Participants rated AI-generated dating profile responses equally as human-like in terms of closeness and romantic interest, challenging assumptions about authenticity in online communication.

Methods: Participants evaluated 10 AI-generated responses to an interpersonal closeness task in a matchmaking scenario, without knowing the responses were AI-generated.

Key Findings: Impact of perceived response source (human vs AI) on interpersonal closeness and romantic interest; influence of perceived quality and human-likeness.

Limitations: Findings may not generalize to other contexts beyond matchmaking or interactions constrained by specific tasks like the Interpersonal Closeness Generating Task.
