Solipsistic Superintelligence is Unlikely to be Cooperative

Rakshit S Trivedi, Natasha Jaques, Logan Cross +2

AI's central challenge is shifting from capability to coexistence. The dominant paradigm in AI research focuses on developing powerful agents that treat the world as an exogenous a…

Evaluating Cooperation in LLM Social Groups through Elected Leadership

Ryan Faulkner, Anushka Deshpande, David Guzman Piedrahita +2

Governing common-pool resources requires agents to develop enduring strategies through cooperation and self-governance to avoid collective failure. While foundation models have sho…

Stabilising Generative Models of Attitude Change

Jayd Matyas, William A. Cunningham, Alexander Sasha Vezhnevets +3

Attitude change - the process by which individuals revise their evaluative stances - has been explained by a set of influential but competing verbal theories. These accounts often…

A Theory of Appropriateness That Accounts for Norms of Rationality

Joel Z. Leibo, Alexander Sasha Vezhnevets, Manfred Diaz +10

We propose a society-first theory of normative appropriateness where individuals, modeled as pre-trained actors with cognitive architectures analogous to Large Language Models (LLM…

A Generative Model of Conspicuous Consumption and Status Signaling

Logan Cross, Jordi Grau-Moya, William A. Cunningham +2

Status signaling drives human behavior and the allocation of scarce resources such as mating opportunities, yet the generative mechanisms governing how specific goods, signals, or…

Social physics in the age of artificial intelligence

The Anh Han, Joel Z. Leibo, Tom Lenaerts +4

Artificial intelligence (AI) systems are rapidly becoming more capable, autonomous, and deeply embedded in social life. As humans increasingly interact, cooperate, and compete with…

How LLMs Distort Our Written Language

Marwa Abdulhai, Isadora White, Yanming Wan +4

Large language models (LLMs) are used by over a billion people globally, most often to assist with writing. In this work, we demonstrate that LLMs not only alter the voice and tone…

Evaluating Collective Behaviour of Hundreds of LLM Agents

Richard Willis, Jianing Zhao, Yali Du +1

LLM-powered AI assistants acting on behalf of users can produce poor collective outcomes at scale. We introduce a framework for evaluating their emergent behaviour in social dilemm…

Persona Generators: Generating Diverse Synthetic Personas for Arbitrary Contexts

Davide Paglieri, Logan Cross, William A. Cunningham +2

Evaluating AI systems that interact with humans requires understanding their behavior across diverse user populations, but collecting representative human data is often expensive o…

Generative AI collective behavior needs an interactionist paradigm

Laura Ferrarotti, Gian Maria Campedelli, Roberto Dessì +7

In this article, we argue that understanding the collective behavior of agents based on large language models (LLMs) is an essential area of inquiry, with important implications in…

Evaluating Generalization Capabilities of LLM-Based Agents in Mixed-Motive Scenarios Using Concordia

Chandler Smith, Marwa Abdulhai, Manfred Diaz +83

Large Language Model (LLM) agents have demonstrated impressive capabilities for social interaction and are increasingly being deployed in situations where they might engage with bo…

A Pragmatic View of AI Personhood

Joel Z. Leibo, Alexander Sasha Vezhnevets, William A. Cunningham +1

The emergence of agentic Artificial Intelligence (AI) is set to trigger a "Cambrian explosion" of new kinds of personhood. This paper proposes a pragmatic framework for navigating…

Beyond the high score: Prosocial ability profiles of multi-agent populations

Marko Tesic, Yue Zhao, Joel Z. Leibo +2

The development and evaluation of social capabilities in AI agents require complex environments where competitive and cooperative behaviours naturally emerge. While game-theoretic…

Virtual Agent Economies

Nenad Tomasev, Matija Franklin, Joel Z. Leibo +4

The rapid adoption of autonomous AI agents is giving rise to a new economic layer where agents transact and coordinate at scales and speeds beyond direct human oversight. We propos…

Multi-Actor Generative Artificial Intelligence as a Game Engine

Alexander Sasha Vezhnevets, Jayd Matyas, Logan Cross +6

Generative AI can be used in multi-actor environments with purposes ranging from social science modeling to interactive narrative and AI evaluation. Supporting this diversity of us…

Modeling human reputation-seeking behavior in a spatio-temporally complex public good provision game

Edward Hughes, Tina O. Zhu, Martin J. Chadwick +6

Multi-agent reinforcement learning algorithms are useful for simulating social behavior in settings that are too complex for other theoretical approaches like game theory. However,…

Using Large Language Models to Simulate Human Behavioural Experiments: Port of Mars

Oliver Slumbers, Joel Z. Leibo, Marco A. Janssen

Collective risk social dilemmas (CRSD) highlight a trade-off between individual preferences and the need for all to contribute toward achieving a group objective. Problems such as…

Societal and technological progress as sewing an ever-growing, ever-changing, patchy, and polychrome quilt

Joel Z. Leibo, Alexander Sasha Vezhnevets, William A. Cunningham +3

Artificial Intelligence (AI) systems are increasingly placed in positions where their decisions have real consequences, e.g., moderating online spaces, conducting research, and adv…
