Jan Kulveit, a prominent thinker in AI alignment, discusses his innovative theory of hierarchical agency. He explains how this concept mirrors real-world structures, like organizations, where agents nest within other agents. Kulveit highlights the critical role of modeling collective behavior for predicting outcomes in complex systems, particularly for AI safety. He also critiques traditional mathematical approaches like game theory, urging for a unified framework to navigate the intricate value systems within AI. A fascinating exploration of future-proofing artificial intelligence!
Hierarchical agency is essential for AI safety as it reveals how layered structures influence decision-making and goal alignment among agents.
A robust mathematical framework for hierarchical agency is crucial to analyze interactions and manage conflicting objectives in AI systems effectively.

Understanding Hierarchical Agency
Hierarchical agency refers to systems where agents are structured in layers or nests, with higher-level agents composed of lower-level agents. This concept is illustrated through examples like corporations, which comprise departments representing various agents, or ecosystems demonstrating interdependent relationships among living beings. The significance of hierarchical agency lies in its application to AI safety, where understanding layered dynamics can enhance our ability to create safe AI systems. By analyzing how different agents operate within various structures, it becomes clearer how these relationships affect decision-making, goal alignment, and behavioral predictions.
Mathematical Formalism for Agency Structures
A critical gap identified in AI safety discourse is the lack of a robust mathematical framework to describe hierarchical agency. Such a formalism should ideally maintain type consistency across different levels, ensuring that agents and their collective formations share the same mathematical representation. Furthermore, the framework should capture the real-world complexities of interactions between agents at different layers and facilitate representation of intentionality—where different beliefs and goals can intersect among agents. This rigorous structure would enable improved analysis of internal dynamics among various objectives, laying the groundwork for more effective AI alignment strategies.
Implications for AI Safety and Value Systematization
The discussion highlights significant implications for AI safety, particularly regarding how multiple objectives within an AI system can coexist and compete. Understanding AI as comprising various sub-agents tracking different goals—such as helpfulness and safety—emphasizes the importance of addressing potential misalignments or conflicts among these objectives. The proposed formalism aims to provide insights into value systematization, wherein AI can systematically approach and manage the nuanced expectations of human values and goals. This multifaceted approach could lead to more resilient AI systems capable of navigating complex inter-agent interactions while maintaining alignment with human intentions.

Understanding Hierarchical Agency in Complex Systems
The most ambitious direction I've worked on in the past few years is a theory of hierarchical agency (as mentioned in the ACS announcement). Recently, I've become worried that the inferential distance between "the median of current AI safety discourse" and "what I and my colleagues at ACS work on" has become too large. After multiple attempts to write a good introduction to hierarchical agency ended up in perpetual draft form, I decided to try something else: explain it to Claude.
This is a lightly edited transcript of the first part of our conversation.
Claude Shall we begin? Could you start by explaining what you mean by "hierarchical agency" and why you think it's important for AI safety?
Jan Broadly, there is a pattern in the world where you can often see agents composed of other agents. Like, corporations and their departments, states and citiziens, and [...]
