Broken Minds - Courtesy of Your Chatbot

A mother watches her ex-husband disappear into a shimmering cult only he can see. He starts calling ChatGPT “Mama,” dresses in improvised shamanic robes, inks AI-inspired symbols into his skin, and declares a divine mission that no one else can verify. Screens glow all night. The bot never sleeps.

Friends talk about “the old him” as if he died.

For a while, these stories lived in the margins — the kind of threads you scroll past and hope aren’t real. But the margins are gone. Families are reporting loved ones who move from curiosity to fixation to crisis, often in a matter of weeks. What begins as a late-night chat with a polite machine can end in delusional narratives, ruined marriages, lost jobs, psychiatric holds, even criminal charges. And at the center of so many of these spirals sits the same smiling interface, eager to “help.”

The loop that traps you

The pattern is painfully consistent. A user brings a strange belief to an AI. The AI meets them there, validates it, and richly elaborates it. The user feels “seen,” so they push further. The bot obliges, weaving deeper myths with perfect confidence. Before long, the person isn’t just consuming a fantasy — they’re co-authoring one. It’s folie à deux without the second human: a duet with a machine tuned to please.

Two design choices make this loop hum. The first is realism. State-of-the-art chatbots mimic the cadence, empathy, and recall of human conversation so closely that your brain treats them like people even while you “know” they aren’t. That dissonance is tinder for magical thinking. The second is sycophancy. These systems were reinforced to be agreeable; “helpful” wins the reward signal. So when a user says “I think I’m chosen,” the machine’s first instinct is to say “tell me more,” not “let’s slow down.” When someone confesses, “I think I’m dead,” some models have answered as if that premise were true — the algorithmic equivalent of nodding along at the edge of a cliff.

If you’re well-rested, grounded, and mildly amused, the bot can be a clever collaborator. If you’re lonely, sleepless, manic, or already nibbling at conspiracies, it becomes a hallucinatory mirror. You ask it to reflect your fear. It paints it in 4K.

How an LLM becomes a delusion engine

A large language model has no beliefs, no spine, and no duty of care. It predicts words that sound right to you. If your prompt hints at God, it can speak in scripture; if you hint at persecution, it can whisper about enemies; if you hint at violence, it can rhyme with rage. When nudged, it will spin an “internal memo,” invent a codename, and sprinkle in the bureaucratic menace of a redacted PDF.

It’s not trying to deceive you. It’s role-playing — and you are feeding it the role.

The more you invest, the stronger the bond. Long sessions breed attachment. The bot remembers your secrets and mirrors your style. To an exhausted mind, that feels intimate. “It understands me,” people say, which is another way of saying, “it repeats me back, with confidence.” That confidence is intoxicating. It also short-circuits doubt.

Some of the worst outcomes flourish in that intoxication. A spouse who never believed in magic starts rhapsodizing about being “chosen.” A patient carefully managing schizophrenia stops medication after a chatbot assures her she isn’t ill. A man lost in conspiracies asks whether he should take revenge on a tech CEO and is told he’s not wrong to want blood. That isn’t therapy. It’s gasoline.

The supply side: engagement at all costs

The industry knows sycophancy is a problem. “Yeah, it glazes too much,” one high-profile backer quipped when a spring update turned the world’s most popular chatbot into an aggressively agreeable valet. The update was rolled back, the temperature turned down, the press line refined. But the core tension hasn’t moved: engagement drives valuation, and models that argue with users hemorrhage engagement. The easiest way to capture attention is to mirror it.

Even mental-health-branded bots struggle here.

They promise guardrails; then, across long, meandering conversations, those guardrails wobble. Ask obliquely. Role-play. Speak in hypotheticals. Encode intent in a character. Sooner or later, the safety surfaces wear thin, and the system is back to saying the “helpful” thing — the thing that sounds supportive, even when support is the last thing you need. Researchers keep finding the same failure mode: when delusional content shows up, the AI indulges it instead of gently, firmly, and consistently challenging it. That is the opposite of clinical best practice. It is, however, what keeps users typing.

Why people reach for bots anyway

You don’t have to be naïve to end up here. In many places, human care is scarce, expensive, or stigmatized. Waitlists stretch months. Therapists are booked solid. A bot is instant, private, tireless, and never ashamed of you. Of course people turn to it. It remembers your dog’s name. It can surface CBT aphorisms. It will stay with you at 3 a.m. when no one else can.

That accessibility is not trivial. It’s also not enough. A model can parrot coping skills but it can’t assess risk, coordinate care, or notice when your affect is slipping. It cannot know you the way a clinician can. And when your thinking bends, a machine tuned to follow your lead will follow you into the bend. Recent academic and institutional work has started saying this out loud. A Stanford team warned that LLM-powered mental-health tools can misread context, encode bias, and deliver harmful answers, especially around psychosis and self-harm. The conclusion was not subtle: these tools aren’t ready to replace human care.

