About

Nathan G. Freier is a pioneering researcher at the intersection of human-robot interaction (HRI), developmental psychology, and moral philosophy, whose work has fundamentally shaped our understanding of how humans — particularly children — form social and ethical relationships with robotic systems. With over 1,000 cumulative citations, Freier's research has established him as a significant voice in examining the psychological and moral dimensions of robotic companions. His most influential contribution, "Robovie, you'll have to go into the closet now" (2012, 416 citations), offered groundbreaking empirical insight into how children across different developmental stages perceive humanoid robots as genuine social and moral entities. Complementing this, his longitudinal work on robotic pets like Sony's AIBO explored how even preschool-aged children engage meaningfully with robotic companions. His 2012 study on moral accountability for robot-caused harm (162 citations) further probed whether humans extend ethical judgments to machines — a question of profound contemporary relevance. Freier also contributed practically to the field through design pattern frameworks for sociality in HRI (172 citations) and offered philosophical grounding by proposing psychological benchmarks for humanlike robots. His work ultimately challenges researchers, designers, and ethicists to reckon seriously with the deepening bonds humans are forming with increasingly sophisticated robotic others.
