集体智能的计算基础：资源多=解决问题更高效且策略不同
The Computational Foundations of Collective Intelligence
- 用计算资源视角解释集体为何胜过个体
- 动物导航案例显示集体用全新策略解难题
- 适合研究群体决策与分布式系统的人看
为何集体在解决某些问题时优于个体？根本原因在于集体拥有更多计算资源：更丰富的感官信息、更大的记忆容量、更强的处理能力以及更多行动方式。尽管分布式结构带来协调挑战，但集体资源优势直接催生了群体智慧、集体感知、分工协作和文化学习等现象。本框架还提出可验证的预测，关于分布式推理与情境依赖行为切换的能力。通过动物导航与决策的案例研究，证明集体不仅能更有效地解决问题，还能采用与个体截然不同的策略。
原文摘要 · Abstract (English)
Why do collectives outperform individuals when solving some problems? Fundamentally, collectives have greater computational resources with more sensory information, more memory, more processing capacity, and more ways to act. While greater resources present opportunities, there are also challenges in coordination and cooperation inherent in collectives with distributed, modular structures. Despite these challenges, we show how collective resource advantages lead directly to well-known forms of collective intelligence including the wisdom of the crowd, collective sensing, division of labour, and cultural learning. Our framework also generates testable predictions about collective capabilities in distributed reasoning and context-dependent behavioural switching. Through case studies of animal navigation and decision-making, we demonstrate how collectives leverage their computational resources to solve problems not only more effectively than individuals, but by using qualitatively different problem-solving strategies.
