Perceived Trustworthiness of an Interactive Robotic System

This paper compares how much people trust in a robotic system and in a group of people. Our experiment focuses on trust in robot knowledge versus trust in collective human knowledge tested with the help of a quiz game. During the experiments, people are competing with each other and gain or lose points based on their decisions. A joker system was designed that provides evidence on whether people rely rather on the robot or on human collective knowledge. In this setup, perceived intelligence is therefore highly correlated with trustworthiness. In the scope of this joker-picking system, overall results show that the trust in the robotic system is higher than the trust in collective human knowledge.
