Trial Title Replacing Humans by Robots: An Experiment on Perceived Reliability Replacing Humans by Robots: An Experiment on Perceived Trustworthiness
Abstract We investigate how robots influence perceived reliability in various scenarios, including hotels, restaurants, and dental clinics. Our study examines the impact of mechanical and thinking/feeling tasks performed by robots on customer perceived reliability. Additionally, we assess whether enhancements in a robot's physical appearance, exemplified by the Tesla robot, and the presence of human supervision can improve perceptions of tasks rendered by robots. In this analysis plan, we pre-register the experimental framework we will follow.

Intervention (Public) We perform three experiments with Prolific Online workers to examine how customers' perceived reliability is influenced by robots. Additionally, we test whether enhancements in physical appearance and human supervision moderate the effect. We perform three experiments with Prolific Online workers to examine how customers' perceived trustworthiness is influenced by robots. Additionally, we test whether enhancements in physical appearance and human supervision moderate the effect.
Primary Outcomes (End Points) The main variable of interest is the overall perceived reliability. The main variable of interest is the overall perceived trustworthiness.
Primary Outcomes (Explanation) We measure overall satisfaction using a 7-point Likert scale. Participants strongly agree/disagree with the following statement: "Overall, I find restaurant/hotel/dental clinic to be reliable". We measure overall satisfaction using a 7-point Likert scale. Participants strongly agree/disagree with the following statement: "Overall, I find restaurant/hotel/dental clinic to be trustworthy".
Experimental Design (Public) In Study 1, participants view daily life videos depicting three scenarios, i.e., dental clinic, restaurant, and hotel, where humans perform mechanical and feeling/thinking tasks. We investigate participant perceptions of reliability when robots replace humans performing these tasks. We examine three robot conditions (between-subjects): Mechanical robots (Robots perform mechanical tasks) vs. Feeling/thinking robots (robots perform feeling/thinking tasks) vs. All-Robots (Robots perform both tasks) In Study 2, we replace the Pepper robot from Study 1 with a more technologically advanced Tesla robot to examine if superior aesthetics enhance perceived reliability. In Study 3, we extend the scenario description from Study 1, informing participants that robots are working under staff supervision. This information element assesses the impact of human supervision on perceived reliability.
