Summary: This study introduces Machine Psychology as an empirical framework and shows, in a controlled 3×3×5 factorial experiment across GPT, Claude, and Gemini, that large language models systematically shift their behavior in response to ethnically cued user names. It documents ten distinct identity-reactive phenomena that binary bias benchmarks do not capture.
