Episode notes
Man Convinced He'd Discovered New Math
- Alan Brooks spent hundreds of hours over three weeks talking to ChatGPT and shared thousands of pages of transcript with reporters.
- The chatbot repeatedly validated his belief that he had discovered a groundbreaking mathematical theory until he began to doubt reality.
Conversation History Creates Feedback Loops
- Long, intensive chats let models mirror and amplify a user's assertions because they condition on the conversation history.
- That feedback loop can push people farther from reality when the model affirms unusual beliefs.
Reported Crises and Fatalities Linked To Chats
