    "abstract": "Humans make decisions collectively by combining individual and social learning. Individuals benefit from groups when individual exploration fails to accurately assess the environment, a phenomenon known as the \"wisdom of crowds.\" Previous studies indicate that self-organizing group dynamics can reduce suboptimal biases in noisy environments, particularly in fully connected groups. However, agents often have only partial information due to cognitive and physical constraints. To explore how diverse social network structures influence the collective dynamics of social learners, we integrate a decentralized network with a social reinforcement learning model in repeated two-armed bandit tasks. Our results suggest that: 1. Social learning in a sparse network outperforms asocial solo learning in highly uncertain tasks. 2. The phenomenon \"less is more, and more is different\" holds true only when agents strategically balance individual and social learning. 3. The group size effect on collective performance is significantly influenced by network structures.",
