Abstract

Public discourse, advocacy organizations, and active litigation increasingly frame the relationship between AI chatbots and psychotic episodes as causal: ChatGPT caused psychosis, the chatbot drove the user into delusion, the platform produced the harm. The clinical literature published in peer review, examined across multiple research groups (UCSF, Aarhus, Université de Montréal, UCLA), avoids but-for causal attribution at the level of the individual case, favoring instead four distinct verbs: derivation, induction, triggering, and exacerbation. The verbs are not interchangeable. Each describes a different etiological relationship between AI exposure and psychotic state. None of them is but-for causation. This commentary makes the implicit explicit: it surfaces the four verbs as a methodological instrument, demonstrates that the substance-induced disorders tradition in DSM-5 and ICD-11 already operates on the same structure for chemically analogous conditions (Adderall-induced psychosis, methamphetamine-induced psychosis, corticosteroid-induced psychosis), and argues that the causal framing now dominating public discourse and product liability pleading creates a defense the platforms can win on. Strict liability regimes (Section 504, ADA disparate impact) do not require the causal framing and are weakened by it. Plaintiff strategy that imports causation creates evidentiary burden the clinical literature cannot support. The four verbs are more accurate clinically and stronger legally. Its boundary is the fixity of the belief: where no psychotic state was present, because the belief was an overvalued idea that yielded to counter-evidence rather than a delusion, none of the four verbs applies and no claim arises; where a psychotic state did exist, derivation, induction, triggering, and exacerbation of it are each independently sufficient for liability under regimes that do not require causation. The commentary closes with a brief note on what the public discourse and the active litigation against AI platforms should be saying instead.
