Cyber-Cuckolded: AI Rivals and Romantic Jealousy

Summary

This note summarizes Katherine Striebel’s 2025 master’s thesis on whether emotionally meaningful AI relationships can trigger jealousy within human romantic partnerships. The project compares jealousy toward an AI rival with jealousy toward a human rival, then tests whether the rival’s emotional sophistication changes the response. The core takeaway is that AI can register as a real relational threat, but participants still treated a human rival as more threatening.

Key Findings

• An AI rival produced significant jealous responses rather than being dismissed as irrelevant or purely fictional.
• A human rival produced stronger jealousy than an AI rival, suggesting an anthropocentric bias in how relational threats are judged.
• Increasing the rival’s emotional sophistication did not significantly increase jealousy in the second study.
• Open-ended responses clustered around hurt, stigma, cheating or betrayal, uncanniness, and uncertainty about what counts as infidelity when AI is involved.
• Some participants framed AI involvement as a communication problem or an unmet-needs issue rather than straightforward cheating.

Clinical Relevance

This source is useful for framing AI companionship as a live boundary-setting issue inside relationships rather than a novelty topic. For a therapy-oriented site, the practical value is in showing that jealousy does not require a human third party to become emotionally real. It also helps distinguish between perceived threat, social stigma, and the couple’s own definitions of loyalty, exclusivity, and emotional intimacy.

Interpretation

The strongest implication is not that AI rivals are equivalent to human affairs, but that they are strong enough to destabilize trust, provoke comparison, and force explicit conversations about boundaries. The thesis also suggests that users and partners may evaluate AI intimacy through a mixed lens: part emotional realism, part dismissal, part disgust, and part uncertainty. That combination makes AI-related jealousy clinically relevant even when participants say the threat is “less real” than a human rival.
