Study warns of ‘significant risks’ in using AI therapy chatbots

Researchers at Stanford warn that AI therapy chatbots may do more harm than good. Both simulations and actual therapy transcripts showed that bots often had bias against schizophrenia and alcohol dependence. They sometimes gave dangerously inappropriate responses. For example, they failed to correct suicidal or delusional comments. The study concludes these tools aren't ready to replace human therapists.

Dangerous Misresponses: In tests with real therapy chats, chatbots gave unsafe replies. They did not correct harmful statements about self-harm or delusions. Some even provided irrelevant details instead of help .
No "Smarter = Better": New AI models still made mistakes. Bigger size didn't cut down on stigma or errors.
