This chapter develops the conceptual foundations of informative ICTs by interrogating how information is produced, structured, and made meaningful in contexts of digital abundance. Tracing the evolution of “information” from Shannon’s technical theory through human–computer interaction and critical social science perspectives, the chapter argues that access alone does not guarantee informativeness. Instead, informativeness emerges when ICTs are designed to support transparency, reliability, and equity in information practices. Drawing on interdisciplinary scholarship and qualitative empirical grounding in India, the chapter introduces social entropy as a key analytical concept to capture the productive and destructive uncertainties that arise when information systems intersect with unequal social contexts. By integrating technical, human, and societal layers of analysis, the chapter proposes a two-tier framework for evaluating ICTs as sociotechnical systems oriented toward information integrity and the social good.
