Abstract:

Collective intelligence depends on groups’ ability to integrate dispersed knowledge, yet research offers mixed evidence on whether knowledge diversity enhances collective outcomes. We propose that this inconsistency reflects a neglected structural condition: whether collaboration networks form an integrated system capable of mobilizing heterogeneous knowledge. We introduce structural integration as a system-level property conditioning the value of knowledge diversity. Using a four-year panel of 329 department-year observations, we find that structural integration strengthens collective intelligence and attenuates the negative effects of diversity in fragmented networks, highlighting connectivity as the infrastructure enabling collective capability.
