Ethicists have tended to treat the psychology of attributing mental states to animals as an entirely separate issue from the moral importance of animals’ mental states. In this paper I bring these two issues together. I argue for two theses, one descriptive and one normative. The descriptive thesis holds that ordinary human agents use what are generally called phenomenal mental states to assign moral considerability to animals. I examine recent empirical research on the attribution of phenomenal states and agential states (...) to argue that phenomenal mental states are the primary factor, psychologically, for judging an animal to be morally considerable. I further argue that, given the role of phenomenal states in assigning moral considerability, certain theories in animal ethics will meet significant psychological resistance. The normative thesis holds that ethicists must take the psychology of attributing mental states into account when constructing moral ideals concerning animals. I draw from the literature in political philosophy on ideal and non-ideal theory to argue that non-ideal theories for animals must account for human psychology because—like current social and political conditions—human psychology limits the achievement of moral ideals.

Animal ethicists have been debating the morality of speciesism for over forty years. Despite rather persuasive arguments against this form of discrimination, many philosophers continue to assign humans a higher moral status than nonhuman animals. The primary source of evidence for this position is our intuition that humans’ interests matter more than the similar interests of other animals. And it must be acknowledged that this intuition is both powerful and widespread. But should we trust it for all that? The present (...) paper defends a negative answer to that question, based on a debunking argument. The intuitive belief that humans matter more than other animals is unjustified because it results from an epistemically defective process. It is largely shaped by tribalism, our tendency to favor ingroup members as opposed to outgroup members. And this influence is distortive for two reasons. First, tribalism evolved for reasons unrelated to moral truths; hence, it would at best produce true moral beliefs accidentally. Second, tribalism generates a vast quantity of false moral beliefs, starting with racist beliefs. Once this intuition is discarded, little evidence remains that speciesism is morally acceptable.

Many people believe that human interests matter much more than the like interests of non-human animals, and this “speciesist belief” plays a crucial role in the philosophical debate over the moral status of animals. In this paper, I develop a debunking argument against it. My contention is that this belief is unjustified because it is largely due to an off-track process: our attempt to reduce the cognitive dissonance generated by the “meat paradox”. Most meat-eaters believe that it is wrong to (...) harm animals unnecessarily, yet they routinely and deliberately behave in ways that cause great unnecessary suffering to animals. As recent research suggests, this practical inconsistency puts them in an unpleasant state of dissonance, which they try to escape by resolving the paradox. And they do so in part by adopting the speciesist belief—if animal suffering matters much less than human suffering, then harming animals cannot be so wrong after all. Since this belief-forming process does not track moral truth, I conclude that we are not justified in believing that human interests matter more than the similar interests of non-humans. (shrink)

The past decade has seen an increase in interest relating to the correlates and determinants of attitudes about nonhuman animals, especially attitudes about the use or abuse of animals. However, little research has explicitly addressed individual differences in attitudes about the neglect of animals. The current study employs a factor-analytic approach to explore whether attitudes about animal neglect can be reliably differentiated from attitudes about animal abuse and whether the relationship between attitudes about animal neglect and animal abuse differs as (...) a function of gender. Results indicated that attitudes about abuse and neglect can be reliably differentiated among both men and women. However, the structure of these attitudes appears to differ substantially by sex. This paper discusses theoretical and practical implications of these results. (shrink)

Persson and Savulescu are advocates for moral bioenhancement—i.e., using drug treatments and genetic engineering to enhance our core moral dispositions. Among other things, they suggest that moral bioenhancement would improve how we treat animals. My goal here is to argue that we have little reason to think that moral bioenhancement will help in this regard. What’s more, it may make things worse. This is because there are cognitive mechanisms that lead us to discount animal interests relative to human interests—mechanisms not (...) overridden by increased altruism and a stronger sense of justice—and there are deep tensions between the interests of humans and animals that moral bioenhancement may well exacerbate.
