This is a fascinating study, it reveals that ant groups significantly improve their problem-solving abilities through effective cooperation, whereas human groups do not show similar enhancements and can even perform worse when communication is limited. This difference is attributed to ants’ simple cognitive structures, which facilitate seamless collaboration, while humans’ complex cognition leads to variations that hinder efficient group performance. It seems that the advantages of collective cognition depend on the underlying cognitive and cooperative mechanisms of the species… found it a great read.
