Possible concerns about agricultural robots. All areas of possible concern are measured on a five-point Likert scale (n = 2,269). For the graphs, we grouped 1 (“Strongly disagree”) and 2 (“Rather disagree”) into the category “No concern”, and 4 (“Rather agree”) and 5 (“Strongly agree”) into the category “Concern”. * indicates a significant Kruskal–Wallis test and a significant difference between at least one treatment group and the control group, as shown in Supplementary Information Table S8.
