This chapter focuses on the embedded values approach, which holds that computer systems and software are capable of harbouring embedded or 'builtin' values, and on two derivative approaches, disclosive computer ethics and value-sensitive design (VSD). Disclosive computer ethics focuses on morally opaque practices in computing and aims to identify, analyse and morally evaluate such practices. Many practices in computing are morally opaque because they depend on computer systems that contain embedded values that are not recognized as such. Therefore, disclosive ethics frequently focuses on such embedded values. Value-sensitive design is a framework for accounting for values in a comprehensive manner in the design of systems and software. The embedded values approach could benefit from more theoretical and conceptual work, particularly regarding the very notion of an embedded value and its relation to both the material features of artefacts and their context of use.
