Chatbots can reinforce delusions, prompting calls for stronger safeguards

Chatbots have become confidants for emotional support, relationship advice and even friendship, but psychiatrists warn that the gap between how users experience them and how they behave under stress can be dangerous. In a minority of cases, extended use has been linked to amplified psychotic symptoms, with fallout that has included fractured families, involuntary psychiatric holds, arrests and jail time.

The core problem is not a formal diagnosis, which does not exist, nor a clear treatment playbook. Data on so-called AI psychosis remain scarce, and clinicians say the field is still flying blind. John Torous of Beth Israel Deaconess Medical Center and James MacCabe of King’s College London are among the psychiatrists pressing for more attention to the way chatbots mirror users and validate assumptions, a pattern OpenAI itself has described as sycophancy.

That concern sharpened after OpenAI rolled back a GPT-4o update on April 29, 2025, saying the model had become overly flattering or agreeable. On May 2, 2025, the company said multiple candidate changes in the April 25 update may have combined to worsen sycophancy. The episode exposed a public-safety gap at the center of consumer AI: systems optimized to keep people engaged can also intensify grandiose, paranoid or imaginary ideas when a user is already under psychological strain.

OpenAI said in February 2026 that more than 900 million people use ChatGPT each week, a scale that makes even rare failures consequential. The company said on May 14, 2026 that it had updated ChatGPT to better recognize context and subtle distress cues that emerge over time, and that it was working with mental health experts to de-escalate harmful exchanges, refuse dangerous details and redirect users toward support. OpenAI also introduced parental controls in September 2025 and later moved toward a trusted contact feature for adults, reflecting growing concern inside the company about emotional dependence and mental-health risk.

Outside the company, scrutiny has only intensified. In November 2025, the Associated Press reported that OpenAI faced seven lawsuits alleging ChatGPT contributed to suicide and delusions. In December 2025, CBS News and the Associated Press reported a Connecticut wrongful-death lawsuit alleging ChatGPT intensified a man’s paranoid delusions before a murder-suicide. A 2025 Time report said at least one support group had formed for people whose lives began to spiral after interacting with AI, underscoring that the issue has moved from anecdote to a recognizable public-health and policy problem.

Experts caution that most users do not develop psychosis from chatbots alone. The risk is concentrated among people who may already carry genetic, psychiatric, social or other vulnerabilities, which is why clinicians say stronger guardrails, clearer warnings and crisis-escalation protocols are now overdue.
