A Social-Identity Theory of Information-Access Regulation (SITIAR): Understanding the Psychology of Sharing and Withholding.

Secrecy, privacy, confidentiality, concealment, disclosure, and gossip all involve sharing and withholding access to information. However, existing theories do not account for the fundamental similarity between these concepts. Accordingly, it is unclear when sharing and withholding access to information will have positive or negative effects and why these effects might occur. We argue that these problems can be addressed by conceptualizing these phenomena more broadly as different kinds of information-access regulation. Furthermore, we outline a social-identity theory of information-access regulation (SITIAR) that proposes that information-access regulation shapes shared social identity, explaining why people who have access to information feel a sense of togetherness with others who have the same access and a sense of separation from those who do not. This theoretical framework unifies diverse findings across disparate lines of research and generates a number of novel predictions about how information-access regulation affects individuals and groups.
