 If the attributes are deemed perfectly substitutable (meaning that only the sum, potentially weighted, of the attributes matters for the assessment of individual advantage), and the inequality aversion is zero (meaning that only the sum of individual indexes of advantage matters), the two distributions are considered equally good. But they also appear equally good if there is no possible substitution (only the value of the worst attribute matters) and inequality aversion is infinite (only the worst-off individual matters). In contrast, the first distribution appears worse if the attributes are substitutable and inequality aversion is strong (the first distribution is then unequal, unlike the second one); whereas it appears better if there is no possible substitution and inequality aversion is weak (only one individual has a bad attribute in the first distribution, whereas both have one in the second).
