Artificial intelligence has made one thing unmistakably clear: data matters. The Data in Action Symposium brings together five scholar-practitioners working at the intersection of design, democracy, and Indigenous sovereignty to examine what happens when social life is translated into data. How does visualization shape social belief? What happens when humanities knowledge must become measurable to be valued? How does classification embed particular worldviews? And how might communities reclaim data as a condition of self-determination rather than extraction? Speakers include Abigail Echo-Hawk (Pawnee), Scott Weingart, Jennifer Guiliano, Yanni Loukissas, and Eli Holder. Drop-ins welcome. Sponsored by the Leslie Center for the Humanities and the Digital Humanities and Social Engagement Cluster.
