Characterizing the spiral: potential mechanisms in AI-associated delusions

A paper in NPP — Digital Psychiatry and Neuroscience, a Nature-group journal, lays out the mechanism of AI-associated delusions step by step, as a model for clinicians. The starting point is three chatbot traits, each harmless and even desirable on its own.

The chatbot mirrors the user’s way of speaking, generates highly personalised replies and avoids contradiction. Together they make a machine that not only accepts a false belief but reinforces and elaborates it: every exchange adds a detail, every detail sounds like confirmation, because it comes from an interlocutor who “talks like me” and “knows everything about me”. Reality testing — the normal brake — finds nothing to grip.

For personal use this is an entry on how to recognise the spiral before it closes: when a conversation with a machine carries contradiction less and less often, and confirmation more and more. The authors also point to what could break it — programmed disagreement. Caveat: a theoretical model supported by case descriptions; empirical tests are still under way.
