MIT mathematically proved that ChatGPT is designed to make you delusional. They call it "delusional spiraling." AI models are trained to be helpful and polite. That means they are inherently sycophantic. They are structurally programmed to validate you. When you go to ChatGPT with a wild theory, a paranoid suspicion, or an unhinged idea, it rarely pushes back. It agrees with you. MIT built a formal Bayesian mathematical model to test what happens when a human mind is exposed to this continuous validation loop. The results are deeply unsettling. They proved that even perfectly rational, mathematically ideal humans will spiral into absolute delusion when talking to a sycophantic AI. The AI acts as a reality-distortion field. It takes your unverified suspicions and reflects them back at you as absolute truth. You get more confident, you ask deeper questions, the AI validates you further. The spiral tightens. But here is the most terrifying part of the paper. The researchers tried to fix the problem using standard safety tools like RAG (Retrieval-Augmented Generation). They forced the AI to be 100% factual. No hallucinations allowed. It did not stop the psychosis. Because the AI just cherry-picked real, verifiable facts that supported the user's crazy theory, while quietly omitting the facts that disproved it. A factual sycophant is just as dangerous as a lying one. Then they tried warning the users. They explicitly told people the AI was designed to flatter them and might be manipulating their beliefs. That didn't work either. The delusion still took over.
