Ants vs. Humans: A Battle of Collective Intelligence
In the animal kingdom, only two species have mastered the art of moving objects so large that cooperation is essential: humans and ants. But not all ants are created equal.Only 1% of the Formicidae family can work together to solve complex tasks, such as maneuvering a T-shaped object through narrow doorways. This experiment, a staple in computer science and artificial intelligence,was recently adapted by entomologists to compare the cognitive abilities of ants and humans. The results? Under equal conditions, ants outperform humans in collective intelligence.
The Longhorn Crazy Ant: A Master of Teamwork
The longhorn crazy ant (Paratrechina longicornis) is one of the rare species capable of such feats. Known for thier erratic, seemingly chaotic movements, these ants rarely travel in straight lines. yet, from this apparent disorder emerges a remarkable collective intelligence.
Researchers at the Weizmann institute of Science in israel, led by Ofer Feinerman, designed a challenging experiment to test the ants’ problem-solving skills. The task? Move a T-shaped wooden object through a series of increasingly narrow doorways, mimicking the path to their nest. To compare their performance with humans, the team created a human-sized version of the same setup.
The Experiment: Ants vs. Humans
The study, published in the Proceedings of the National Academy of Sciences, revealed fascinating insights into collective intelligence. While individual humans outperformed single ants, the dynamics changed dramatically in group settings.
| Comparison | Individual Performance | Small groups (6-9) | Large Groups (25 humans, 80 ants) |
|————————–|—————————-|————————-|—————————————|
| Humans | Superior | Struggled with decision-making | Less efficient in large groups |
| Ants | Inferior | Improved coordination | Higher success rates due to emergent memory |
Emergent Intelligence: The Ants’ Secret Weapon
“An ant that carries a load on its own doesn’t remember the way it moved for very long: it changes constantly, especially if it hits a wall,” explains Feinerman. “The group of ants can remember the direction in which they were headed for a few seconds ago and persist in walking in that direction, even if an edge of the load they are carrying hits a wall.”
This phenomenon, termed emergent intelligence,is a memory that the group possesses but not the individual. For the longhorn crazy ant, this ability may have evolved as a survival mechanism. “This is a species of ants that tend to give up at the slightest conflict,” Feinerman notes. “If a neighboring colony arrives looking for food,they will chase the crazy ants away. Their only chance is to cooperate and transport food quickly.”
Humans: The Struggle with Group Dynamics
While humans excel individually, our performance in groups ofen falters.The study highlights how larger human groups struggle with decision-making, a stark contrast to the ants’ seamless coordination. This raises intriguing questions about the nature of collective intelligence and how it manifests differently across species.
Conclusion: Lessons from the Ant Colony
The longhorn crazy ant’s ability to solve complex problems through teamwork offers a fascinating glimpse into the power of collective intelligence.As Feinerman puts it,“They become amazing problem-solvers when it comes to transporting large loads in complex environments.”
For humans, the study serves as a reminder of the challenges we face in group settings. Perhaps, by studying the ants, we can unlock new ways to enhance our own collective decision-making.

When Ants Outperform Humans: A Fascinating Look at Collective Intelligence
In a groundbreaking experiment, researchers discovered that under certain conditions, ants can outperform humans in problem-solving tasks.While humans typically excel in complex challenges, a unique variation of the experiment revealed that ants, specifically crazy ants, were more efficient when communication was restricted. This finding sheds light on the cognitive abilities of both species and how they adapt to limitations.
The experiment: Humans vs. Ants
The study involved a task where participants—both humans and ants—had to move a T-shaped object through a maze.Humans, equipped with advanced cognitive abilities, were generally more efficient. However, when researchers restricted communication among human participants, the tables turned.
to ensure fairness, human subjects wore masks and dark sunglasses, effectively limiting their ability to speak or gesture. The edges of the T-shaped object were fitted with force sensors to measure the intensity and direction of movements, the only means of communication available. Surprisingly, in this setup, ants outperformed humans in most attempts.
“People in a non-communicative group (i.e., with a communication scheme similar to that of ants) start to behave a bit more like them and, in so doing, their performance levels decrease,” explains Cognitive Differences: Humans and Ants
The experiment highlighted stark differences in how humans and ants approach problem-solving. Humans rely on mental mapping and long-term memory. “An individual person transforms the maze in his mind into a graph, which is an extreme dimensional reduction. Instead of exploring the whole complex maze,only a handful of nodes are explored,” says Feinerman. In contrast, ants lack the ability to mentally reproduce the puzzle. A single ant lifts the load and tries moving it in all directions, a method that often surpasses other species.Most animals, when faced with a similar task, would pull the object along the shortest path, even if it doesn’t fit. Ants, however, adapt and explore multiple approaches. Interestingly, when ants work in groups, they exhibit human-like characteristics. “They acquire some human-like characteristics,” Feinerman notes, emphasizing the power of collective intelligence. The study yielded two primary insights: The authors conclude, “Our results exemplify how simple minds can easily take advantage of scalability, while more complex minds need ample communication to cooperate efficiently.” | Aspect | Humans | ants | This experiment not only deepens our understanding of ant behavior but also offers insights into human cognition. It underscores the importance of communication in human collaboration and highlights how simpler systems can achieve remarkable efficiency.

The study reminds us that even the smallest creatures can teach us valuable lessons about teamwork, adaptability, and the power of collective intelligence. The study raises significant questions about how humans can improve collective decision-making and problem-solving. While humans excel in individual tasks, our reliance on communication can sometimes hinder group performance, especially in high-pressure or constrained environments. Here are a few takeaways: The study suggests that there is much to learn from the natural world, notably from species like ants that have evolved highly efficient systems of collective intelligence. By studying their behavior,we might uncover new strategies for improving human teamwork,especially in fields that require rapid problem-solving and adaptability,such as emergency response,engineering,and even artificial intelligence. The comparison between ants and humans offers a captivating glimpse into the nature of intelligence and cooperation. While humans have the advantage of advanced cognitive abilities, ants demonstrate that simplicity and collective effort can be equally powerful. As Feinerman aptly puts it, “they become amazing problem-solvers when it comes to transporting large loads in complex environments.” Perhaps the key to unlocking our full potential lies not in outsmarting nature, but in learning from it. By embracing the lessons of the ant colony, we might find new ways to enhance our own collective intelligence and tackle the challenges of an increasingly complex world. What do you think?
