Holding Animal-Based Research to Our Highest Ethical Standards: Re-seeing Two Emergent Laboratory Practices and the Ethical Significance of Research Animal Dissent.

"Animal-based research should be held to the highest ethical standards" is becoming an increasingly common refrain. Though I think such a commitment is what we should expect of those using animals in science, much as we would if the participants were humans, some key insights of discussions in applied ethics and moral philosophy only seem to slowly impact what reasonably qualifies as the highest standards in animal research ethics. Early in my paper, I will explain some of these insights and loosely tie them to animal research ethics. Two emergent practices in laboratory animal science, positive reinforcement training and "rehoming," will then be discussed, and I will defend the view that both should be mandatory on no more ethical grounds than what is outlined in the first section. I will also provide reasons for foregrounding the moral significance of dissent and why, most of the time, an animal research subject's sustained dissent should be respected. Taken together, what I will defend promises to change how at least some animals are used in science and what happens to them afterwards. But I will also show how an objective ethics requires nothing less. Ignoring these constraints in the scientific use of animals comes at the cost of abandoning any claim to adhering to our highest ethical standards and, arguably, any claim to the moral legitimacy of such scientific use.
