The Red Attraction Effect in Humanlike Robots at Robophilosophy 2026

The Robophilosophy 2026 conference took place from August 11–14, 2026, at University College Dublin (UCD) in Dublin, Ireland. Held under the theme „Connected Futures – Nature, Robots, and Society“, the seventh installment of the international conference series brought together researchers from a wide range of disciplines to explore how robotics and artificial intelligence are transforming human societies and the natural world. On the first day of the conference, Katharina Kühne presented the paper „No Red Romance for Robots? Investigating the Red Attraction Effect in Humanlike Robots“, authored by Emma Luisa M. Waller, Diana P. Ebenburger, Oliver Bendel, Martin Fischer, and herself. The study investigates whether the red-attraction effect known from research on human perception also occurs when people evaluate humanlike robots. From the abstract: „The color red has been shown to positively influence ratings of attractiveness and willingness to spend money (e.g., on a date), while having no effect on other perceptions, such as likeability. In an online study, we aimed to conceptually replicate the red-attraction effect using humanoid robots as stimuli. Forty-four heterosexual female participants evaluated 16 images of medium and highly humanlike robots on attractiveness, likeability, trustworthiness, and willingness to spend money to rent the robot. We found no evidence of a red-attraction effect. Female-looking robots received higher ratings overall. These findings have implications for robot design and suggest that basic cues, such as color, may not operate in the same way for robots. Instead, humanoid robots may constitute a distinct category but still be perceived as social agents.“ The proceedings, containing all conference papers, are expected to become available in late 2026.
