For the start of 2017, Dave Karpf is back on the podcast with his new book, Analytic Activism: Digital Listening and the New Political Strategy (Oxford University Press, 2016). Karpf is associate professor of media and public affairs at The George Washington University and author of The MoveOn Effect also published by Oxford. Much of the attention paid to digital politics is about speech. What did Donald Trump say on Twitter today? And who responded? Karpf’s book suggest that that attention has overlooked the other side of digital politics: listening. In Analytic Activism, Karpf focuses on how organizations use the digital footprints we all leave online to inform strategy. A/B testing and digital petitions allow political groups to hear what constituents care about and then later to use that information to mobilize and drive action.
