Narration-of-Thought: Inference-Time Scaffolding for Defeasible Ethical Reasoning in Large Language Models

arXiv:2606.26366v1 Announce Type: new Abstract: Standard chain-of-thought on moral dilemmas exhibits two failure modes: stakeholder collapse (the trace names at most one party with a stake in the outcome) and uncertainty suppression (no explicit unknowns or hedges before committing to an action). We introduce narration-of-thought (NoT), a system prompt that structures chain-of-thought into five sections: protagonist, stakeholders, two-step consequences, uncertainty, then commitment. NoT adds no training, parameters, or fine-tuning. On 100 DailyDilemmas scenarios across four generators from thr

Why this matters
Why now

The proliferation of advanced LLMs necessitates robust ethical reasoning capabilities, especially as these models become more integrated into decision-making processes.

Why it’s important

Improving ethical reasoning in LLMs addresses critical safety and alignment concerns, paving the way for more reliable and trustworthy AI systems in sensitive applications.

What changes

A new, scaffolded prompt engineering technique demonstrably enhances ethical reasoning by encouraging more comprehensive consideration of stakeholders and uncertainties, without requiring model retraining.

Winners
  • · AI developers
  • · Ethical AI researchers
  • · Industries deploying AI in sensitive contexts
Losers
  • · Developers relying solely on basic chain-of-thought
  • · Users experiencing unpredictable AI ethical failures
Second-order effects
Direct

Incorporation of 'narration-of-thought' methodologies becomes a standard practice in ethical AI development.

Second

Increased public and regulatory trust in AI systems due to more transparent and defensible ethical decision-making processes.

Third

Reduced likelihood of AI-induced moral hazards and externalities, accelerating AI adoption in highly regulated sectors.
