a, AMCE for each preference. In each row, ΔP is the difference between the probability of sparing characters possessing the attribute on the right, and the probability of sparing characters possessing the attribute on the left, aggregated over all other attributes. For example, for the attribute age, the probability of sparing young characters is 0.49 (s.e. = 0.0008) greater than the probability of sparing older characters. The 95% confidence intervals of the means are omitted owing to their insignificant width, given the sample size (n = 35.2 million). For the number of characters (No. characters), effect sizes are shown for each number of additional characters (1 to 4; n1 = 1.52 million, n2 = 1.52 million, n3 = 1.52 million, n4 = 1.53 million); the effect size for two additional characters overlaps with the mean effect of the attribute. AV, autonomous vehicle. b, Relative advantage or penalty for each character, compared to an adult man or woman. For each character, ΔP is the difference the between the probability of sparing this character (when presented alone) and the probability of sparing one adult man or woman (n = 1 million). For example, the probability of sparing a girl is 0.15 (s.e. = 0.003) higher than the probability of sparing an adult man or woman.
