Although AI is just a machine, it is known that people often anthropomorphize it and adopt a cooperative attitude. On the other hand, the factors and signals that make people exploitative toward AI are unknown. In this study, we measured whether people choose to cooperate with an AI that expresses self-deprecating, martyr-like, and individualistic facial expression patterns calculated by social value orientation in an iterated prisoner's dilemma. Experimental participants (n=379) were asked to choose 3 (expression patterns: Sad-Joy (masochism-martyrdom), Joy-Anger (individualism), Neutral-Neutral (neutral)) × 3 (opponents: Male, Female, Robot) We played a Prisoner's Dilemma game reconstructed as an investment game with an inter-participant factor. The results of the experiment showed that the AI exploited martyr-like facial expression patterns. This result suggests that human exploitability can be controlled by signaling.
