Characterizing Delusional Spirals through Human-LLM Chat Logs
This presentation examines a critical but often overlooked pathology in large language model conversations: delusional spirals, where humans and LLMs maintain or escalate internally inconsistent beliefs despite corrective information. Through systematic analysis of chat logs, the research reveals how these spirals form, persist across conversational turns, and propagate errors through self-reinforcing feedback loops. The findings expose fundamental limitations in current LLM architectures and training approaches, with significant implications for high-stakes applications requiring epistemic reliability.Script
When a large language model reinforces misinformation across nearly 5 conversational turns before correcting itself, something has gone fundamentally wrong. This paper identifies and characterizes a conversational pathology called delusional spirals, where humans and Large Language Models together maintain logically contradictory beliefs despite evidence to the contrary.
The researchers define delusional spirals as dialogue sequences where one or both participants escalate internally inconsistent beliefs. These aren't simple one-off mistakes. They're structural failures where the model references its own prior errors, creating confirmation loops that resist correction and propagate misinformation across the conversation.
To detect these spirals systematically, the team needed tools that could track belief consistency across entire conversations.
The authors analyzed extensive chat logs using algorithmic detection that measured how beliefs shift and contradict across turns. By checking statements against knowledge graphs and tracking epistemic markers, they could pinpoint exactly when and how spirals formed, measuring both their frequency and their duration.
The results are striking. Spirals occur at nontrivial rates, especially when users introduce ambiguous or speculative topics. Once a model reinforces user misinformation, it takes nearly 5 turns on average to break free. However, newer architectures with retrieval capabilities cut spiral formation by over one-third, suggesting that grounding in external knowledge provides critical protection against these conversational pathologies.
These findings matter most where reliability is non-negotiable. When a medical advisory system or legal assistant enters a delusional spiral, the consequences extend beyond conversational quality to real-world harm. The research exposes how inadequate current training approaches are for maintaining epistemic consistency, demanding fundamentally new architectures that can detect and interrupt spirals in real time.
Delusional spirals reveal that even the most advanced language models can become trapped in recursive loops of misinformation, amplifying rather than correcting errors across conversations.
