In two studies, we used the Ethics Position Questionnaire (EPQ) to investigate the relationship between individual differences in moral philosophy, involvement in the animal rights movement, and attitudes toward the treatment of animals. In the first, 600 animal rights activists attending a national demonstration and 266 nonactivist college students were given the EPQ. Analysis of the returns from 157 activists and 198 students indicated that the activists were more likely than the students to hold an "absolutist" moral orientation (high idealism, (...) low relativism). In the second study, 169 students were given the EPQ with a scale designed to measure attitudes toward the treatment of animals. Multiple regression showed that gender and the EPQ dimension of idealism were related to attitudes toward animal use. (shrink)

One hundred sixty subjects acted as members of a hypothetical Institutional Animal Care and Use Committee and evaluated five proposals in which animals were to be used for research or educational purposes. They were asked to approve or reject the proposals and to indicate what factors were important in reaching their ethical decisions. Gender and differences in personal moral philosophy were related to approval decisions. The reasons given for the decisions fell into three main categories: metacognitive statements, factors related to (...) the animal, and factors related to the design of the experiment. (shrink)

Heuristics provide insight into the inconsistencies that characterize thinking related to the use of nonhuman animals. We examine paradoxes in judgments and policy related to the treatment of animals in science from a moral intuition perspective. Sunstein's ideas are consistent with a model of animal-related ethical evaluation we developed twenty-five years ago and which appear readily formulated as moral heuristics.
