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…

Meaning Is Not A Metric: Using LLMs to make cultural context legible at scale

Cody Kommers, Drew Hemment, Maria Antoniak +4

This position paper argues that large language models (LLMs) can make cultural context, and therefore human meaning, legible at an unprecedented scale in AI-based sociotechnical sy…

Quantifying the Self-Interest Level of Markov Social Dilemmas

Richard Willis, Yali Du, Joel Z Leibo +1

This paper introduces a novel method for estimating the self-interest level of Markov social dilemmas. We extend the concept of self-interest level from normal-form games to Markov…
