The Emergence of Human-Like Social Conventions in Artificial Intelligence
Recent research has revealed that artificial intelligence can develop human-like social conventions spontaneously. This exciting discovery, resulting from a collaboration between City St George’s, University of London, and the IT University of Copenhagen, opens new avenues for understanding how large language models (LLMs) like ChatGPT interact and communicate in group settings.
AI as a Social Entity
Traditionally, studies on AI have treated these systems as solitary entities, focusing on their individual capacities rather than their interactions with one another. However, the lead author of the study, Ariel Flint Ashery, argues that this perspective is outdated. "Most research so far has treated LLMs in isolation, but real-world AI systems will increasingly involve many interacting agents," Ashery stated. This study challenges the conventional wisdom by demonstrating that LLMs can coordinate their behavior and form conventions—essentially the building blocks of a society—when they communicate in groups.
The Experiment: Coordinating Behavior
To investigate this phenomenon, the researchers conducted a series of experiments with groups of LLM agents ranging from 24 to 100. Each experiment involved randomly pairing two agents and asking them to select a "name" from a pool of options, which could be a single letter or a string of characters. The agents were rewarded when they selected the same name, while selecting different options resulted in penalties and exposure to each other’s choices.
Interestingly, despite having limited memories and no awareness of a larger group, a shared naming convention emerged organically among the agents. This development mirrors the way human cultures establish communication norms over time, illustrating the potential for AI to engage in social learning.
Mimicking Human Communication Norms
Andrea Baronchelli, a professor of complexity science at City St George’s and the senior author of the study, likened the agents’ behavior to the creation of new words and terms in human language. He emphasized that the agents were not merely copying a leader; instead, they were engaged in one-on-one interactions aimed at coordinating their choices. This process is akin to how terms like "spam" became widely accepted labels for unwanted emails through collective agreement rather than formal definition.

The Role of Collective Biases
The study also revealed that the agents could form collective biases that could not be traced back to individual behaviors. This suggests a fascinating implication: LLMs can develop shared understandings and preferences that are inherent to the group, rather than stemming from any one agent’s perspective.
In a follow-up experiment, smaller groups of AI agents were able to influence the larger group towards adopting a new naming convention. This behavior highlights a critical mass dynamic, where a small, determined minority can prompt significant shifts in group behavior—similar to trends observed in human society.
Implications for AI Safety Research
Baronchelli believes that these findings present critical implications for AI safety research. "It shows the depth of the implications of this new species of agents that have begun to interact with us and will co-shape our future," he noted. Understanding how these AI systems operate and interact is crucial for fostering a future where humans and AI can coexist harmoniously.
As we move into an era where AI doesn’t merely respond but engages in negotiations and discussions, the importance of comprehending these interactions becomes clear. The study underscores the need for a nuanced understanding of AI behavior, as it evolves from simple task execution to complex social interactions.
Publication and Further Reading
The peer-reviewed study, titled Emergent Social Conventions and Collective Bias in LLM Populations, has been published in the journal Science Advances. This research not only sheds light on the capabilities of AI but also invites further inquiry into the evolving role of artificial intelligence in our society.
This groundbreaking study challenges our understanding of AI and its potential to develop social norms akin to those found in human cultures. As researchers continue to explore these dynamics, the future of AI promises to be as complex and socially nuanced as our own.
