A study conducted by the Weizmann Institute of Science has found that ants exhibit better group intelligence than humans when maneuvering a large load through a maze. While humans have an advantage over ants when working individually, ants are able to defeat groups of people when they join forces. The study, published in the Proceedings of the National Academy of Sciences, involved creating a real-life version of the 'piano movers puzzle' for ants and humans to solve. The researchers found that ants worked together in a calculated and strategic manner, exhibiting collective memory, while humans struggled to improve their performance when working in groups.
