Moral Utilitarianism and Attitudes Toward Animals

The majority of studies investigating attitudes toward animals have underscored the role of demographic and personality factors. The study of the role of general moral worldviews on attitudes toward animals represents an important complementary perspective. In the current study, we analyzed the relationship between moral utilitarianism toward humans and attitudes toward animals. In psychological and neuroscientific studies, moral utilitarianism has been shown to be related to empathy deficits. We expected that utilitarian decision making would be related to the endorsement of an instrumental representation of animals. We measured utilitarianism with the trolley problem, a hypothetical moral dilemma widely used in the psychological study of moral reasoning. A sample of 20,474 French adults answered an online survey measuring attitudes toward animals and moral decision making involving human beings. Results showed that irrespective of participants' age and gender, there was a slight relationship between utilitarianism measured by the trolley dilemma and the endorsement of an instrumental representation of animal. Limitations and implications for future research are considered.
