This thesis is an investigation of the echo chamber phenomenon in news consumption on social networking sites. It incorporates elements of actor-network theory, Bruno Latour’s ‘matters-of-concern’ and Participatory Design methodology to identify and unpack contributing factors to the formation of echo chambers. As part of the research, a web tool called Echology was conceptualized during a series of workshops with news industry professionals. This paper describes the making of Echology, from ideation to actualization. The goal of this document and its accompanying design piece is to challenge readers to think critically about the forces at play in an online news experience.
