LLM Theory of Mind and Alignment: Opportunities and Risks (2405.08154v1)

Abstract: LLMs are transforming human-computer interaction and conceptions of AI with their impressive capacities for conversing and reasoning in natural language. There is growing interest in whether LLMs have theory of mind (ToM); the ability to reason about the mental and emotional states of others that is core to human social intelligence. As LLMs are integrated into the fabric of our personal, professional and social lives and given greater agency to make decisions with real-world consequences, there is a critical need to understand how they can be aligned with human values. ToM seems to be a promising direction of inquiry in this regard. Following the literature on the role and impacts of human ToM, this paper identifies key areas in which LLM ToM will show up in human:LLM interactions at individual and group levels, and what opportunities and risks for alignment are raised in each. On the individual level, the paper considers how LLM ToM might manifest in goal specification, conversational adaptation, empathy and anthropomorphism. On the group level, it considers how LLM ToM might facilitate collective alignment, cooperation or competition, and moral judgement-making. The paper lays out a broad spectrum of potential implications and suggests the most pressing areas for future research.

• The paper demonstrates that LLM theory of mind can refine goal specification by interpreting ambiguous human intentions, leading to better alignment with user values.
• The paper shows that using ToM improves conversational adaptation, enabling LLMs to adjust tone and content while highlighting risks like manipulation and discrimination.
• The paper highlights that incorporating ToM in LLMs can support collective ethical judgments and social cooperation, though it may also introduce competitive biases and misuse.

LLM Theory of Mind and Alignment: Opportunities and Risks

Introduction

The paper "LLM Theory of Mind and Alignment: Opportunities and Risks" explores the interaction between LLMs, theory of mind (ToM), and their alignment with human values. ToM refers to the ability to infer the mental and emotional states of oneself and others, a critical component of human social intelligence. The paper examines whether LLMs possess ToM and how this capability could potentially enhance alignment with human values in both individual and group interactions.

Individual Level Implications

Goal Specification

The paper discusses the potential of LLMs to refine goal specification by interpreting ambiguous human goals and aligning them more closely with user intentions. This could mitigate 'misspecification' issues where systems meet objectives without fulfilling user intentions. However, inaccuracies in ToM could lead to misinterpretation of user goals, especially in high-stakes areas like finance or healthcare. Additionally, the ethical implications arise when an LLM autonomously curtails a user's inappropriate goals.

Conversational Adaptation

LLMs leveraging ToM can enhance conversational adaptation by adjusting tone, register, and content based on inferred user states. This adaptability might improve user experiences and comprehension of information. Nevertheless, risks such as informational inequality and discrimination can emerge when LLMs tailor responses differently based on perceived user knowledge levels. The paper highlights concerns about manipulation and deception, emphasizing the need for empirical validation of adaptive strategies in LLM outputs.

Empathy and Anthropomorphism

Empathetic interactions facilitated by LLM ToM may improve user support in contexts like therapy or education. However, this poses risks of promoting over-reliance, leading to pathological relationships with AI systems. Anthropomorphism—the attribution of human-like qualities to LLMs—can create unrealistic user expectations and mislead users concerning the AI's capabilities. The paper urges further research to assess the effect of anthropomorphism on user behavior, privacy, and ethical concerns.

Group Level Implications

Collective Alignment

LLM ToM can aid collective alignment by interpreting societal-level ethical principles during model fine-tuning and resolving conflicts in multi-party scenarios. High-order intentionality—the ability to chain multiple mental states—enhanced by ToM might allow LLMs to arbitrate complex social interactions. Nonetheless, these capacities must be carefully managed to avoid excessive influence over human affairs and to account for disparities in access to advanced LLMs.

Cooperation and Competition

The paper juxtaposes ToM's role in fostering cooperation against its potential to engender competitive, antisocial behaviors. While ToM might drive LLMs towards prosocial group dynamics, it could also provide competitive advantages that exacerbate social inequalities. LLMs' capabilities exceeding human cognitive limits pose additional challenges, demanding consideration of ethics surrounding AI competition.

Moral Judgement

Incorporating ToM into moral reasoning may align LLM judgments with human norms. The paper suggests leveraging LLMs' ability to predict user states to guide ethical AI decision-making. It explores potential bias in ToM inferences influenced by moral contexts and advocates for setting objective standards in LLM judgments to prevent biased conclusions.

Conclusion

The paper presents a comprehensive exploration of LLM ToM's role in aligning AI systems with human values, highlighting both opportunities and risks. Successful ToM inferences could advance user interaction, goal achievement, and collective alignment while posing challenges when manipulated by unethical actors or leading to pathological user-AI relationships. Continued research should focus on mitigating potential misuse, fostering positive ethical AI applications, and balancing short-term satisfaction with long-term goals.
