diversity’s effects.
