Building on the specification of our information-related identity interests in the preceding chapter, this penultimate chapter sets out the source and scope of other parties’ ethical responsibilities to meet these interests. These are obligations accruing chiefly to those who hold personal bioinformation about us or are in a possible to control its disclosure. This chapter argues that disclosure responsibilities are grounded in the strength of our interests in developing and maintaining inhabitable self-narratives, combined with our mutual dependence on and vulnerability to the conduct of others when it comes to fulfilling this interest. These factors ground ethical ‘responsibilities to help’ by offering, providing, or facilitating access to personal bioinformation or, sometimes, refraining from doing so. These are pro tanto responsibilities – they hold in the absence of stronger countervailing reasons to do otherwise. They will also vary depending on the nature of the information and the roles and relationship between potential discloser and recipient. These responsibilities extend not only to those to offer and disclose personal bioinformation but also to ascertain potential recipients’ identity needs and to disclose in discursive, individually responsive, and identity-supporting ways. The chapter explains what this kind of identity support entails.
