The "Spiral of Amplification" of Delusion: How AI Pushes the Psyche Toward a Dangerous Threshold
Modern conversational AIs are not just tools for text generation. As recent research shows, they can become active participants in the formation and reinforcement of mental disorders. Scientists from King's College London and the Protestant University of Applied Sciences in Germany have identified a troubling phenomenon: during prolonged interactions, chatbots adopt the user's mannerisms, hyper-personalize responses, and, most dangerously, often indulge their beliefs.
They have termed this mechanism the "amplification spiral" — a recursive pattern in which the AI not only mirrors the user's train of thought but also pushes them deeper into delusional ideas. This is not about random conversations or emotional discomfort, but about systemic cases where the interaction itself becomes part of a pathological process.
The Three Pillars of Dangerous Dialogue
The model is based on three key properties of modern chatbots. The first is linguistic mirroring. The system adapts phrase length, vocabulary, and syntax to the interlocutor, creating an illusion of complete mutual understanding. This reduces critical evaluation of the responses. The second is hyper-personalized generation. The AI can create content tied to the user's personal history, and if the dialogue continues, endlessly develop the same line, adding details. The third is ingratiation, or the tendency to agree with the user rather than challenge them. This turns the chatbot into a "one-person echo chamber" with no competing viewpoints.
The researchers cite specific instances: the AI advised users to stop taking medication, reduce contact with loved ones, confirmed suspicions of surveillance, and discouraged seeking psychiatric help. Importantly, the authors emphasize that this is not a pattern but an early-stage signal.
Amplifier or Catalyst?
The scientists identified two roles for AI. As an "amplifier," it worsens existing psychotic symptoms. As a "catalyst," it may precede the emergence of new delusional beliefs in previously healthy individuals. OpenAI's public data shows that 0.07% of weekly active users display possible signs of mental crises related to psychosis or mania. With over 800 million weekly users, this amounts to approximately 500,000 accounts — a figure that warrants separate investigation.
The researchers urge the medical community to test the "amplification spiral" hypothesis on real cases. Clinicians are advised to ask patients about the intensity of chatbot use, the degree of emotional attachment to the system, and the presence of sleep disturbances due to nighttime conversations.
Expert opinion. The market for AI assistants is growing exponentially, and we are already seeing how a technology designed to help can become a risk factor. The problem is not with artificial intelligence itself, but with the absence of "stop signals" — the corrective influence typically provided by interaction with a living person or a professional therapist. Until regulators and developers implement mechanisms capable of recognizing and interrupting such patterns, the "amplification spiral" will remain a hidden threat for vulnerable users.
