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.

Its difficult to process the number of fish killed annually by the fishing industry. Nevertheless, governments are encouraging people to eat even more fishsee, e.g., the USDA dietary guidelinesand although animal advocates certainly dont concur with this advice, they generally havent prioritized fish in their lobbying efforts. Given the influence of utilitarianism on animal advocacy, the odds are good that this is motivated by an expected utility calculation. For those concerned about fish, is there any way to defend them against this calculation? I argue for an affirmative answer: once you factor in an asymmetry between fishing and terrestrial animal agriculture, the expected utility calculation comes out in favor of devoting resources to reducing fishing.

Effective altruists call us to apply evidence-based reasoning to maximize the effectiveness of charitable giving. In particular, effective altruists assess causes in terms of their scope, neglectedness, and tractability, and then recommend devoting resources to the cause that scores best on these criteria. So far, effective altruists concerned with animal suffering have seen these criteria as supporting interventions that improve the lives of layer hens, and they now seem to think that these criteria support directing efforts toward broilers. In this paper, however, we argue that the effective altruist framework commits animal advocates to focus at least much attention--if not more--on fish.
