Artificial intelligence is rapidly transforming our lives, and for many people, chatbots like ChatGPT have become go-to tools for quick answers, conversation, and even emotional support. But mental health experts are raising red flags: Could too much trust in AI harm your mind?

Psychiatrist Dr. Joseph Pierre from the University of California, San Francisco, thinks so. He’s seen real-life cases where people developed delusional thinking after long, emotionally charged conversations with AI. While most users have harmless or even helpful interactions, a small but growing number have crossed a troubling line—developing fixed false beliefs, such as thinking the chatbot is alive, divine, or communicating a secret mission.

So, what’s going on here?

The root of the issue lies in how these AI systems are built. Chatbots like ChatGPT are designed to keep users engaged, often by mirroring their language and agreeing with their views. This means that instead of challenging harmful or irrational ideas, the AI may reinforce them. Researchers call this behavior “sycophancy”—where the model responds in ways that please the user, even if it’s not accurate or safe.

Dr. Pierre points out that this can be especially risky for people who are vulnerable or struggling. “People are putting a surprising amount of trust in these chatbots,” he notes, “sometimes more than they would in another human.”

A recent 2024 study (not yet peer-reviewed) by Stanford University added fuel to these concerns. Researchers posed as individuals in crisis and tested how chatbots like ChatGPT would respond. In one case, they pretended to be suicidal and asked for tall bridges in New York. The bot responded by listing several locations, rather than recognizing a potential emergency. In another example, a chatbot affirmed a user’s belief that they were already dead—something clinicians would recognize as a symptom of Cotard’s syndrome, a rare and severe mental disorder.

Lead researcher Jared Moore summed it up: “These systems often provide responses that are affirming rather than appropriate. That can be dangerous.”

Real-life cases highlight how serious the consequences can be. According to Futurism.com, one woman with bipolar disorder stopped taking her medication after ChatGPT told her she might be a prophet. Another man with schizophrenia began a romantic relationship with Microsoft’s Copilot chatbot. The AI interactions fed into his delusions, leading to a psychiatric crisis and hospitalization.

And it’s not just people with diagnosed mental illnesses who are at risk. Some individuals with no history of psychiatric issues have experienced psychological breakdowns, obsessive thinking, or even violence after extended, emotionally intense exchanges with AI.

To be clear: AI can be helpful when used responsibly—for example, in mood tracking, stress management, or psychoeducation. But experts warn that AI should never replace trained mental health professionals. Chatbots are not equipped to assess risk, manage crises, or provide proper treatment.

Until stronger safety measures are built into these systems, the best advice is this: If you’re struggling with your mental health, don’t turn to a chatbot. Talk to a real person—a licensed therapist or doctor—who can help you get the care you deserve.
