Moral reasoning and concern for the environment

The relation between Kohlberg's cognitive moral reasoning and concern for the environment was measured in 158 college students. Rest's Defining Issues Test and Thompson and Barton's measure of environmental attitudes were administered. Principled moral reasoning, the weighted ranking of responses at the most advanced level of moral development, correlated positively with ecocentrism (belief in the intrinsic importance of nature), negatively with environmental apathy, and was unrelated to anthropocentrism (belief that nature is important because it is central to human wellbeing). Ecocentrism, the only attitude that has been found in previous research to correspond with environmentally friendly behavior, was predicted by principled moral reasoning, gender, and college major.
