Commentators often attempt to refute the nothing-to-hide argument by pointing to things people want to hide. But the problem with the nothing-to-hide argument is the underlying assumption that privacy is about hiding bad things. By accepting this assumption, we concede far too much ground and invite an unproductive discussion about information that people would very likely want to hide. As the computer-security specialist Schneier aptly notes, the nothing-to-hide argument stems from a faulty “premise that privacy is about hiding a wrong.” Surveillance, for example, can inhibit such lawful activities as free speech, free association, and other First Amendment rights essential for democracy.

The deeper problem with the nothing-to-hide argument is that it myopically views privacy as a form of secrecy. In contrast, understanding privacy as a plurality of related issues demonstrates that the disclosure of bad things is just one among many difficulties caused by government security measures. To return to my discussion of literary metaphors, the problems are not just Orwellian but Kafkaesque. Government information-gathering programs are problematic even if no information that people want to hide is uncovered. In The Trial, the problem is not inhibited behavior but rather a suffocating powerlessness and vulnerability created by the court system’s use of personal data and its denial to the protagonist of any knowledge of or participation in the process. The harms are bureaucratic ones—indifference, error, abuse, frustration, and lack of transparency and accountability.
