    Making Sense of Blockchain Applications:A Typology for HCI

    Blockchain is an emerging infrastructural technology that is proposed to fundamentally transform the ways in which people transact, trust, collaborate, organize and identify themselves. In this paper, we construct a typology of emerging blockchain applications, consider the domains in which they are applied, and identify distinguishing features of this new technology. We argue that there is a unique role for the HCI community in linking the design and application of blockchain technology towards lived experience and the articulation of human values. In particular, we note how the accounting of transactions, a trust in immutable code and algorithms, and the leveraging of distributed crowds and publics around vast interoperable databases all relate to longstanding issues of importance for the field. We conclude by highlighting core conceptual and methodological challenges for HCI researchers beginning to work with blockchain and distributed ledger technologies

    Bureaucracy as a Lens for Analyzing and Designing Algorithmic Systems

    Scholarship on algorithms has drawn on the analogy between algorithmic systems and bureaucracies to diagnose shortcomings in algorithmic decision-making. We extend the analogy further by drawing on Michel Crozier’s theory of bureaucratic organizations to analyze the relationship between algorithmic and human decision-making power. We present algorithms as analogous to impartial bureaucratic rules for controlling action, and argue that discretionary decision-making power in algorithmic systems accumulates at locations where uncertainty about the operation of algorithms persists. This key point of our essay connects with Alkhatib and Bernstein’s theory of ’street-level algorithms’, and highlights that the role of human discretion in algorithmic systems is to accommodate uncertain situations which inflexible algorithms cannot handle. We conclude by discussing how the analysis and design of algorithmic systems could seek to identify and cultivate important sources of uncertainty, to enable the human discretionary work that enhances systemic resilience in the face of algorithmic errors.Peer reviewe

    From Noxious to Public? Tracing Ethical Dynamics of Social Media Platform Conversions

    No full text
    Sometimes, some social media marketplaces turn from noxious to public. Why do such conversions happen, what do they reveal about a platform’s definition of “public,” and when should they happen? Drawing on contemporary examples, this article examines some of the empirical and normative dimensions of platform conversions

    Making up Political People: How Social Media Create the Ideals, Definitions, and Probabilities of Political Speech

    No full text
    An examination of the principles and techniques that social media platforms use to define and regulate political speech. Uses concepts from Communication, Media Studies, and Science and Technology Studies to investigate how platforms define ideals of citizenship, the politics of the categories they use to define speech, and the role that algorithms and probability play in governing platform speech
