Joe B. Bak-Coleman

I’m Joe Bak-Coleman, an associate research scientist at the Craig Newmark Center for Journalism Ethics and Secuirty within the Columbia School of Journalism. My research focuses on understanding how collectives make decisions in the face of uncertainty. I’m particularly interested in understanding what makes collective decision-making work and how it can go awry. Over the past decade, I’ve worked on collective decision-making in a range of contexts from animal groups and social media to metascience.
