Recent research challenges the idea that general intelligence relies on global brain efficiency or small-world architecture. A large-scale analysis shows that whole-brain measures do not predict cognitive ability, while node-level patterns—especially within-module degree in specific regions like the temporal poles and cerebellum—are linked to intelligence.

This article is of interest to psychology because it clarifies how cognitive abilities relate to brain structure, highlighting the importance of local connectivity over global network properties. It underscores the value of large, diverse datasets in testing theories of intelligence and the specificity of neural mechanisms.
