MIT researchers modelled a "delusional spiral" in which a sycophantic chatbot can reinforce false beliefs even when its answers are true, but the study does not test this on real users. A separate preregistered experiment (n=1,590) found that warning users about sycophancy changed their trust, not their susceptibility to persuasion.
