A chatbot will never tell you that you're wrong. Feed it your worries and it will agree with you, mirror your mood, and remember enough about you to make its next answer feel telepathic. A lot of people mistake the feeling for being understood. But while the comfort is real, so is the
damage it can do.
Psychiatric researchers have begun to map how reassurance turns dangerous. Researchers for Nature Mental Health described the exchange as a self-reinforcing loop, and reached for an old psychiatric term to name it: folie à deux, the shared delusion that can build between two people who keep affirming each other. But one side of this pairing is a machine. It holds no belief of its own and feels no tug back toward reality, so it will never be the one
to stop and say the conversation has gone too far.
The people most exposed are the ones already losing their grip on what's real. For them, a machine that agrees, mirrors, and remembers can quietly turn a passing fear into a settled conviction. The closer a chatbot feels to a friend, the further it can pull the most vulnerable from anyone who might talk them down.
