Collective intelligence describes the capacity of groups to achieve levels of performance that cannot be explained by the abilities of their individuals. The existence of collective intelligence implies that groups composed of mixed-ability members may outperform groups of high ability. Here, we examine when such benefits emerge in humans and whether it is driven by collaboration. We designed a collaborative multiplayer online game and manipulated team composition (mixed-ability vs. high-abilit
