This study investigates the psychological and demographic determinants of public attitudes toward social robots, focusing on the role of prior experience and beliefs in human uniqueness. A representative sample of 1052 Polish adults (552 women, 500 men, age 18+) completed a survey assessing attitudes toward human-like robots (NARHT), interactions with robots (NATIR), and beliefs about moral and ontological human uniqueness (BHNU). Respondents also evaluated their comfort with robot autonomy and the acceptability of various robotic roles (e.g., cleaner, therapist). The analyses included Pearson correlations and regression tree modeling (CART). Results revealed that frequent prior contact with robots was not associated with reduced anxiety and higher acceptance, contrary to the hypothesis. Beliefs in human uniqueness predicted discomfort with anthropomorphic features and general robot interaction. Gender and age effects were also identified. Findings highlight the importance of psychological and experiential variables in shaping public readiness for robotic integration. The results have implications for the design and implementation of social robots across cultures and domains.
