Anthropic's new index shows pretty AI code stops us from thinking
Anthropic just released its AI Fluency Index analyzing 9,830 Claude.ai chats to see how people actually collaborate with AI. The team found that multi-turn iteration doubled collaborative skills, but users were 3.1 percentage points less likely to question Claude's logic whenever it produced polished artifacts like code or documents. Basically, the cleaner the output looks, the less humans bother to check it.
