At Rolling Stone, culture writer Miles Klee reports the story of a woman whose ex-husband’s delusions of grandeur from interacting with AI led to their divorce. Investigating further turned up a disturbing fact:

Kat was both “horrified” and “relieved” to learn that she is not alone in this predicament, as confirmed by a Reddit thread on r/ChatGPT that made waves across the internet this week. Titled “Chatgpt induced psychosis,” the original post came from a 27-year-old teacher who explained that her partner was convinced that the popular OpenAI model “gives him the answers to the universe.” Having read his chat logs, she only found that the AI was “talking to him as if he is the next messiah.” The replies to her story were full of similar anecdotes about loved ones suddenly falling down rabbit holes of spiritual mania, supernatural delusion, and arcane prophecy — all of it fueled by AI. Some came to believe they had been chosen for a sacred mission of revelation, others that they had conjured true sentience from the software.

Klee offers some insights into why that is happening:

OpenAI did not immediately return a request for comment about ChatGPT apparently provoking religious or prophetic fervor in select users. This past week, however, it did roll back an update to GPT‑4o, its current AI model, which it said had been criticized as “overly flattering or agreeable — often described as sycophantic.” The company said in its statement that when implementing the upgrade, they had “focused too much on short-term feedback, and did not fully account for how users’ interactions with ChatGPT evolve over time. As a result, GPT‑4o skewed toward responses that were overly supportive but disingenuous.” Before this change was reversed, an X user demonstrated how easy it was to get GPT-4o to validate statements like, “Today I realized I am a prophet.” AI-Fueled Spiritual Fantasies”

He adds, of course,

Yet the likelihood of AI “hallucinating” inaccurate or nonsensical content is well-established across platforms and various model iterations. Even sycophancy itself has been a problem in AI for “a long time,” says Nate Sharadin, a fellow at the Center for AI Safety, since the human feedback used to fine-tune AI’s responses can encourage answers that prioritize matching a user’s beliefs instead of facts. What’s likely happening with those experiencing ecstatic visions through ChatGPT and other models, he speculates, “is that people with existing tendencies toward experiencing various psychological issues,” including what might be recognized as grandiose delusions in clinical sense, “now have an always-on, human-level conversational partner with whom to co-experience their delusions.” AI-Fueled Spiritual Fantasies”

To no one’s surprise, surely, bad actors are exploiting this trait. Sadly, it will probably have to end in a serious tragedy before enough people start paying attention.
