About

Dr. William Hagman is a pioneering researcher in human-robot interaction, with a focused expertise on how gender cues in robotic design influence human perception and behavior. His most-cited work, "He is not more persuasive than her" (2018), is a landmark study that systematically examines the effects of gendered voice and visual appearance in humanoid robots on persuasive communication. This research revealed that neither male nor female robot presentations inherently enhance persuasiveness, but instead interact with participant gender in nuanced ways—a finding that challenges assumptions about social robotics and has garnered 15 citations for its foundational insights. Hagman’s contributions extend to understanding how stereotypes and social dynamics transfer to human-machine interactions, offering critical guidance for designing more effective and equitable robotic systems. His work is notable for bridging social psychology and robotics, providing empirical evidence that robot gender design must consider user demographics to avoid unintended biases. For students and researchers, Hagman’s studies serve as a vital reference for exploring the intersection of technology, gender, and social influence, highlighting the importance of inclusive design in emerging technologies.
