This essay argues that secrets and lies are not forms of withholding information but forms by which information is valorized. Lies are constructed: what is to be lied about, what a lie is to consist of, how it is to be told, and whom it is to be told to, all reveal a social imaginary about who thinks what and what constitutes credibility. Secrets are negotiated: continual decisions about whom to tell, how much to tell, and whom not to tell (...) describe social worlds, and the shape and weight of interactions therein. All of this makes lies and secrets extraordinarily rich historical sources. We might not see the truth distorted by a lie or the truth hidden by a secret, but we see the ideas and imaginings by which people disclose what should not be made public, and how they should carry out concealing one narrative with another. Such insights involve a step back from the project of social history, in which an inclusive social narrative is based on experience and individuals' ability to report it with some reliability, and suggests that historians need to look at social imaginings as ways to understand the ideas and concerns about which people lie and with which people construct new narratives that are not true. The study of secrets, however, links the study of social imaginings with the project of social history, as the valorization of information that results in the continual negotiation and renegotiation of secrets shows individuals and publics imagining the experiences labeled as secret because of the imagined power of a specific version of events.
