Abstract: Recent work on privacy suggests many nonhuman animals may have a right to privacy from humans (e.g., Pepper, 2020). If animals can have a right to privacy, there might be potentially widespread implications for our interactions with the domesticated animals who live with us, the captive animals on display in zoos and being studied in laboratory facilities, and the wild animals who share spaces with us. How can we identify the contexts in which an animal deserves privacy from humans? In this paper, I argue that one way to identify these contexts is to identify and understand animal social norms. By studying animal social norms, we stand to learn what personal information animals need to control in order to have successful social relationships. Further, understanding animal privacy through social norms facilitates a better understanding of when humans might violate the privacy of animals. I discuss two ways: humans might interfere with behaviors governed by the norms of that animal’s community, and humans may violate the norms of a human-animal interspecies community structured by social norms. In both cases, studying animal social norms, and especially interspecies communities, will facilitate more concrete judgments about when animals deserve privacy and how we can respect their right.
