In this dissertation, I study large-scale civic conversations where technology extends the range of “discourse visibility” beyond what human eyes and ears can meaningfully process without technical assistance. Analyzing government documents on digital innovation in government, emerging data activism practices, and large-scale civic conversations on social media, I advance a rhetoric for productively listening to democratic discourse as it is practiced in 2016. I propose practical strategies for how various governments—from the local to the United Nations international climate talks—might appropriately use technical interventions to assist civic dialogues and make civic decisions. Acknowledging that we must not lose the value that comes from face-to-face civic deliberation, I suggest practical pathways for how and when to use technology to increase democratic engagement from all stakeholders.
