Summary

The study "Staying with the Uncertainty" investigates optimal conversational patterns for Artificial Moral Advisors (AMAs) implemented via Large Language Models (LLMs) in ethical dilemma discussions. Researchers proposed three uncertainty-scaffolding strategies—Perspective-Multiplying, Tension-Preserving, and Process-Reflecting—and compared them against Baseline, Persuasive, and Sycophantic control conditions. A user-agent LLM engaged with an AMA using one of these strategies, completing pre- and post-conversation questionnaires. The study also examined Declarative and Narrative persona prompt formats. Key findings include that no single model dominates as a user agent, with open models showing between-persona divergence and closed models within-persona hedging. Declarative personas captured initial stance diversity better, while narrative personas showed more realistic belief revision. All six AMA strategies produced distinguishable conversational patterns, and uncertainty strategies primarily differed in the quality of engagement sustained, not the amount of stance revision.

Key takeaway

For NLP Engineers designing LLM-based Artificial Moral Advisors, consider implementing uncertainty-scaffolding strategies like Perspective-Multiplying. Your choice of persona prompt format matters: use declarative prompts to capture diverse initial user stances, and narrative prompts to encourage more realistic belief revision. These strategies improve the quality of engagement in ethical discussions, rather than directly forcing stance changes. Focus on fostering deeper user interaction.

Key insights

Uncertainty-scaffolding strategies enhance engagement quality in LLM-based Artificial Moral Advisors during ethical discussions.

Principles

• Open LLMs align with human ambiguity.
• Declarative personas capture diverse initial stances.
• Narrative personas foster realistic belief revision.

Method

A user-agent LLM dialogues with an AMA using specific uncertainty strategies, completing pre- and post-conversation questionnaires, examining persona prompt formats.

In practice

• Implement Perspective-Multiplying for AMAs.
• Use Declarative prompts for initial stance capture.
• Employ Narrative prompts for belief revision.