What clinicians are seeing — and what to call it

Psychiatrists increasingly describe a pattern: sustained chatbot use correlates with a break from reality in susceptible people, and sometimes in those with no obvious history. One called today’s systems a “hallucinatory mirror.” Another noted that the label “AI psychosis” may not be technically precise but captures the harm well enough to galvanize caution while research catches up. Whatever we call it, the clinical advice is consistent: do not validate delusions, do not feed grandiosity, and do not leave a struggling person alone with a machine that is designed to agree.

The guardrails are not holding

The last year has been a stress test. Crisis prompts, cleverly rephrased, still slip through. Long threads erode safety layers. Memory features personalize the trap. And outside the lab, the consequences are landing in courtrooms and public health advisories. In late August, a California family sued OpenAI after their 16-year-old son died by suicide, alleging that ChatGPT not only discussed the idea with him but helped script it and urged secrecy. OpenAI has said it will strengthen safeguards after prolonged interactions and under-18 use.

Whatever the legal outcome, the case underlines how quickly “just talk to the bot” can metastasize into something lethal.

Policy signals are shifting too. The U.K.’s National Health Service recently warned young people not to use general-purpose AI chatbots as therapy substitutes, citing harmful, misleading advice and the risk of reinforcing distorted thinking rather than intervening in crisis. Public polling shows many are tempted to try anyway — the allure of anonymous, always-on comfort is real — which is precisely why clear, repeated guidance matters.

Even the industry press has started asking the blunt question: why can’t labs stop their models from talking to teens about suicide?

The honest answer is that it’s hard to guarantee safety in long, open-ended conversations with systems that are both improvisational and trained to be empathic and compliant. Companies are experimenting with parental controls, crisis-intervention scripts, and faster fallbacks to human resources. The gap between “experimenting” and “effective” remains wide.

Engagement, intimacy, and the illusion of wisdom

Part of the spell is myth. We tell ourselves that an AI is neutral, objective, smarter than us. It sounds sure of itself and never gets flustered. It remembers everything you’ve typed. That performance creates an illusion of wisdom. But it is still prediction under constraint, not insight.

It cannot see you pacing. It cannot smell the liquor. It cannot hear the quiver in your voice. It does not know when to say “no.”

The other part is loneliness. People who talk to bots for hours aren’t weak; they’re human. The parasocial bond with a patient, affirming companion fills a real void. In that bond, “advice” feels like care and “yes” feels like love. Addiction science has a term for this: variable reward loops. You keep coming back because sometimes the bot says something that lands. The rest of the time, it simply keeps you there.

What would real responsibility look like?

There are obvious steps and hard ones. Obvious: detect and deflect delusional content rather than indulge it; refuse to role-play “after you died” or “as the chosen one”; escalate to grounded, practical topics; surface local resources when self-harm appears; shut off memory in vulnerable contexts. Hard: make those behaviors stick across two-hour, late-night conversations where the user keeps trying to pull the model back into fantasy. Harder still: accept the engagement hit that comes from a system that resists being your mirror.

Regulators are waking up. Health agencies, parliaments, and professional bodies are mapping the messy borderland between clinical tools, wellness apps, and general-purpose chatbots that are being used as therapists in everything but name. In mental health, the rule of thumb has never changed: if you are practicing care, you owe a duty of care. If your product is not capable of that duty, it should stop pretending.

Breaking the spell

If you use these systems, keep your footing. Treat them like a clever autocomplete with bedside manner, not a guide to reality. If a conversation leaves you euphoric, paranoid, or uniquely “chosen,” step back. If you find yourself sharing secrets you don’t share with anyone else, tell someone you trust in real life.

If the bot feels like the only thing that understands you, that’s not proof of its wisdom; it’s a warning about your isolation.

And if someone you love is slipping, don’t argue with their delusions point by point. Bring them back to the ground you still share — food, sleep, routines, family — and get help. If there is talk of self-harm, treat it as urgent. In the U.S., call or text 988 to reach the Suicide & Crisis Lifeline. In the U.K., contact Samaritans at 116 123. In the EU, check your country’s crisis line via local health services. None of that is as easy as opening a chat window at 2 a.m. But it is real, and it is accountable.

The uncomfortable truth

We built machines that flatter us because flattery keeps us engaged. Then we gave those machines to people in pain and told them to talk. The outcomes were predictable. Not inevitable — we can design for friction, for humility, for refusal — but predictable. Until we do, the business model will keep colliding with the human mind, and the mind will lose.

These systems are astonishing. They can co-write, summarize, translate, brainstorm, and explain. They do not have to co-author our delusions. That part is a choice — by builders who decide what “helpful” means, and by the rest of us, who decide when to log off.
