The “romantic view” of ants is that each single ant is stupid, but together “emerges some kind of collective intelligence.” But they’re not stupid at all. The ants rotate jobs, alternating between carrying the load and “scouting out” the scene. If any scout ants notice their loaded down comrades drift off course, they grab hold and stubbornly push the disoriented group back on track. The individuals come with the solution. The group gives it the muscle power.
