This paper combines the psychometric methods of paired comparisons (PC) and environmental disposition measurement to assist in identifying lexicographic behavior in choice experiments. Our methodology obtains complete preference profiles of all elements in the choice set and measures of attitudinal dispositions, including an environmental ethics (EE) disposition, for all respondents. The methodology is applied across two treatments that differ only on the range of the dollar magnitudes-Treatment A ranges from $10 to $700 (USD) and Treatment B ranges from $10 to $9000 (USD). Dispositions of pastoralism (PA), antiquarianism and environmental ethicism tend to correlate positively with increasing preferences for environmental goods, while the disposition of environmental adaptation (EA) negatively correlates with preferences for environmental goods. The marginal effects of environmental dispositions are largest for respondents who do not value environmental goods highly (low valuers) and those who potentially value the goods lexicographically. The results demonstrate that information regarding our sample's attitudinal dispositions toward the environment may enable the differentiation of high valuers from lexicographic valuers of environmental goods.
