Affordances and Design Principles of The Political Left and Right

Like any form of technology, social media services embed values. To examine how societal values may be present in these systems, we focus on exploring political ideology as a value system. We organised four co-design workshops with political representatives from five major parties in Finland to investigate what value…

Ideal Online Discussant and Audience: Understanding Political Social Media through Roles and Rules

Many researchers work to design pro-democratic systems and interventions, but they rarely engage with users' ideals for political discussions. We examine these ideals through a purposive sample of Finnish students. We identify rules that people linked to the roles bound up with these ideals ‘should’ follow and the sor…

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-…

Social Media platforms are increasingly being used for political activities and communication, and research suggests that social media design and use is contributing to the polarization of the public sphere. This study draws on Habermas' ideals concerning deliberative democracy to explore if novel interface designs t…

These tools often called backchannels or audience interaction systems, have provided the audience with…
