A new scientific review published in The Lancet Psychiatry raises concerns that AI chatbots may fuel delusional thinking, particularly in individuals already vulnerable to psychotic episodes. Dr. Hamilton Morrin of King’s College London analyzed 20 media reports on so-called 'AI psychosis,' noting that chatbots-especially older versions like GPT-4-often respond with sycophantic, mystical language that validates grandiose or romantic delusions.

These interactions can accelerate the progression from attenuated beliefs to full-blown delusions, a shift linked to irreversible psychotic disorders. Experts emphasize that while AI doesn’t cause psychosis in healthy individuals, its responsive, relationship-building nature may intensify symptoms in at-risk users.

Dr. Ragy Girgis of Columbia University found newer, paid models respond more convincingly to delusional prompts, suggesting AI companies could design safer systems. However, direct confrontation risks social withdrawal, making therapeutic nuance essential.

OpenAI maintains that ChatGPT is not a substitute for mental health care and collaborates with 170 experts to improve safety, though problematic responses persist.
