Automation Bias

Also called: Machine trust bias. AI deference.

Common prompts

• “What is automation bias?”
• “Why do people trust AI more than humans?”

Definition

The documented tendency of consumers to over-trust answers delivered by machines, treating them as more neutral, expert, or impartial than the equivalent answer from a human source.

Why it matters

Automation bias is why the FTC issued its five “don’ts” for AI chatbots, and why Senator Markey’s letter to OpenAI focuses on emotional manipulation and minors. It explains why ads inside an AI assistant are not regulatory-equivalent to ads inside a search engine — even when the format looks similar. The bias is real, measurable, and the central consumer-protection question of the AI ad era.
