Do privacy rights restrict what is permissible to infer about others based on statistical evidence? This paper replies affirmatively by defending the following symmetry: there is not necessarily a morally relevant difference between directly appropriating people’s private information—say, by using an X-ray device on their private safes—and using predictive technologies to infer the same content, at least in cases where the evidence has a roughly similar probative value. This conclusion is of theoretical interest because a comprehensive justification of the thought (...) that statistical inferences can violate privacy rights is lacking in the current literature. Secondly, the conclusion is of practical interest due to the need for moral assessment of emerging predictive algorithms. (shrink)

Most studies on the ethics of privacy focus on what others ought to do to accommodate our interest in privacy. I focus on a related but distinct question that has attracted less attention in the literature: When, if ever, does morality require us to safeguard our own privacy? While we often have prudential reasons for safeguarding our privacy, we are also, at least sometimes, morally required to do so. I argue that we, sometimes, ought to safeguard our privacy for the (...) sake of the possible wrongdoer, in order to prevent the possible wrongdoer from committing a morally defiling act that renders them worse off. I illustrate the variety of cases in which this duty binds us and contrast my view to some other claims in the literature which also purport to show that we sometimes have a duty to safeguard our own privacy.
