Recent work on social influence has highlighted the importance of socially supplied political expertise, crediting it with strengthening attitudes, resolving ambivalence, and encouraging political participation. However, in focusing on the consequences of socially supplied political expertise, scholars have made the implicit assumption that citizens have equal access to this resource and have largely ignored its distribution. Given that individuals are constrained by their social contexts, we are particularly troubled by this oversight, and thus use two nationally representative data sources to explore the distribution of expertise among and throughout the social networks of citizens. We find consistent evidence that existing resource inequalities reinforce the unequal distribution of expertise in social networks—a gender-moderated pattern that involvement in civil society may help remedy.
