Socio-diversity, or the variety of human behaviors, has profound implications for social systems. While it fuels innovation, productivity, and collective intelligence, it also complicates communication and undermines trust. This talk discusses how some fundamental characteristics of social networks can support or hinder socio-diversity. Employing models of cultural evolution, mathematical analysis, and numerical simulations, I argue that pronounced inequalities in the distribution of connections tend to obstruct socio-diversity. In contrast, the prevalence of close-knit communities, a scarcity of long-range connections, and a significant tie density tend to promote it.
