# AI systems rated AI-generated content higher

**Context.** Researchers found what they call **AI-AI bias** (see [[concept-ai-ai-bias]]). Puntoni's framing: "Think about what that means. In a world where AI agents make purchasing decisions, people-created marketing might lose out not because it's worse but because of structural biases in how AI evaluates information." This is the evidentiary anchor for the contrarian claim [[contrarian-ai-marketing-superiority]].
